In this article we are looking at three generations of Inogen oxygen devices, the One G3, G4, and G5. All of these devices offer the quality and reliability that you need to feel confident and covered at all times. 

Quality Oxygen Equipment 

Chronic obstructive pulmonary disease (COPD) is one of the leading respiratory diseases in the world in terms of morbidity and mortality. Around 65 million people have it, and many experts are expecting that number to grow over the next 50 years. One thing that’s unique about COPD is the fact that it develops very slowly over the course of many years. Because of this, many COPD patients are susceptible to complications that are as bad, or even worse than their underlying condition.

One of the most notable examples of this which often occurs in the later stages of COPD is heart disease. Since the heart and lungs work together to distribute oxygen throughout the body, impaired lung function can result in added strain on the heart. Over time this can cause serious complications like right-sided heart failure, heart attacks, and coronary artery disease.

Fortunately, studies have shown that — by proactively managing your respiratory symptoms — you’ll significantly reduce your risk of experiencing complications from COPD. Treatments like oxygen therapy will reduce the workload on your heart and lungs and ensure that every organ in your body has the oxygen it needs to function properly. However, it’s still important to understand the complications of COPD so that you know what symptoms to look out for.

In the following sections, we’ll take a look at one of the lesser discussed COPD complications called pneumothorax, also known as a collapsed lung. If you have any questions about the content of this article, please address them in the comment section below. However, if you have questions about your COPD or treatment plan be sure to consult with your doctor. COPD is a complex disease, so something that works for one person may not work for another.

What is Pneumothorax?

“Pneumothorax” is the medical term used to describe a collapsed lung. This occurs when air enters the “pleural space” which is the area around your lungs. This disrupts the balance of pressure between the inside and outside of your lungs and can result in a collapse of the lung. Pneumothorax ranges in severity from mild to life-threatening. Mild pneumothorax often needs no medical attention and will heal over time.

What Types of Pneumothorax Are There?

There are two basic types of pneumothorax: traumatic and nontraumatic. Traumatic pneumothorax is caused by physical injuries such as a fall, car accident, or any other type of injury that damages the chest or lung wall. Nontraumatic pneumothorax is also called spontaneous pneumothorax because it occurs without injury. There are many different factors that can contribute to or cause the onset of non-traumatic pneumothorax and it tends to be more difficult to understand than its counterpart.

There seem to be two separate instances where non-traumatic pneumothorax occurs and as a result, researchers have created two different classifications: primary and secondary spontaneous pneumothorax. Primary spontaneous pneumothorax (PSP) is more common in younger adults with no lung disease and secondary spontaneous pneumothorax (SSP) is more common in older adults with lung conditions.

One final classification that should be mentioned is spontaneous hemopneumothorax (SHP). This is an extremely rare but serious condition where both air and blood fill the pleural cavity, usually in patients who have no known history of chronic lung disease.

What Are the Symptoms of Pneumothorax?

Symptoms of pneumothorax vary based on what is causing the condition. Since pneumothorax can develop very slowly this may cause someone to underestimate the risk. However, in certain situations, it can develop very quickly causing someone to immediately seek medical attention. In mild cases, you may not experience any symptoms at all or at least not enough to cause you any concern. Below are some possible symptoms of pneumothorax:

• Dyspnea - shortness of breath
• Tachycardia - a fast heart rate
• Chest pain
• Cyanosis - a bluish discoloration of the skin
• Tightness in the chest
  
  

Causes and Risk Factors of Pneumothorax

Causes:

Mechanical ventilation - Mechanical ventilation is a medical procedure that’s used to assist someone with breathing if they are undergoing surgery or they have a medical condition that is preventing their lungs from working. While ventilation is mostly a safe procedure, if it is administered incorrectly and there is an imbalance of pressure within the chest, it can cause the lungs to completely collapse. 

Ruptured air blisters - Small blisters called blebs can form on the top of the lungs in people with damaged lung tissue. Over time, these blisters can burst, allowing air into the pleural space. This can put a lot of pressure on the lungs and cause them to collapse.

