In this day and age, everything seems to be getting smaller. Our phones are getting smaller, laptops are getting smaller, and even our cars are getting smaller. It feels great to invest in a product that’s both small and powerful because it allows us to have more freedom and control in the palm of our hands.

When it comes to investing in smaller and smaller products, however, it’s more important than ever that we’re aware of the potential problems of downsizing. For example, a small car may be able to zip around corners and save you a lot of money on gas, but is it able to provide you with the safety that you want and need?

This is no different when it comes to portable oxygen concentrators. Introduced in the early 2000s, these new medical oxygen devices offered an alternative to the clunky and dangerous oxygen tanks that came before them. Manufacturers wanted to push the limits of what was possible, so they’ve been making portable oxygen concentrators smaller and smaller ever since then — but this has often been at the expense of the consumer.

There’s a lot more that goes into a great portable oxygen concentrator than size; oxygen output, weight, reliability, battery life, and ease-of-use are also very important factors to consider. As such, if you want to find the best POC for you, it’s important to take all of these into consideration. Having a small portable oxygen unit is great, but only if it excels in other ways as well.

In this blog, we’ll take a look at two of the smallest portable oxygen concentrators on the market: the Inogen One G5 and the Respironics SimplyGo Mini to help you determine which one is right for you. If you have any questions, please leave them in the comment section below or address them with a respiratory specialist.

Respironics SimplyGo Mini Overview

Respironics is a world leader in respiratory and sleep products. Founded in 1976 by Gerald E. McGinnis, the company mainly focused on sleep apnea products like CPAP machines but later branched out to include bi-level technology in 1992 and eventually portable oxygen concentrators in the 2000s. 

Respironics boasts two portable oxygen concentrators: the Respironics SimplyGo (continuous flow) and the Respironics SimplyGo Mini (pulse flow). Each unit has its pros and cons, but each one claims to be one of the lightest and most efficient POCs in its class while still offering the quality and reliability you’d expect from a Respironics product.

One unique aspect of this Philips oxygen concentrator is the touch screen display. Where most concentrators have physical buttons you can press, the SimplyGo Mini only has a “power” button and a “home” button. The rest of the unit’s functions are controlled by the touch screen. If you’ve never used a touch screen, however, don’t be intimidated. The SimplyGo mini has on-screen cues that will help you navigate its features quickly and effectively.

Inogen One G5 Overview

Inogen is widely considered to be the best portable oxygen concentrator manufacturer in the world. It was founded in the early 2000s with the conviction that technology in the medical oxygen field was not keeping up with the desires of COPD patients and that medical professions needed to try something new.   

Inogen began work on their Inogen One G series of portable oxygen concentrators which aimed to provide oxygen patients with significantly more freedom than their oxygen tanks. Since then, we have seen five generations of Inogen oxygen machines along with other high quality products such as the Inogen at Home Oxygen Concentrator, as well as a host of accessories like backpacks, carrying cases,  external battery chargers and more which help patients get the most out of their machines.

The Inogen One G5 portable oxygen concentrator is the latest POC by Inogen, offering an extended battery life and higher oxygen output than previous iterations. Having been released this past summer, it’s a relatively new unit, but that hasn’t stopped it from quickly becoming one of the most beloved POCs on the market, especially since it has such a reputable brand to back it up.

Oxygen Output

Oftentimes, one of the best places to start when comparing two oxygen concentrators is their oxygen output. After all, it’s very difficult to start examining other features of a medical oxygen device if it doesn’t provide you with the level of oxygen that you need. 

Both the Inogen One G5 and the Respironics SimplyGo Mini are pulse flow units. What this means is that they have built-in technology that only delivers oxygen when you inhale. This enables manufacturers to make much smaller lightweight units, but they may not be ideal for patients with high-flow oxygen therapy needs.

What’s more, the Respironics SimplyGo Mini Offers a flow setting of 5 while the Inogen One G5 offers a flow setting of 6, the highest option available for a pulse flow unit. No other pulse flow oxygen concentrator on the market can go up to a flow setting of 6. If you want to go any higher, you’ll need to switch over to continuous flow machines which are much heavier and bulkier.

This is not to say that the SimplyGo Mini is bad in terms of oxygen output. A setting of 5 is good when compared to most pulse flow oxygen concentrators. If you typically stay at a setting of 2 or 3 and your doctor tells you that a setting of 5 is enough, then the SimplyGo Mini may be a great option for you.

Battery Life

Another one of the most sought-after features of a portable oxygen concentrator is its battery life. A long battery life is what enables oxygen users to go where they want, when they want, and stay out for longer without having to get to a wall outlet to charge their device.

When someone brings up battery life in portable oxygen concentrators, they’re often compared to oxygen tanks. The average portable E cylinder will work for about 5 hours before it runs out of oxygen. An even smaller tank, the D cylinder, will go for about 3 hours before running out. Fortunately, both the G5 and the SimplyGo Mini offer much more freedom than that.

On a flow setting of one, the Inogen One G5 can attain an outstanding 13 hours of battery life on one charge using the double battery pack. The SimplyGo Mini is not far behind with a maximum battery life of 9 hours on a setting of two using the extended battery pack. Either way, this leaves you tons of breathing room (no pun intended) while you’re out and about to do as you please without having to go back home to charge your battery.

If 13 hours of battery life isn’t enough or you need to use a higher setting which drains more battery life, you can always carry an extra battery on you. The double battery only weighs a pound more than the single battery, so you won’t have any trouble carrying an extra one in your G5 backpack or carrying bag. Likewise, with the SimplyGo Mini, you’ll also have the option of carrying an extra battery or extended battery.

Ease-of-Use

The Inogen One G5 and SimplyGo Mini both have a lot to offer in terms of ease-of-use. Just so we’re clear on what this means, ease-of-use refers to how easily settings can be changed or adjustments can be made to your concentrator on the fly. It’s important to have an oxygen concentrator that’s easy to use so that you don’t waste time fiddling with it while you’re away from home. 

Both these pulse flow portable oxygen concentrators have a simple interface. The screen and the controls are built into the top of the unit so you won’t have to lift the device up or strain yourself to make changes to it. The G5 display shows your remaining battery life, flow setting, audible alerts, and errors. The SimplyGo Mini, on the other hand, is almost entirely touch screen. You’ll be able to make pulse flow setting adjustments without ever using any buttons.

Another factor that contributes to ease-of-use is the battery pack. On both the Inogen One G5 and SimplyGo Mini, you’ll be happy to know that the batter can be slipped on and off easily by simply pulling the tab on the front of the case. The G5 battery will slide off the back of the unit and the SimplyGo Mini battery will slide sideways off the device. 

If you decide to purchase a G5, you’ll need to remove your filters and wash them every couple of weeks to a month. Fortunately, this is really easy to do. Simply remove the intake vent filters from the front and back of the unit, clean it using a mild dish soap, and make sure it is thoroughly rinsed and dried before putting it back on the device. It’s imperative that you do not run the concentrator without the filters because it prevents air particles from damaging internal components and ensures that you’re always breathing clean air.

There are plenty of great accessories available for both devices as well that can contribute to how easy they are to use. For example, you can purchase either the G5 custom carrying case or G5 backpack which gives you ample ways to carry your Inogen G5. For the SimplyGo Mini, you may opt for accessories like the external battery charger or the carrying cart. 

Size

Size can really be a deal breaker when you’re choosing an oxygen concentrator. If your device is too large, you’re going to have a lot of problems traveling with it especially if you need to get on a plane or a bus. While bulkier oxygen concentrators like the SeQual Equinox are approved by the Federal Aviation Administration (FAA) and most cruise lines, that doesn’t mean you’ll have a pleasant experience while you’re traveling with them. 

On the other hand, pulse flow units like the Inogen One G5 and the SImplyGo Mini are small enough that you won’t have any problems traveling with them or finding a place to store them on a plane or bus. The Inogen One G5 is 8.15" H x 7.19" L x 3.26" W and the SimplyGo Mini is 9.4” H x 8.3” L x 3.6” W so the G5 is slightly smaller but not by a huge margin.

If you travel by air a lot, there’s no understating how convenient it is to have a small portable oxygen concentrator. The aisles on most airplanes are really narrow, so if your oxygen concentrator isn’t able to fit between them, you may have to pick it up or have someone else carry it for you. You’re supposed to put your belongings under a seat when you take off but if your concentrator is too bulky, you may have to hold it in your lap, which can be a safety hazard.

Let’s face it, we all have to go to the bathroom at least once when we’re on a flight. Airplane bathrooms are tiny enough as it is, but if you have an oxygen concentrator with you, it can feel nigh impossible. At less than a foot in width and height, however, the G5 and SimplyGo Mini won’t add any unnecessary bulk and you won’t have to worry about bumping other passengers on the way to the bathroom either.