Chest injury - Chest injury is a very common cause of pneumothorax. Blunt or penetrating injuries can occur during car accidents, sports injuries, or falls. Chest injury can also occur during lung surgery or it can be caused by collateral damage from other types of surgery.

Risk Factors:

Age - Pneumothorax is more likely to occur in young people between the ages of 20 and 40 or older adults with chronic lung conditions.

Gender - Tall underweight men are more likely to contract pneumothorax.

Smoking - Risk of pneumothorax increases with time and the number of cigarettes smoked.

Lung disease - Having a chronic lung condition like COPD, asthma, or cystic fibrosis puts you at a higher risk of pneumothorax.

Genetics - Studies have shown that mutations in the FLCN gene can cause pneumothorax.

Medical history - People who have experienced pneumothorax in the past are more likely to experience it again.

Why is COPD a Risk Factor for Pneumothorax?

The term chronic obstructive pulmonary disease (COPD) is an umbrella term used to describe two different diseases: chronic bronchitis and emphysema. Chronic bronchitis is characterized by inflammation in the bronchioles (bronchial tubes) which are the airways that lead to the lungs. Emphysema causes the alveoli (tiny air sacs in the lungs) to fill with fluid and impair the transfer of oxygen and carbon dioxide to and from the bloodstream.

One of the main reasons that COPD contributes to pneumothorax is because of the inflammation and damage that occurs to the lungs. While on the surface it may seem like COPD is a simple condition, it’s actually very complex and it affects the respiratory system in more ways than one. One thing that emphysema causes in particular are a change in the structure of the lungs. As the alveoli in the lungs start to break down, they lose their elasticity making it much more likely for air pockets to form in the pleural space.

Bullous emphysema results when fluid-filled sacs begin to form in the lungs. Bullae usually form in the upper lobes of the lungs and lung function can be significantly impaired if they become inflamed or rupture. This also weakens the overall structure of the lungs putting you at a higher risk of experiencing pneumothorax and other related issues.

In some cases, emphysema patients are a candidate for lung volume reduction surgery. While it may sound counterintuitive to reduce the size of the lungs of someone who can’t breathe well, this surgery is designed to remove only the diseased tissue. In other words, the surgeon will remove tissue that has lost its elasticity or isn’t able to transfer oxygen to the blood. This prevents the lungs from trapping air and allows you to breathe much easier.

Unfortunately, lung surgery can also be the cause of pneumothorax, especially if it involves a highly invasive procedure like lung volume reduction surgery. Before you decide that surgery is the best procedure for treating your emphysema, be sure to speak with your doctor about the risk of pneumothorax and ask any questions if you have them.

What Do COPD Patients Need to Do to Prevent Pneumothorax?

Schedule Regular Checkups

Probably the best thing you can do to prevent pneumothorax as a COPD patient is to see your doctor regularly. As aforementioned, pneumothorax isn’t always a condition that progresses quickly. In some cases, it can progress slowly and heal on its own. But to give yourself the best chance possible to recover quickly and effectively, you need to be aware of what’s causing it. Visiting your doctor regularly will give you a chance to discuss your symptoms and learn about your condition.

Follow Your Treatment Regime

There’s no doubt about it, you have a lot to worry about as a COPD patient. COPD treatment regimes usually involve a lot of different lifestyle changes like oxygen therapy, pulmonary rehabilitation, a revised diet, and an improved sleep schedule. While it’s not easy following all of these things to a tee, it’s worth it if you want to minimize your risk for common COPD complications like pneumothorax.

Quit Smoking Immediately

Smoking is the primary cause of COPD and it’s also one of the biggest risk factors for pneumothorax. So, it goes without saying that immediate smoking cessation will be hugely beneficial if you’re concerned about this complication. Smoking has been proven to increase the likelihood that a bleb will rupture which leads to air building up in the pleural space which collapses the lung.

Have an Action Plan

Another thing you can do is to simply have a plan in place in the event that you experience serious symptoms. Considering the fact that COPD exacerbations are a common occurrence you should already have an emergency plan in place. One thing you should do right away is to install a medical alert system in your home. The medical alert system comes with a small pendant that you wear around your neck. If you experience a medical emergency, simply press the button and an ambulance will be sent to your home. 