Sound Level

Noise is often a factor that many oxygen users are concerned about when purchasing a portable oxygen concentrator for the first time. They don’t want to disturb people or get kicked out of a library or wherever they’re going. While this is certainly an understandable concern, even the loudest portable oxygen concentrators are pretty quiet. 

The Inogen One G5 is only 37 decibels (dBA) on a setting of 2 and the SImplyGo Mini is only 43 decibels on a setting of 2. That’s about the volume of a quiet whisper or gentle hum sound. Most people report getting used to the sound after a few times of using it and that it doesn’t disrupt other people when they’re around it. A difference of 6 decibels may sound like a lot, but when you hear the two devices side-by-side, you probably wouldn’t even know the difference.

The Ideal Candidate for the SimplyGo Mini

The SimplyGo Mini portable Oxygen Concentrator is one of the most popular units on the market and it’s backed by a company that’s been a leader in sleep and respiratory health for decades. Philips Respironics is known for producing medical oxygen equipment that’s durable, reliable, and powerful.

If you’re considering the Respironics SimplyGo Mini, it’s unlikely you’ll be let down. This medical oxygen device excels in nearly every aspect of its design like weight, size, battery life, and ease-of-use. The one thing to note, however, is that it goes up to a maximum flow setting of 5, as opposed to a flow setting of 6 like the Inogen One G5. So, you’ll need to speak with your pulmonologist beforehand to make sure this won’t be a problem.

When compared to the G5, the SimplyGo Mini lacks in most areas. However, the differences are minimal in many cases, and depending on what your needs are, you may find that the SimplyGo fulfills your needs perfectly. Cost is another aspect to consider when purchasing a portable oxygen concentrator and there are so many deals going around that it’s impossible to say which unit will be cheaper at any given time.

The ideal Candidate for the Inogen One G5

Inogen is unlike Respironics in that it was created with the sole purpose of making medical oxygen more accessible and convenient for respiratory patients. Inogen broke barriers with their G1 oxygen concentrator back in the early 2000s and they continue to break barriers with their latest portable oxygen concentrator, the Inogen One G5.

The G5 broke records for the most external battery life of any POC as well as having the highest oxygen output of any pulse flow POC. This is a deal breaker for many oxygen patients because if they need a device with a flow setting of 6, they no longer need to switch over to a heavier, bulkier continuous flow unit. The added battery life affords oxygen patients the freedom to stay out of their house for longer and have more peace of mind while traveling.

All in all, the Inogen One G5 is the best portable oxygen concentrator for the greatest number of people. The G5 was released this past summer so it’s one of the newest POCs available, meaning replacement parts are widely available and technical support is in full force. However, it’s unlikely you’ll need either of these for some time because the G5 has had a very low failure rate right out the gate.  

Conclusion

Ultimately, you can’t go wrong with either the Inogen One G5 or the Respironics SimplyGo Mini. Both oxygen machines are backed by reputable medical oxygen companies that have proven their commitment to customers for decades. Both units are fully supported with replacement parts and technical support so you won’t have to worry about your device breaking a year or two down the line. 

While it’s great to have a preference in which POC you want, you should first consider your medical needs. Before purchasing a portable oxygen concentrator, speak with your doctor and pulmonologist to learn exactly what your oxygen needs are. This way you can invest in a unit that offers you plenty of breathing room in case your disease progresses or you experience an exacerbation.

Possibly the most notable achievement of the Inogen One G5 is its battery life. As opposed to previous portable oxygen concentrators, the G5 afforded oxygen patients ample usage time with up to 13 hours of battery life on a flow setting of 1 and up to 3 hours on its highest setting (a setting of 6). This means that even patients with the highest oxygen demands can stay out and about for longer than ever before. 

By excelling in all aspects of design like weight, size, battery life, cost, oxygen output, and reliability, the G5 set a new precedent for oxygen concentrator manufacturers. No longer would oxygen patients have to “settle” for below-average battery life or sacrifice their personal freedom and independence just to get the oxygen they need — the Inogen One G5 does it all.

{{cta('fa8abc2a-1e88-4fa3-82fd-1cb5b9ed43b2','justifycenter')}}

While you’ve probably already read a lot about the G5 itself, you may be wondering what accessories are available for it. G5 accessories are by no means necessary for you to experience the benefits of this oxygen machine, but they certainly help if you want to make the most of it. Read on as we take a look at 7 must-have accessories for your Inogen One G5 portable oxygen concentrator and be sure to leave a comment if you have any questions.

The Inogen One G5 Custom Carrying Case

The most fundamental Inogen One G5 accessory is the custom carrying case. This simple accessory provides G5 owners with the easiest and most effective way to carry their portable oxygen concentrator whether they’re simply taking a trip to the store or going on a long vacation around the world.

The custom carrying case is designed for the minimalist. Rather than offering tons of extra storage pockets, it has just enough room to carry small objects like a driver’s license, a grocery list, or your Inogen One G5 manual. But most importantly, it keeps your concentrator at your side as you go about your daily life. It also has the ability to carry a G5 with either the single or double battery attached.

Prevents Scratches and Dents

If you’re not already aware, the Inogen One G5 doesn’t have any place to clip a shoulder strap onto. As a result, you’ll need to have a case to carry it in like the G5 custom carrying case. Fortunately, this case provides ample protection so you’ll never have to worry about scratches, dents, or cracks.

Although the G5 is already a solid unit that resists damage with its hard outer shell, like any electronic device, it’s still susceptible to internal damage. The custom case is padded enough to prevent minor damage but thin enough that it won’t add a significant amount of bulk to the unit. You’ll be able to carry your oxygen unit wherever you please, even in busy or overcrowded areas, and still have the peace of mind knowing that your concentrator is safe.

Easy to Use

The G5 custom carrying case makes it incredibly easy to transport your POC. If you’re worried that you won’t be able to use your concentrator as easily, think again! When you slip the G5 into the carrying case, simply lift the flap on the top to access the control panel. There’s an open area in the back so that you can plug in an AC or DC power adapter. What’s more, to change batteries, all you need to do is unzip the bottom of the bag. Another reason the G5 carrying case is easy to use is that you can adjust the carrying strap to your liking. The strap has an adjustable pad on it so you’ll never feel uncomfortable while carrying your POC. 

The Inogen One G5 Backpack

The G5 backpack is the opposite of the custom carrying case in many ways. While the custom carrying case opts for a minimalist approach, the backpack is designed for those who want to carry a lot of personal belongings with them. The obvious downside to this is that you’ll need to take the backpack off to check your battery life, oxygen purity status, and alerts, however, the control panel can be easily accessed without even having to remove it from the backpack. Note that the Inogen One G5 backpack can hold both G5s with single batteries and G5s with double batteries.

Perfect for Traveling

If you’re someone who loves to travel and explore the world, the G5 backpack has a lot to offer you. While it’s certainly important to travel light on long trips, you also need to make sure that what you do take is stored in the most efficient way possible. On the G5 backpack, you’ll find a large storage compartment for personal belongings and a pouch on the back of the bag allowing you to keep everything separate. 

Your Inogen One G5 will fit snugly into the pouch meaning it won’t jostle around or fall out. The top of the POC is only partially covered, so you’ll still be able to check the screen, use the buttons, and plug in your cannula while it’s in the pouch. There is also a mesh material where the air intake is so that you ensure it’s always operating how it should be. 

Comfortable to Wear

Let’s face it, if you’re traveling around the world and doing a lot of walking, the last thing you want is an uncomfortable backpack. Fortunately, the G5 backpack delivers in this category. Like the custom carrying case, the G5 backpack has adjustable shoulder straps to help you find the right fit. They’re also padded so they won’t dig into your shoulders.

Another reason the G5 backpack is so comfortable is that the G5 won’t hang down or move around as you walk. Naturally, the farther something protrudes out from a backpack, the more strain it will cause on your back. However, with this backpack, the G5 is held close to the main storage compartment so there won’t be any unnecessary strain on your back and shoulders. 

The Inogen One G5 Single Battery

The single battery is the same one that comes with your Inogen One G5 portable oxygen concentrator. However, if you’re in need of more battery life on the go, an extra one may be just the thing you’re looking for. It’s called a “single battery” because it has just one cell in it. This cell has one anode and cathode which is separated by electrolyte, used to produce both a voltage and a current. 