How is Pneumothorax Treated?

Observation

The first thing your doctor will likely do if he/she suspects you have pneumothorax is to test for and observe your lungs. Chest X-rays and computerized tomography (CT) are the two most common tests used to detect but ultrasound imaging can also be used to get a better look at the lungs. If these tests reveal that you have a pneumothorax, your doctor may continue to observe it over the course of several weeks or months if it’s not urgent.  

Needle Aspiration

This is one common treatment option for pneumothorax where a special needle is inserted into the pleural area. This needle extracts air so that the lungs can begin to re-expand and you can breathe normally again. Typically the needle is left in for several hours to ensure that all of the excess air is removed. A similar procedure is done by inserting a tube into the pleural space instead of a needle.

Nonsurgical Repair

If the above methods don’t work, there are several non-surgical options that your doctor might try. Bronchoscopy is a procedure that’s commonly used to examine the lungs and diagnose lung conditions, but in pneumothorax patients, it can be used to place a one-way valve in the affected area of the lungs. This will allow air into the lungs but prevent it from going back into the pleural area, thus re-expanding the lungs.

Surgery

If all other treatment options are exhausted, a medical specialist may resort to surgery in order to repair your pneumothorax. The specific type of surgery used to treat pneumothorax is called video-assisted thoracic surgery (VATS) or thoracoscopy. There are two other surgeries that can be done at the same time to prevent the resurgence of pneumothorax. These procedures are pleurodesis and bleb resection.  

Pleural abrasion is one of the most common types of pleurodesis and it involves applying a special chemical designed to seal up the area of the lung that is leaking. Another way this can be done is by extracting blood from another area of the body and using this as a type of sealant to repair the leak. This is referred to as an autologous blood patch.

Conclusion  

Pneumothorax, or a collapsed lung, is a scary thought regardless of whether you are a COPD patient or someone who’s otherwise healthy. In some cases, pneumothorax can be harmless and will heal itself over time. But in other cases, it can be life-threatening and require immediate emergency medical attention. Unfortunately, pneumothorax shares many symptoms in common with COPD exacerbations so it’s best to see your doctor any time that you experience a flare-up in your symptoms.

Here at LPT Medical, we are serious about providing COPD patients with reliable portable oxygen devices. While oxygen therapy will not prevent pneumothorax, it will ensure that you are able to use supplemental oxygen therapy wherever you go and reduce your risk of experiencing severe side-effects of COPD. Portable oxygen concentrators like the Caire FreeStyle Comfort and Inogen One G5 are our most popular units, but we offer many other options as well including pulse dose portable oxygen concentrators, continuous flow portable oxygen concentrators, and stationary oxygen concentrators.

Oxygen therapy is a life saving therapy that helps oxygen patients around the world treat respiratory diseases like chronic obstructive pulmonary disease or COPD. Oxygen therapy is most commonly administered through nasal tubing called oxygen cannulas or with a face mask if you are using oxygen at night time while you sleep. 

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

There are many ways to treat COPD, but oxygen therapy is the only treatment that has been proven to prolong life in hypoxic patients.

If you use oxygen therapy you probably have a liquid oxygen tank, a gas oxygen tank, or a portable oxygen concentrator, all of these devices will supply you with oxygen, however a portable oxygen concentrator (POC) is the easiest-to-use solution for better breathing. 

In this blog you will be able to compare different solutions for your oxygen therapy needs, and specifically how Inogen oxygen devices compare to other oxygen therapy devices. 

How Inogen Oxygen Devices Work 

All oxygen devices push oxygen through tubing that connects to your nose so that you can breathe in the extra oxygen to treat the hypoxia caused by your disease. Portable oxygen concentrators operate very differently than an oxygen tank. Rather than getting your oxygen tank refiled every week, you simply charge the batteries. 

Here is how Inogen systems work: 

Purifies Air continuously

Similar to an air filter that you can leave in your home, your portable oxygen concentrator filters out impurities in the air before you breathe in the oxygen it is providing you. Inogen systems including the One G3, One G4, and One G5 all come with great filters that will extract particles from the air to ensure you are getting medical grade oxygen. Your filter should be replaced depending on how often you have to use your device, it is very easy to replace your own filter. 