Lightweight Design

The Inogen One G5 is only 4.7 pounds with a single battery attached to it and a single battery by itself only weighs about 8 ounces. So even when you’re carrying an extra single battery with you, it will still weigh less than most portable oxygen concentrators on the market. Inogen has spent several decades refining the technology in their batteries allowing oxygen patients to have a longer battery life in a smaller and more lightweight battery. The single battery offers up to 6.5 hours of life on a flow setting of 1.

Easy to Replace

If you’re looking for extra batteries for your G5, chances are, you’re on the go often. If that’s the case, you’ll be happy to know that Inogen G5 batteries are extremely easy to remove and replace. Simply press the release tab that’s on the side of your G5. The battery will pop off of the unit and you can then put the new battery in its place. Make sure you push upwards so that it clicks into place and it’s secure while you’re going about your daily business.

The Inogen One G5 Double Battery

Some people get confused when they hear “G5 double battery” because they think it comes with two separate batteries, however, the word “double” is referring to the number of cells in its casing. In this case, the double battery provides twice as much battery life as the single battery. If you’re going on a long vacation or you’re planning on being away from home for a while, there’s no understating the importance of having a G5 double battery with you. 

Ample Battery Life

The G5 double battery pack is equipped with up to 13 hours of battery life on a flow setting of 1. This is the longest external battery life of any portable oxygen concentrator on the market and offers an ample amount of freedom for you to be out and about as long as you please without having to replace your battery or find an outlet to charge your device.

If that’s not enough, you’ll be happy to know that the double battery isn’t a whole lot bigger than the single battery and it’s still very lightweight. The double battery weighs in at just 12 ounces, only 4 ounces more than the G5 single battery. In other words, you’re getting twice the battery life with a 50% increase in weight. This makes the double battery the most efficient battery option for the Inogen One G5.

Plenty of Options to Fit Your Lifestyle

The main takeaway when it comes to Inogen One G5 batteries is that they offer plenty of options to fit your lifestyle whether you’re super active and want to get out as much as possible, or you just need to get to the store once a week.

The Inogen One G5 comes with a single battery attached to it. This means you’ll get up to 6.5 hours of battery life right out of the box. If you want to extend that battery life, however, you can purchase either an extra single battery or an extra double battery. Two single batteries would provide you with up to 13 hours of battery life and a single and double battery would provide you with an astounding 19.5 hours of battery life! What’s more, you’d only be carrying 5.75 pounds of weight in total, that’s still less than other pulse flow portable oxygen concentrators like the Oxlife Freedom and the AirSep Freestyle 5. 

The Inogen One G5 DC Power Cable

One thing we get very excited to tell oxygen patients about is the Inogen One G5 DC power supply. Why do we like this accessory so much? Because it adds to the many ways the G5 offers you freedom and independence throughout your daily life. Nobody wants to live in a world where they have to count down the hours of freedom they have the moment they live their home in the morning, it’s more reassuring to know that you’ll have access to oxygen wherever you go and the DC power supply offers this.

Perfect for Road Trips

We’ve already talked a lot about flying and taking a cruise with the Inogen One G5, but what about taking a road trip? The G5 DC charging cable allows you to charge your G5 in any vehicle with a cigarette outlet, so you’ll be able to keep your concentrator fully charged during your whole trip. 

If you need to get out and do some sightseeing or to stretch your legs, you’ll have peace of mind knowing that you have a fully charged battery to work with. Once you get to the hotel or wherever you’re staying, you’ll be able to charge your G5 with the AC adapter as well via a wall outlet. 

The Inogen One G5 External Battery Charger

One of the lesser-known and potentially underrated accessories for the Inogen One G5 is the external battery charger. Typically, in order to charge your G5 batteries, either through AC or DC power supply, you need to have the battery attached to your device. So, if you like to carry more than one battery on you, this accessory will enable you to charge two batteries at once.

Less Downtime

Life can be unpredictable sometimes. One minute, you could be sitting on the couch watching TV and the next you could be rushing out the door to meet with a friend or loved one. While we can’t always predict everything that we’ll do today, tomorrow, or next week, we can do our best to prepare for it.

By being able to charge two batteries at once, the G5 external battery charger will allow you to be prepared no matter what curveballs life throws at you. If you need to jump up and leave the house at a moment’s notice, you’ll have two full batteries to keep you going as opposed to just one.

Convenient and Easy to Use

The G5 external battery charger is very easy to use and can easily be packed with your extra batteries and charging cables when you’re away from home. Weighing in at just 0.85 pounds and about the size of a hockey puck, the external battery charger can easily be placed on a desk or table to charge and can be placed in your G5 backpack or a purse for safekeeping.

This accessory is very easy to use. Simply plug the AC adapter into the wall and into the external battery charger. Take either your G5 single battery or G5 double battery and plug it into the bottom of the external charger. You’ll see a light indicating that the battery is being charged. And once it’s fully charged, the “100%” symbol will illuminate to show you that your battery is fully charged. That’s it! Now you can simply detach the battery and use it on your G5. Remember to use the AC power cable you already own to charge another battery on the G5. That way, you’ll have no downtime.

Backup Oxygen Tubing/Cannulas

Last but certainly not least, it’s a good idea to have some extra cannulas lying around in case you need to replace them. Cannulas are the clear tubes that you attach to the G5 and place in your nose in order to inhale oxygen. Many people don’t know that cannulas come in many different shapes, sizes, and designs, so it’s important to find ones that work best for you and allow you to be comfortable throughout the day.

Cannula Quality

Quality is the most important factor to consider when choosing a nasal cannula or oxygen supply tubing. As you’re moving around and going about your day, low-quality oxygen tubing has a tendency to kink and can even tear if it’s bent out of shape enough. You should make it a habit to check your cannula and tubing regularly to ensure this doesn’t happen, but it’s best to just invest in high-quality nasal cannulas in the first place to avoid this situation.

Tubing Length

Another important thing to consider is the length of the oxygen tubing. Tubing is sold in a variety of lengths like 10 feet, 15 feet, and even longer. Ideally, you’ll want to use shorter tubing because longer tubing can be a tripping hazard and can affect the way oxygen is delivered. When you’re using a pulse flow unit like the Inogen One G5, the device needs to be able to recognize your breaths so it can deliver a precisely timed bolus of oxygen. Most specialists recommend a cannula shorter than 35 feet to ensure the oxygen is being delivered immediately upon inspiration.

Cannula Design

The design of the nasal cannula primarily affects its comfort. There are various types of cannula and depending on your preference, you may choose one over another. Below are the types of cannulas you can choose from.

• Curved prong cannulas
• Flared prong cannulas
• Straight prong cannulas
  
  

You’ll also be able to choose between straight oxygen tubing and coiled oxygen tubing which is great if you want to limit the space your oxygen tubing takes up and it will also make it less of a hazard to you and others. If you need help making your oxygen tubing and cannula more comfortable, we wrote a great article about this a while back. You can find it here.

Conclusion

The Inogen One G5 is a fantastic portable oxygen concentrator. In the short amount of time that it’s been on the market, it’s rapidly become the most sought-after machine due to its reliability, long battery life, and high oxygen output. But we’d be remiss not to mention all the great G5 accessories that help you make the most out of your new device.

The seven accessories we listed above will offer you more freedom in the way that you use your G5 and ensure that you always have access to medical oxygen wherever you go. If you have any questions at all about the Inogen One G5 or G5 accessories, don’t hesitate to reach out to us or stay tuned to our blog for updates on the latest Inogen products.

If you have any questions about what you read here, feel free to leave them in the comment section below or get in touch with one of our respiratory specialists. They will be able to walk you through your options and respond to any questions or concerns you may have about Inogen portable oxygen concentrators.

Inogen One G4 Overview

The Inogen One G4 was released in 2016 to the U.S. market. At this time, it produced more oxygen per pound than any other portable unit and was praised for allowing COPD patients around the world to regain their freedom and independence.

The Inogen One G4 adapted a new design over the G3 which opted for a more sleek and minimalist look. Instead of the sieve beds being visible on the outside of the unit like with the G3, they’re embedded in the front of the unit in one single column. 

Another welcome addition to the G4 was its connectivity. The new Inogen Connect app allowed users to interact with their portable oxygen concentrator via their smartphone or tablet. This app allows people to see their battery life, column condition, and other information without ever having to look at their G4 control panel.

Inogen One G5 Overview

Releasing in the summer of 2019, the Inogen One G5 is the latest and greatest portable oxygen concentrator available from Inogen. Aside from a few minor changes, the look of the G5 remained mostly untouched from the Inogen One G4.  

The most notable improvement with the G5 is that it doubled the oxygen output of the G4. This expanded pulse dose technology significantly and allowed more people to benefit from ultra-lightweight portable oxygen concentrators.