For example if you have the One G4, you can order a One G4 air filter, simply purchasing a new filter from LPT Medical, and calling 1(800)-946-1201.

By changing your filter when it becomes misshapen or when the screen is damaged the filters keep dust, pet hair, and other air-borne contaminants out of your oxygen.

The Inogen filters are washable and reusable so you don't have to continuously buy new ones. The best practice is to wash and dry your filters weekly, and if you use your device more often in very dusty environments, you can even clean it twice a week to help keep your concentrator working properly.

Removes Nitrogen to Deliver Oxygen-Rich Air

The air surrounding you that you breathe everyday is made up of 80% nitrogen and 20% oxygen. This level of nitrogen is not an issue for healthy people who have normal levels of oxygen in their blood. With your low levels of oxygen in your blood you will struggle with converting the nitrogen filled air into the pure oxygen your body needs. 

This is why it is important for your oxygen device to take regular air and purify it to be 90-95% oxygen, with limited amounts of nitrogen.

{{cta('43b79c5e-6bd6-4f02-ac27-2d038d20c146','justifycenter')}}

To remove nitrogen from the oxygen you breathe you inogen oxygen concentrators goes through these three steps:

1. Uses a compressor that moves air into sieve bed filters to remove the nitrogen
2. Distributes the purified oxygen through hoses inserted into the nostrils
3. The nitrogen is later released back into the air

Delivers Purified Oxygen Via Nasal Cannula

The nasal cannula is tubing that is attached to the oxygen device, and wraps around your head and the tubes are inserted into your nose. It is essentially a thin, plastic tube that has two small prongs at one end that rest in your nostrils.

The nasal cannula can comfortably deliver oxygen to a you at a setting of one to six liters per minute (LPM), but if you are breathing through your mouth it is possible you are not getting enough oxygen.

A study by PubMed concluded that, while mouth breathing doesn't always result in hypoxia, it can contribute to it.

If you are a mouth breather and need supplemental oxygen it could be very beneficial to learn how to breathe through your nose. 

Mouth Breathing with Oxygen Therapy  

To address your mouth breathing, first try to figure out the cause, and what exactly is making you breath out of your mouth rather than your nose. Once you have accurately diagnosed this, you can address the treatment options which may include the following:

Clear Your Nasal Passages

You could be breathing through your mouth because your nasal passages are blocked. A stuffy nose could be attributed to seasonal allergies, illness, prior trauma, or even weather changes. 

Over-the-counter antihistamines are available to reduce your allergy and cold symptoms and for a brief time, and open up your clogged nasal passages. 

Saline nasal spray is another option you have to lubricate your nasal passages and relieve congestion.

Go to the Dentist

Dentists can sometimes offer you more insight into why you are mouth breathing. It could be that a facial or dental abnormality is the cause of your mouth breathing and in this case they may fit you with a functional device to help correct the problem.

Switch from a Nasal Cannula to a Face Mask

The easiest solution to getting enough supplemental oxygen as a mouth breather, if deemed medically appropriate, is to switch to a face mask. Unfortunately, this is much more invasive for many people and must first be approved by your oxygen-prescribing healthcare provider. 

Another option is to consider using the nasal cannula during the day while you are out doing things, and switching to a mouth covering face mask at night. This way you are getting the full benefit of oxygen therapy while you are asleep. 

Talk to your doctor about these alternatives to the nasal cannula.

Nasal Surgery

If you have a deviated septum your nasal passages are blocked all the time and you should consider talking to an Ear, Nose, and Throat (ENT) specialist about the surgery that may help correct the problem and allow you to breathe better. 

Remember anesthesia can cause postoperative complications if you have COPD, so be aware of these risks before undergoing surgery.