{{cta('fa8abc2a-1e88-4fa3-82fd-1cb5b9ed43b2')}}

Weight

For many people, weight is the single most important factor when it comes to portable oxygen concentrators. With a light portable oxygen concentrator, you’ll be able to go where you want and do what you please without being overburdened or becoming breathless after a few minutes of walking. 

Both the Inogen One G5 and the Inogen One G4 are pulse flow concentrators. What this means is that oxygen is only delivered when the patient inhales as opposed to continuous flow where oxygen is put out persistently. Using this technology, oxygen concentrator manufacturers are able to make smaller devices that still provide you with a reliable source of oxygen.

One of the major selling points for the Inogen One G4 is that it’s the lightest Inogen concentrator ever produced. The only concentrator that has it beat in this category is the AirSep Focus which has less oxygen output and shorter battery life. The Inogen G4 weighs in at just 4 pounds with the single battery which is a half-pound lighter than the G5.

Oxygen Output

Oxygen output is probably the most objective aspect of oxygen concentrators; you’re either getting the oxygen you need to stay healthy, or you need a device that puts out more oxygen. If you need to be on a flow setting of 3 or higher, then the G5 will always be a better unit for you because the G4 only goes up to a setting of 3.

Conversely, if you are in the early stages of COPD and see no reason to have a device that goes up to a setting of 6, then the G3 may be perfect for you. Another thing to note about oxygen output is because the G4 is so light you may not need as much oxygen to feel normal. However, before adjusting your flow setting you need to first speak with your pulmonologist.

One thing you need to take into consideration when deciding between the G5 and G4 is whether or not you will be moving to a higher flow rating anytime in the future. If you already use a setting of 3 and your doctor predicts you may need to move up soon, it would be wise to invest in a unit that can go higher than that.

Size

Size is one factor that you may find important when purchasing a portable oxygen concentrator. Large portable oxygen concentrators and oxygen tanks are not only heavy, but they tend to have awkward shapes as well. For example, oxygen tanks are long and have nozzles on the end that tend to get caught on things like clothing. This makes it difficult to store it anywhere without worrying about it getting damaged.

The G4 and G5, on the other hand, are designed in a way that makes them very easy to carry and store. They’re more box-shaped than many portable oxygen concentrators on the market meaning they don’t take up any more space than they have to. There isn’t anything that protrudes from the device either so you won’t have to worry about it getting caught on anything.

In terms of the actual dimensions, the G4 and G5 are pretty similar, however, the G4 is the lighter of the two units. The G4 is 7.2” H x 5.91” L x 2.68” W and the G5 is 8.15" H x 7.19" L x 3.26" W. That’s not a huge difference, but if you’re looking for the smallest unit possible, the Inogen One G4 is a great machine to go with.

Sound Level

People often come to us and express the concern that their oxygen concentrator will be too loud and that they’re worried about taking it places because it may disturb people. Fortunately, most concentrators on the market are pretty quiet, even continuous flow units, and shouldn’t be a cause for concern. 

The Inogen One G5 rings in at just 38 decibels while the G4 is just two higher than that at 40 decibels on a flow setting of two. Either way, that’s about the sound level of a whisper or a quiet conversation. 

Another thing to take note of is the audible alert system that’s built into both the G4 and the G5. The audible alerts will notify you when your battery is low or if certain parts need replacement. If you are in a public area, you may want to disable this and re-enable it once you’re back home because the alerts may be louder than the actual concentrator.

Battery Life

Because portable oxygen concentrators cannot be plugged into the wall at all times like a home oxygen concentrator, they need a power source to draw from. The quality and longevity of your batteries are important because you don’t want to be out of the house without a way to power your portable oxygen concentrator.

Within the past couple of years, Inogen has put a lot of work into making their batteries more lightweight, efficient, and reliable. The Inogen One G5 double battery can go up to an astounding 13 hours on one charge with a flow setting of 1. That’s a steep incline from the G4’s maximum battery life of just 5 hours on a setting of 1.

FAA Approved

Part of regaining your freedom and independence means being able to fly on a plane again without hassle. Fortunately, you can rest easy knowing that both the Inogen One G5 and the Inogen One G4 are approved by the Federal Aviation Administration (FAA). What this means is that you’ll be able to bring your oxygen concentrator onto the plane as a carry-on item no matter where you are in the world. Due to the size and weight of the G4, you’ll have more options when it comes to storing your device while in flight.

Connectivity

One thing that’s unique to both the Inogen One G4 and Inogen One G5 is their connectivity. Whenever you purchase one of these devices, you will have access to a free smartphone application that connects to your portable oxygen concentrator. This app is called Inogen Connect.

Using the Inogen Connect app, you will be able to get important updates about your POC without ever having to look at it. Below is some of the information you will see:

• Battery status
• Software updates
• cannula and filter maintenance updates
• Column life
• Troubleshooting tips, FAQS, and the user manual
• Oxygen purity status
  
  

There’s no understating how convenient it is to have Inogen Connect. Unlike with other portable oxygen concentrators on the market, you’ll never have to take your user manual with you or remove the device from its carrying case to check its battery status or view other important information.

Most oxygen retailers sell this unit and many of them will repair it or send you replacement parts if you need it. Currently, the G5 offers the highest oxygen output of any pulse flow unit and the longest battery life.  

Conclusion

As you can see, both the Inogen One G4 and the Inogen One G5 are viable portable oxygen concentrators. While the G5 is still the most advanced oxygen concentrator on the market, the G4 still has a lot to offer if you want an extremely small and lightweight unit. At the end of the day, it’s a matter of what your oxygen demands and preferences are.

Personally, we love the Inogen One G5 because it’s proficient or excels at everything it does including battery life, weight, size, oxygen output, and more. As such, we gave it the title, “the best portable oxygen concentrator of 2020.” If you’re still not sure which oxygen concentrator is right for you, be sure to get in touch with us and we’ll walk you through your options.

If you’re someone who wants to get the most out of your electronic devices, you need to keep them in the best condition possible. For example, if you purchase a smartphone, you should do your best to keep the charging port clean, prevent the screen from cracking, and avoid overheating the device.

When it comes to oxygen concentrators, this is no different. From the moment you unbox your Inogen One G5, it’s important to take care of your unit by cleaning it and replacing parts when they’re needed. Unfortunately, many people don’t know what the best practices actually are, so we’re going to help clarify some of the most common concerns people have. 

Keep in mind that each oxygen concentrator is different. What may be great for one concentrator could be detrimental to another. In general, if you have questions about maintaining your device, it’s best to first consult your user manual, and if that doesn’t answer your question, get in touch with the manufacturer or retailer that you purchased it from.

Since the Inogen One G5 is the most advanced and popular portable oxygen concentrator on the market, we figured there would be no better place to start. This portable oxygen concentrator just released this past summer so replacement parts are widely available and it’s old enough that the manufacturers have already dealt with some of its most common issues. 

Weekly Inogen One G5 Maintenance and Cleaning

Many people purchase a portable oxygen concentrator without realizing that they have control over how long their device lasts. There will always be faulty units out there, but those are few and far between and if you have a warranty, you may be able to get a full replacement unit for no added cost.

However, if your oxygen concentrator is working as intended, it’s important to have a clear cut plan that you can follow for cleaning and maintaining it on a weekly basis. Once you get into the routine of taking care of your device, it will become second nature and you shouldn’t have to stress about it.

At the end of the day, cleaning your portable oxygen concentrator will be just as important for your safety as it is for the integrity of your device. Even just wiping your mobile oxygen machine down daily will keep it bacteria-free and ensure that germs don’t spread.

{{cta('b59df0c1-c4de-47a8-8e1c-0d33d4b414aa','justifycenter')}}

Cleaning the Concentrator Case

The case is the hard outer shell of the portable oxygen concentrator. This part of the unit is designed to protect the important electrical components from water, dirt, dust, and grime. While the Inogen One G5 has a very durable and airtight shell, it’s not waterproof and a significant amount of dirt on the device could damage it. What’s more, all Inogen units are white, so if they get dirty, it will show. Follow these tips weekly to clean your Inogen One G5.

What You Will Need:

• A soft washcloth
• A small bowl
• Non-abrasive dish soap
• A dry towel

Steps:

• Unplug your Inogen One G5 from the wall or the cigarette lighter in the car and turn it off by holding the power button on the top of the device.
• Lay the oxygen concentrator on the dry towel with all cords and cannulas removed.
• Take a small bowl and fill it up with warm water and a small amount of non-abrasive dish soap.
• Take a soft washcloth and dip it in the bowl, then wring it out in the sink until the cloth is slightly damp.
• Begin wiping down the outer shell of the Inogen One G5 ensuring that you don’t get water in any of the cracks, especially near the battery at the bottom of the unit.
• Be sure to wipe off the control panel on the top of the unit and the cannula tube because these are the areas you’ll be touching the most and likely contain the most bacteria.
• Once finished, leave the unit in an upright position on the towel to dry before using it again.

Cleaning Your Nasal Cannula

The nasal cannula is the rubber tube that runs from your portable oxygen concentrator to your nose. While most cannulas are well-made and can last for months, they still need to be cleaned regularly to protect both the concentrator and your own health.

Many manufacturers recommend cleaning nasal cannulas weekly, but some people will clean them daily. It’s also recommended that you replace your cannulas every two or three months if you use oxygen therapy on a daily basis. Follow the steps below to clean your nasal cannula.

What You Will Need:

• Soft washcloth
• Clean towel
• Non-abrasive dish soap
• White vinegar
• Cotton swab

Steps: 

• Clean your kitchen sink or bathroom sink with soap and water.
• Fill the sink up with water and add a little bit of the non-abrasive dish soap. Soak the nasal cannula.
• Take the cotton swab and use it to clean dirt and other debris from the nozzle.
• Remove the nasal cannula from the sink and leave it on a dry towel. Drain the water in the sink and rinse it with water.
• Refill the sink with water and add the white vinegar with a ratio of 10 to 1. Add the nasal cannula to the sink and then rinse thoroughly before leaving to dry. The vinegar will help disinfect it and remove any remaining bacteria.
  
  

Cleaning the G5 Particle Filters

There are two types of filter inside your Inogen One G5, one that filters out airborne particles (gross particle filters) and one that filters out nitrogen from the air (sieve beds). Both of these need to be in good condition for your device to work properly.

Particle filters, like the ones found on the Inogen One G5, are really helpful because they provide an additional layer of protection that can help you prevent COPD exacerbations and other respiratory symptoms. By blocking airborne allergens, you’ll be able to breathe pure air and get the most out of your oxygen concentrator.

What You Will Need:

• A soft washcloth
• A small bowl
• Non-abrasive dish soap
• A dry towel

Steps: 

• Turn the Inogen One G5 off by holding the power button on top of the unit.
• Remove the particle filters from the front and back of the unit. To remove them, simply push on the tabs and pull outwards. 
• Take the bowl you set aside and fill it with water and a little bit of non-abrasive dish soap. Place the filters in the bowl to soak.
• Remove the filters from the water and gently wipe them with a dry towel. If there is grime stuck in the corners, use a q-tip to remove it.
• Place the filters on a dry towel then rinse out the bowl. Repeat the same process using clean water in order to rinse them off. 
• Ensure the filter is fully dried before placing it back on the unit.

Long-Term Inogen One G5 Maintenance

The G5 is one of the most reliable portable concentrators on the market. If you follow these weekly cleaning and maintenance tips, your G5 can easily last several years, even if you use it persistently. However, there are several long-term maintenance tips you should be aware of in order to keep your concentrator in great working condition.

Two of the major maintenance concerns you should have with the G5 are the sieve beds and the batteries. G5 batteries are expected to last at least 500 full charge/discharge cycles, and sieve beds (metal columns) are expected to last at least one year.

G5 Column Replacement Procedure

Contrary to popular belief, the Inogen One G5 sieve beds (columns) can be replaced by anyone and you will not have to send it back to the manufacturer or retailer that you bought it from. Unlike with the G3, the columns are not visible on the G5 unit. You’ll need to take the battery off the bottom of the oxygen concentrator to remove your old sieve beds.

Steps:

Removal of Old Columns

• Check to ensure your sieve beds need to be replaced. The control panel on the top of your unit should indicate when the columns need to be replaced. If you’ve used your Inogen One G5 for over a year and there is no alert for you to change it, contact the manufacturer.
• If the device is indicating that you need to replace the sieve bed, ensure that you purchase the correct one. The Inogen One G5 is not compatible with sieve beds of other generations.
• Begin by turning the unit off by pressing the power button.
• Remove the battery from the bottom of the unit by pushing up on the tab and sliding it backward.
• Locate the black panel on the bottom of the G5; these are the sieve beds. Push the tab next to it and raise the metal bar. Slide the column all the way out of the G5.

Installation of New Columns

• Remove the G5 columns from its packaging and remove the dust caps.
• Inspect the columns to ensure there is no dust or debris on it.
• Place the columns in the Inogen One G5 and push until it clicks into place.
• Plug the device into an AC power supply but do not turn the device on.

Checking the Display

• Press and hold the (+) and (-) buttons on the control panel for 5 seconds then press the alert button. 
• Once this icon appears, press the alert button and you should see the following symbol.
• Once complete, reattach your Inogen One G5 battery and press the power button to turn it on.

Note:

If you are using the Inogen Connect app on your phone, navigate to the “Advanced” screen, then click on the “Column Reset” button.

DC Input Cable Fuse Replacement

If you ever charge your Inogen One G5 portable oxygen concentrator in the car via the cigarette lighter, you need to use the DC power plug. This plug contains a fuse that can wear out the more you use it, so if you’re not receiving a charge from a port that you know is working, you may need to replace it entirely.

Steps:

• Unscrew the retainer and remove the tip
• Remove the fuse, tip, and retainer
• Leave the spring inside the cigarette lighter adapter while you insert the replacement fuse
• Install a replacement fuse, Inogen RP#125 (BUSS MDA -12), and put all the components back into place ensuring that the retainer ring is tightened properly.
  
  

Troubleshooting Electrical Issues

Like all other portable oxygen concentrators, the Inogen One G5 is an electronic medical device. In other words, if your device malfunctions, it may be due to a software issue and not just a hardware issue. In general, the G5 has a very simple-to-use interface that shouldn’t offer you too many problems. However, there are several things you should be aware of when it comes to device maintenance.

Performing a Hard Reset on Your Inogen One G5

If you’ve ever encountered an issue with your laptop or desktop computer, you’ve probably been asked, “did you try restarting it?” For many of us, this is the go-to answer for issues with our electronics because it’s so easy to do and works a lot of the time. 

While you can press the power button and then press it again to restart your portable oxygen concentrator, this is not the best way to do it. Think of the power button as a sleep button on a smartphone or other device. While the power button shuts the screen off, it doesn’t necessarily shut down all of the components of the machine. 

A hard reset is designed to completely remove your concentrator from its power source and reboot the system. This is great to try if your control panel is malfunctioning or you’re not receiving oxygen the way you should. Try the steps below and if it doesn’t fix your issue, get in touch with the manufacturer:

Steps:

• Take note of any error codes on the POC’s display
• Remove the battery from the device and unplug it from its AC or DC power supply
• Leave the POC untouched for 30 minutes to reset
• Plug the AC power supply into the concentrator and then into the wall outlet
• Leave the concentrator for another 10 minutes
• Slide the battery back onto the device and check to see if the issue is fixed
• If not, contact the manufacturer and tell them what the issue is and that you tried a hard reset

When Should You Contact a Professional?

Portable oxygen concentrators are an investment. Although they last for years, many people will no longer need them and eventually start looking for a way to sell them. If this does happen, you need your device to be in great condition so that you get the maximum monetary value for it.

If your device stops working for whatever reason or it starts making funny noises, you may be tempted to start taking it apart to figure out what’s wrong with it. However, we strongly advise against this! Attempting to take apart your POC could result in making the issue worse. Rather, you should reach out to the oxygen manufacturer or oxygen retailer that you purchased it from.

Conclusion

The Inogen One G5 is one of the most state-of-the-art portable oxygen concentrators on the market. Although the reliability of the G5 is unmatched, you still need to be prepared to clean it regularly or send it in for repairs when they’re needed. Doing so will ensure that your concentrator lasts as long as possible without needing replacement parts. If you need additional assistance with the steps above, read your Inogen One G5 manual or speak with an oxygen repair specialist.

With so many great oxygen concentrators on the market these days, we can’t blame you for taking the time to find the perfect one. Oxygen concentrator companies like Respironics, ResMed, and Inogen have taken the industry by storm, providing COPD patients with competitive pricing, quality, and efficiency.

Inogen is one company in particular that always seems to stand out whenever someone mentions oxygen concentrators While some concentrator companies choose to focus on units built for in-home use, Inogen believes that portable oxygen machines will offer patients the best experience possible without additional costs.

Another interesting thing to note about Inogen is that their products rarely go out of style. Despite releasing a brand new unit every couple of years, previous iterations remain popular and even compete with their latest models. What this means for you is that you don’t have to worry about purchasing a unit only for it to become obsolete the next day.

Because there are so many things to consider when buying a portable oxygen concentrator, we felt it would be best to break down and compare each Inogen One concentrator to help you find the best one for you. In this post, we’re comparing the Inogen One G5 portable oxygen concentrator and the Inogen One G3 portable oxygen concentrator.

Inogen One G3 Overview

The Inogen One G3 was released back in 2012 with several significant improvements over the Inogen One G2. This included a 25% oxygen output increase over the G2 with no added size or weight, a reduced sound level, and a sleek new design that Inogen would mimic for the next three iterations of the machine.

Perhaps the most notable achievement of the G3, however, is that it aimed to be the most lightweight and powerful portable oxygen concentrator on the market, which it achieved with flying colors. While the Inogen G5 topped the G3 in terms of oxygen output, the G3 still remains a great choice for many COPD patients across the world.

Inogen One G5 Overview

The Inogen G5 was released in the summer of 2019 and is currently the latest Inogen oxygen therapy machine on the market. At first glance, the G5 appears identical to the G4 in that it retains the angular look of the previous iteration. Because the new clean and easy-to-use control interface was so well accepted with the G4, that remained mostly untouched with the G5 as well.

Some of the most notable improvements over the G3 and G4 is that it doubles the oxygen output of the G4, has an increased battery life, and has a reduced sound level. Respiratory patients looking to purchase the latest Inogen model will not be disappointed when they discover the power and reliability of the Inogen One G5.

{{cta('fa8abc2a-1e88-4fa3-82fd-1cb5b9ed43b2','justifycenter')}}

Oxygen Output

Both the G3 and the G5 are pulse flow portable oxygen concentrators. What this means is that instead of oxygen being distributed continuously, the device matches your breathing and only delivers a bolus of oxygen when inhalation is detected. But you may be wondering, “is there a portable continuous flow oxygen concentrator?” The good news is yes, there are portable continuous flow concentrators, but the bad news is that they’re a lot heavier and bulkier than their pulse flow counterparts.

The Inogen G5 offers one additional pulse flow setting than the G3. The G3 can only go up to a 5 whereas the G5 can go up to a 6. If you have mild or moderate COPD, the G3 may work great for you, however, if you have stage 3 or 4 COPD and your doctor recommends a high flow rate, you may need to opt for the Inogen One G5 instead. Below you can see the two units and how they compare to other pulse flow units on the market in terms of total oxygen output.

The G5 also takes the cake when it comes to maximum oxygen output. It can put out 1260 ml of oxygen per minute while the G3 can put out a total of 1050 ml of oxygen per minute.

Weight

The Inogen G5 barely scrapes by with the first place spot for this category. Weight is a very important factor for many people when choosing a portable oxygen concentrator. In the past, the term “portable” had a different meaning for many. Because units were so much bulkier and heavier, it was considered a privilege just to be able to get out of the house. However, nowadays, most people expect to be able to carry their concentrator on their shoulders without becoming fatigued.

The Inogen One G5 weighs in at 4.7 pounds while the G3 weighs in at 4.9 pounds. While this may sound significant, most people won’t even notice the difference unless they’re out and about for an extended period of time. The important thing to note is that they’re both under 5 pounds. That’s about the weight of common household objects and when it’s on your shoulder with a comfortable padded strap, you’ll likely forget it’s even there.

Size

In some ways, the size of the oxygen generator is subjective. Some people may prefer a concentrator that’s tall and skinny or they may prefer one that’s more box-like, but when it comes to two devices with a similar form factor like the G5 and G3, the G5 wins in this category simply because it is smaller in overall size.

The dimensions of the Inogen One G5 are 7.19’’ width x 3.26’’ depth x 8.15’’ height and the dimensions of the G3 are 8.75’’ width x 3’’ depth x 8.25’’ height. As you can see, the differences are somewhat negligible, however, if you know you’re going to be using your POC in a compact area like storing it under a seat or bringing it on an airplane, it might make a difference for you. Conversely, if you want a machine that’s as comfortable as possible on your shoulder, the additional depth on the G5 may be a deal-breaker.  

Sound Level

Many people have concerns about the sounds that portable concentrators make because they don’t want to disturb people if they’re in a church service, in a quiet library or any other crowded area. Fortunately, POCs are designed specifically with these people in mind and the G3 and G5 are no exception. 

The Inogen One G5 is one decibel quieter than the G3 at just 38 decibels. That’s about as loud as a whisper and since these devices make a humming noise, it’s not a sound that will be distracting to you or the people around you. While most people won’t be able to tell a difference between the two devices, it may be something to consider when purchasing a portable oxygen concentrator.

Another thing to be aware of is the audible alerts that are present in these two devices. These alerts will activate to let you know when your battery is low or a part needs replacement. If you find them distracting or disruptive, however, you can turn them off using the control panel.

Battery Life

Battery life is one of the most important factors to consider when purchasing a portable oxygen generator. Many people who purchase the Inogen G5 do so because they know they’re getting the best battery life a POC can offer, however, the Inogen One G3 isn’t too far behind. With the G5 you can get up to 6.5 hours with the single battery and 13 hours with the double battery. With the G3, you’ll get up to 4.5 hours with the single battery and 9.5 hours with the double battery.

The great thing about Inogen batteries is that they’re extremely lightweight. If you think you’re going to need more battery life than what’s offered with the standard single battery, you can always purchase a second one or upgrade to a double battery. Since G3 and G5 are such light units in the first place, carrying an extra battery or two will not be a problem.

Battery Charge Time 

Once you make it back home from the store, visiting a friend, or going on vacation, you want to be able to charge your batteries quickly and reliably. Both G3 and G5 single batteries will go from empty to fully charged in 2 to 4 hours and if you’re interested, you can even purchase an external battery charging. What this means is you’ll be able to charge a battery on your Inogen unit and the external battery charger at the same time.  

FAA Approved

Both the Inogen One G3 oxygen concentrator and Inogen G5 are approved by the Federal Aviation Administration (FAA) for in-flight use. What this means is that if you’re planning a trip across the country or outside the country, you’ll never have to worry about your airline turning you down. Unlike oxygen tanks which are highly pressurized devices, oxygen concentrators have no stored oxygen. What’s more, concentrators are not flammable, bulky, and heavy like oxygen tanks are.

3-Year Warranty

Another benefit of each portable pulse flow oxygen concentrator is that they both offer 3-year warranties. A warranty is a type of protection plan that allows you to replace your unit for free within a certain period of time. Although the processors inside the G3 and G5 are set to last you 20,000 hours of use, you can rest easy knowing you’ll be covered for three years.

You’ll also have the opportunity to upgrade to a lifetime warranty. This is perfect for anyone who has tried an Inogen product in the past and is confident they want to stick with this unit as long as they need it. Inogen lifetime warranties are a great value and provide you with the security you’re looking for in a portable oxygen concentrator.

G3 and G5 Side-by-Side Comparison

Who Should Purchase an Inogen One G3?

The Inogen One G3 is a fantastic unit that has stood the test of time. Despite being nearly a decade old, it still holds up as one of the best units on the market. The best candidate for the Inogen One G3 is someone who wants a high-quality portable oxygen concentrator that’s lightweight, reliable, and has a great battery life. Since it is an old unit, you can expect to see a lot of refurbished portable oxygen concentrators since many patients decided to upgrade to the Inogen One G5.

Another thing to consider is the oxygen output. If you only need to go up to a pulse flow setting of 5, then the G3 will be perfect for you. The G3 provides you plenty of room to grow into without having to pay for any additional features that you don’t need. Whether you’re financing a portable oxygen concentrator, purchasing a refurbished unit, or buying one that’s brand new, you can’t really go wrong with the Inogen One G3.

{{cta('b59df0c1-c4de-47a8-8e1c-0d33d4b414aa','justifycenter')}}

Who Should Purchase an Inogen One G5?

The Inogen One G5 is the most advanced and powerful pulse flow portable oxygen concentrator for sale. With unmatched battery life, oxygen output, and reliability, the G5 is built for people who want the best of the best. Since the G5 was released this past summer, you can rest assured that the unit will be supported for many years to come and if you ever need replacement parts, you won’t have to look far.

Another reason to purchase an Inogen One G5 is if your doctor has prescribed you with a high flow rating of 6. The G5 is one of the only pulse flow concentrators that goes up to a 6, meaning that if you need to upgrade beyond that, you’ll need to opt for a bulkier and less portable continuous flow oxygen concentrator. If cost is not a concern, the G5 is the best portable oxygen concentrator you can get your hands on. And even if you are short on cash, you can always purchase a refurbished unit or put together a flexible financing plan.

Last but certainly not least, the Inogen One G5 has some additional features that aren’t available on the Inogen G3. The G5 comes with a built-in technology called the the Inogen Connect. This was first implemented in the Inogen G4 and allows you to connect your portable oxygen concentrator to your phone, allowing you to see important information such as your battery life, sieve bed life, and device status without ever having to touch your G5. 

Conclusion

Objectively speaking, the Inogen One G5 is the best high-flow portable oxygen concentrator. However, this does not mean that it’s right for everyone. What matters most is that you get a unit that matches your wants and needs without adding any unnecessary costs for you. If the added battery life, reduced weight, and additional features such as the Inogen Connect app are important to you, then the G5 should be your first choice. However, if you can do without these upgrades, the G3 is a great budget unit that offers the same reliability and warranty.

There are plenty of great oxygen concentrators on the market. While Inogen is pushing the boundaries for pulse flow units, there are a host of incredible continuous flow portable oxygen concentrators out there as well such as the SeQual eQuinox and Respironics SimplyGo. Before beginning your search, be sure to discuss with your doctor to learn exactly what amount of oxygen you need and whether or not pulse flow will be an option for you. Once that’s done, give us a call and we’ll help you find the perfect unit for your needs.

Chronic obstructive pulmonary disease (COPD) affects millions of people around the world. It’s a lung disease characterized by difficulty breathing, coughing, wheezing, chest pain, and more. While there is no cure for COPD, its symptoms can be reduced significantly by following a strict treatment plan designed by your doctor. 

In our blog, we’ve discussed many topics about living with COPD such as shopping and cooking, completing household chores, and even living a more fulfilling life. But what about COPD patients who aren’t able to do these daily tasks without help? After all, COPD is a debilitating disease and for many people, doing the things they once could are simply no longer possible — this is where caregivers come in. 

While you may think of a caregiver as someone hired by a home healthcare company, in reality, most caregivers are friends or family members who take time out of their busy day to help a loved one. Oftentimes, caregivers are people who are working full-time or part-time jobs, have kids, a spouse, or other commitments to attend to, so if you’re thinking of taking on the role of a caregiver, you need to be able to manage your time effectively.

Unfortunately, for this type of caregiver, there is no type of training to help prepare you for the task ahead. Being a caregiver means taking things one day at a time and adapting to the needs of your loved one as they age and their condition changes. At the same time, it’s important that you don’t forget the relationship you have with this person. In other words, just because you’re caring for someone doesn’t mean you can’t still be their son, daughter, grand kid, or friend.

In the following sections, we’re going to discuss the importance of caregiving for COPD patients, what you should know to get started, and some helpful tips to manage your time more effectively. It’s important to remember that you’re not alone in becoming a caregiver. According to the COPD Foundation, there are 65 million family caregivers nationwide who spend 20 hours a week on average caring for a loved one, so if you have any questions, consult online forums like AgingCare or speak with a pulmonary specialist.

Getting Started as a Caregiver for COPD

For many people looking to help a friend or loved one through caregiving, knowing where to get started can often be the hardest part. While you want to provide them with the best care you can, you still have your own life to manage, so finding the right balance should always be your first step.

Determine If You’re The Right Fit

One thing you should immediately ask yourself when presented with the prospect of caregiving for someone with COPD is, “Am I the right fit?” While you may be fully capable of taking on the challenge, that doesn’t necessarily mean your busy life will allow it.

Many people have children to raise, jobs to work, or other tasks to attend to, so the more honest you can be to yourself and your loved one about the feasibility of becoming a caregiver, the better. It’s best to find an alternative now rather than realizing three or four months in that you won’t be able to take care of them. Chances are, if it means sacrificing your relationships with friends, family members, or your job security, then finding another option is not out of the question.

Start by reaching out to home care providers in your area. While in-home care can be expensive, you need to consider all your options and remember that many health insurance companies, including Medicare, cover some form of home health services. Depending on your specific needs, it may be covered through either Part A or Part B of Medicare and includes care provided by a home health aide, therapy, and intermittent skilled nursing care.

It’s unlikely that you will get reimbursement from your health insurance if your loved one isn’t homebound, meaning they aren’t able to leave the home without extreme difficulty. Another thing to note is that you will need a signed home health certification from your doctor in order to be covered. If you’d like to learn more about this process, visit Medicare Interactive’s home health services page.

Allocating Your Time

Now that you’ve taken the time to consider hiring a home care provider, you need to start allocating time on your schedule. If you’ve hired a home care professional, you may only need to be there with them for a certain period of time each day. At this point, it’s just about finding this time in your schedule and making sure people are aware that you won’t be available during those times.

Staying organized will make all the difference in the world when you become a caregiver because it will ensure that you’re always prepared for whatever challenges you may face. If you’re organized, you’ll be able to more easily schedule doctors appointments, make yourself available for emergencies, and ensure your loved one is attended to when they need it.

Doing Your Research

Researching COPD is one of the most important steps when preparing to be a caregiver. Generally speaking, the more educated you are about the disease and its unique symptoms, the better prepared you will be to deal with emergencies associated with it. There are two forms of COPD, emphysema and chronic bronchitis.

Emphysema

In the lungs, there are tiny air sacs called alveoli. Oxygen passes through the alveoli walls and enters the bloodstream when you breath. However, in someone with emphysema, these tiny air sacs are damaged and they’re less efficient at transferring oxygen to the blood. This results in symptoms like low blood oxygen levels, shortness of breath, persistent cough, fatigue, and excessive mucus production. 

Chronic Bronchitis

Although chronic bronchitis has similar symptoms to emphysema, it’s a condition that damages the bronchi, the tubes that carry oxygen into the lungs. While the main symptom of emphysema is shortness of breath, the main symptom of chronic bronchitis is a frequent cough, usually accompanied by mucus. Many COPD patients have varying degrees of both these conditions.

Stages of COPD

Aside from the types of COPD, you should also be aware of the stages of COPD. Unlike many other lung conditions, the stages of this disease progress slowly over many years. Although someone with mild COPD may experience very few symptoms, someone with severe COPD can experience symptoms that are much worse and can even be life threatening. 

Stage One

In the first stage of COPD, symptoms are so mild that many cases go undiagnosed. According to lung.org, millions of people may be experiencing the early stages of COPD and not even know it. Symptoms include breathlessness, chronic cough, and fatigue.

Stage Two

In the second stage of COPD, breathlessness, persistent cough, and mucus becomes more pronounced. While symptoms may be debilitating, people often brush them off as a natural part of aging.

Stage Three

By stage three, most people have sought help and realized that they’re dealing with a serious respiratory condition. Stage three is characterized by more difficulty breathing, chronic cough, headaches, fatigue, and increased likelihood of exacerbations. Oxygen therapy is likely needed at this point.

Stage Four

The fourth and final stage of COPD is considered “severe.” Patients in this stage need to follow a strict diet, undergo oxygen therapy and pulmonary rehabilitation. The symptoms include significant difficulty breathing, cardiovascular issues, chest tightness, wheezing, and severe and often life-threatening exacerbations.

These are just a few of the things you should know about each stage of COPD. If you’re going to be a caregiver to someone with COPD, you’ll need to know exactly what stage they are in and what symptoms they are experiencing. If you’d like more details about each stage, please refer to our blog titled: The 4 Stages of COPD: What You Need to Know.

Speak With Their Doctor

Besides doing your own research on COPD, your loved one’s doctor or pulmonary doctor will be your best resource for any type of information regarding his/her disease. When you become a caregiver, you should expect to be the primary point of contact with their doctor because they may be unable to do so. 

Before each doctor’s visit, it’s a good idea to sit down with your loved one and write up a list of questions to ask. It’s much easier to get all your questions answered during your visit than to have to keep calling him or her for information. However, if it’s your first time visiting with the doctor for COPD, you can find a great list of questions to ask in our blog, “16 Questions You Should Ask Your Doctor About COPD.” 

Understanding The Unique Needs of a COPD Patient

Chronic obstructive pulmonary disease is unique in that it can’t be cured, but its symptoms can be significantly reduced with proper treatment. As a caregiver, you have the opportunity to have a significant impact on a patient’s life, not just by performing daily tasks, but by helping them maintain the treatment program set forth by their doctor. What’s more, there are a whole host of home remedies you can try to improve the quality of life of your loved one.

Symptoms and Exacerbations

Before being diagnosed with COPD, many people believe that their symptoms are a natural part of aging. Whether they have emphysema or chronic bronchitis, COPD symptoms are often confused with acute diseases like pneumonia or the common cold. However, when these symptoms last more than a couple weeks, it’s usually a sign that you’re dealing with something more serious. Caregivers need to learn to recognize the symptoms of COPD and COPD exacerbations so they can better treat them or prevent them altogether.

What is an exacerbation?

An exacerbation is a sudden flare up of lung symptoms. Typically, an exacerbation is triggered by either an external factor like air pollution or an internal factor like an infection or virus. So, as a caregiver, you need to make sure you’re doing everything you can to prevent your loved one from getting sick or being in an environment that could cause a COPD exacerbation. In end-stage COPD, exacerbations can be fatal, so they’re often referred to as a “stroke of the lungs.”

What can you do to prevent them?

As a caregiver, there’s a lot you can do to prevent exacerbations. First and foremost, you should understand the signs that an exacerbation is occurring. If you notice any of the following symptoms, you should visit your pulmonologist immediately.

• An increase in frequency or severity of cough
• Increased breathlessness when walking or at rest
• Pain or stiffness in the chest
• Lower blood oxygen levels than normal
• Headaches, lightheadedness, or difficulty sleeping

Avoid getting sick

Acute conditions like the common cold or the flu may be harmless to someone without COPD, but for someone with the disease, it can lead to severe complications and even be fatal. Sickness causes an inflammatory response in the body that can result in increased mucus production, congestion, and more coughing than usual all of which exacerbates COPD issues. If your loved one enjoys spending time with friends and family, take the time to ensure they aren’t near anyone who is sick and if they are, try to schedule their visit for another day.

Eating immune-boosting foods like oranges, yogurt, and ginger is one way to prevent sickness. Since respiration and metabolism are closely linked, maintaining a healthy diet not only prevents sickness, it also keeps a COPD patient feeling more alert, energetic, and ready to take on the day. As a caretaker, it’s a good idea to organize a diet routine for your loved one. However, be sure to speak to their doctor before getting started.

Improve indoor air quality

Many homes have an indoor air quality problem. According to the Environmental Protection Agency (EPA), Americans spend about 90 percent of their time inside where pollutants are concentrated up to five times as much as outdoors. When you’re taking care of someone with COPD, you need to be hyper aware of everything that’s affecting the quality of air inside their home. Try the following to boost indoor air quality.

• Avoid using air fresheners or any cleaning product with artificial fragrances
• Avoid using cleaning products with perchloroethylene, formaldehyde, 2-butoxyethanol, ammonia, sodium hydroxide, or chlorine.
• Vacuum and dust frequently
• Replace HVAC filters and prevent dragging in allergens from outdoors

It’s also important to ensure air quality is safe when you go out of the home. If you live in a busy area, avoid going outside during rush hour or any time air pollution will be at its worst. Seasonal allergies can also cause COPD exacerbations so be sure to avoid any parks or areas with a lot of pollen. There are a lot of trees that give off pollen, so check out a full list here. And if you’d like more information on improving indoor air quality read our blog about this subject. 

Be prepared for an emergency

Beyond preventing sickness and improving indoor air quality, you should always be prepared for an emergency. First of all, you should locate the nearest emergency room and have a list of people to contact in case of an emergency such as their primary care physician and neighbors. While you may not always be able to make it to a loved one in an emergency, there should always be someone close by who can. Be sure to take this into consideration each time you plan a trip as well.

Oxygen Therapy

Many COPD patients are prescribed supplemental oxygen because it’s the most effective means of increasing blood oxygen levels and reducing COPD symptoms. Caregivers should be responsible for ensuring their oxygen tanks or oxygen concentrators are in working condition and that it’s comfortable for the patient.  

Choosing an oxygen device

If your loved one is unable to choose an oxygen device on their own, you may need to help them out. It can be a tricky process narrowing down all your options so you should take your time and speak with an expert. Oxygen therapy devices include oxygen gas, liquid oxygen, and oxygen concentrators. Oxygen gas and liquid oxygen are stored in a tank while oxygen concentrators pull in ambient air and output a more pure, concentrated form of oxygen.

While there are pros and cons to each type of oxygen therapy, portable oxygen concentrators are the most state-of-the-art option. They’re lightweight (usually around 4 or 5 pounds), easy to maintain, and aren’t bulky like oxygen tanks. However, the oxygen device you choose will ultimately depend on the needs of your loved one and the recommendations made by his/her doctor.   

Cleaning and maintenance

Once an oxygen device has been purchased, caretakers should clean and maintain the device. Oxygen tanks need to be refilled when they’re low on oxygen and portable oxygen concentrators have batteries that need to be recharged. Oxygen concentrators also have filters that should be cleaned often and replaced after 6 to 12 months of use. Nasal cannulas should also be cleaned regularly and replaced every couple months.

While most oxygen therapies are reliable, there’s always a chance you could encounter a faulty product. Once you’ve purchased a device, take the time to read the manual and get more acquainted with it so that you’re more equipped to deal with any problem you may encounter. Be sure to jot down the customer service number too so you have someone to contact if you’re away from home.

Ensuring it’s comfortable

Another aspect of oxygen therapy is how comfortable it is for the patient. Some people may have problems with the nasal cannulae, the tubing that runs from the device to the patient’s nose. There are several different types like curved prong cannulas, flared prong cannulas, and straight prong cannulas. While they all do the same thing, your loved one may find that one is more comfortable than another and that one may distribute oxygen better without becoming obstructed in the nasal passage.

Another comfort issue some people encounter with oxygen therapy is dryness in the nose. Since air is constantly being pumped out of the device, it can lead to rashes or irritated skin. This can be fixed by using an oxygen humidifier on your device. These are usually pretty lightweight, portable, and easy to maintain. Many CPAP and BiPAP machines come with humidifiers built into the device. For more information, read our blog titled How to Make Supplemental Oxygen More Comfortable.

Pulmonary Rehabilitation

Pulmonary rehabilitation is the process of improving lung function through simple exercises and techniques. This isn’t something you can do at home, however; you’ll need to see a pulmonary specialist for up to 12 weeks through a pulmonary rehabilitation program. These programs teach COPD patients how their lungs work, evaluate their lung health, and give you practical exercises for improving your lung function. Once this program is complete, the patient will be able to exercise at home more effectively. 

As a caretaker, you should ensure that your loved one is always able to make it to their classes. Typically, they’re only two or three times a week, but it’s important that they make it to each session so that they get the most out of it. Once their classes are over, you can help them create an exercise schedule that will keep them on track. 

Medication

Managing and administering medication is another important part of being a caretaker. Depending on the stage, severity, and other conditions your loved one may be coping with, there are a number of drugs your doctor may prescribe. You should follow these closely and ensure that you only administer the exact amount that the doctor orders. If you need to make any changes for any reason, be sure to consult a doctor first.

Corticosteroids

These drugs are typically administered to people with COPD or asthma and come in either oral or inhaled forms. Corticosteroids have a number of negative risks like high blood pressure, weight gain, and fluid retention, so it’s imperative that you take only the prescribed amount. Since oral corticosteroids affect the whole body, they’re more likely to have these negative side-effects.

Bronchodilators

This type of drug is important for anyone suffering with COPD, asthma, and allergic reactions. A bronchodilator relaxes muscles in the lung helping to clear mucus, reduce inflammation, and make it easier to breathe. 

Other Medication

If your loved one suffers from another condition, your doctor may prescribe you other medication. Many drugs have negative symptoms when they’re used together so you’ll need to be careful and pay attention to what his/her doctor is telling you. If you have any questions or concerns about medications, it’s best to address them sooner rather than later.

Planning Doctor’s Visits

If you thought planning doctor’s visits and organizing medical paperwork was hard when you’re healthy, imagine doing it with a chronic condition like COPD. An easy way to keep track of all of this is to put together a calendar and filing cabinet just for COPD-related paperwork. When you schedule an appointment, mark it on your calendar. During your visit, take notes and store it in your filing cabinet so that you can refer back to it in the future.

Completing Daily Tasks

Another way to help a COPD patient is to complete daily tasks for them unrelated to their condition. Just like anyone else, someone with COPD still has things to get done around the house, errands to run, and people to get in touch with. 

Grocery Shopping

Grocery shopping is no easy task for someone with COPD. Planning a trip to the store can take a lot of time and energy and leave someone feeling breathless and fatigued, especially in the later stages of COPD. As a caregiver, grocery shopping for them is a great way to help out and take a lot of weight off their shoulders. However, if you don’t have time or you’d rather spend it at home helping your loved one, many grocery stores have grocery delivery services that are surprisingly affordable.

Cleaning

We’ve already talked about using safe cleaning products without harmful chemicals, but you should also be helping with organizing and picking up around the house. Organizing their closet, cleaning their dishes, or vacuuming are some simple ways to make your loved one’s life easier and less stressful. Typically, homecare providers won’t clean up around the house so you may need to hire a maid or a friend to help out. 

Cooking

Being around the stove or oven for extended p