Pulse Oximetry for Those on Supplemental Oxygen

Despite your oxygen therapy method or device, having a pulse oximetry monitor is essential for anyone who receives oxygen therapy. Pulse oximeters can detect rapid changes in your oxygen saturation levels so that you are warned that you're low on oxygen. Knowing your oxygen saturation levels is a huge benefit and helps you treat you disease to the best of your ability

Powered by Rechargeable Battery and any AC or DC Power Source

The most notable difference between traditional oxygen tanks and Inogen brand devices is how Inogen oxygen systems are all powered by rechargeable lithium ion batteries.

Having an oxygen device that will never run low on oxygen means a number of things. First, you will never wait around for your oxygen to be delivered, nor will you have to worry about paying for your new oxygen tanks every week. 

Instead, you can recharge your battery day or night, while you are using your device, in the car or on the move with an external battery charger. 

You have the option to go with the smaller 8-cell battery or buy a larger 16 cell battery when you order an Inogen One G3 One G4, or One G5. The 16-cell battery lasts longer, and it is just slightly heavier. 

The 8-cell battery is no additional cost and comes with the purchase of any Inogen oxygen concentrator when you purchase from LPT Medical at 1(800)-946-1201! 

With a battery powered device you have the ability to take your oxygen system on a plane with you and travel to your destination stress free. You will no longer have to rent oxygen and spend valuable time and money finding a palace to rent oxygen while you are away from home. 

Read our blog about traveling with your supplemental oxygen in 2021.

Out of all of the Inogen systems, our best selling device is the Inogen One G5, and here is why:

Inogen One G5 

The Inogen One G5, is the most advanced Inogen system so far, it has six pulse flow settings— The amount of oxygen the One G5 can administer while maintaining the compact and lightweight design in comparison to the earlier generations is outstanding. This extra level of oxygen output gives more people who use oxygen therapy the ability to take advantage of lightweight portable oxygen devices. 

If you have a lower flow of oxygen you may not see this as an immediate benefit, however having the option to increase your oxygen output is always better. As ailments worsen or your condition progresses, you may need to increase your oxygen output.

For example, if you have a chronic lung condition like COPD  your prescription may be suited to a three-level flow setting, but your need for oxygenation could increase to a six while exercising, or in the case of an emergency while you are experiencing a COPD exacerbation. 

One common issue you might have with oxygen concentrators in the past is their noise, which can be loud enough to impact a good night’s sleep. However, Inogen has improved upon their previous models, and the One G5 is only 38 decibels while on a level two setting, which is quieter than other Inogen One units. 

38 decibels is rated as a soft sound, and typically it will not impede on your day-to-day activities, and it may just help you sleep a little better.

The One G5 unit weighs less than five pounds, which for some people may actually be too heavy to carry around all day, and that is why it comes with a One G5 custom carrying case, and you have the option to buy a One G5 backpack. The backpack can hold extra items when you are out running errands or playing a round of golf! 

The One G5 also offers an amazing battery; you’ll have the option to get an 8-cell battery or a 16-cell battery. With the 16-cell battery on a setting 3 you will have power in your device for 7 hours! It is not only a great portable unit to carry around all day but it is also Federal Aviation Administration (FAA) approved meaning that it’s an excellent option if you are  eager to travel.

Overview

It is clear why Inogen oxygen devices are so popular, they work well and for many different kinds of oxygen patients, but they are also durable and last a long time.

If you are interested in learning which generation of Inogen One concentrators will work better for you and within your budget, give LPT Medical a call, and our respiratory specialists will help you, and work with your doctor to find the right oxygen device for you.

• Particle Filter

The Lightest weight Portable Oxygen Concentrator Available 

The One G4 weighs 2.8 pounds and stands at 7.2” H x 5.91” L x 2.68” W, meaning that the G4 is the smallest and lightest portable oxygen concentrator to offer pulse flow settings 1-3.

The small size and light weight makes the Inogen One G4 perfect for any occasion, and you don't have to worry about using it everyday because Its compressor is rated to last 20,000 hours. 

It’s small enough to carry virtually anywhere without physical strain to you or your body. The One G4 is the perfect travel companion, you can go by foot, plane, boat, car, etc. it has never been easier to be on the move with oxygen than it is with the G4.

You will receive a padded shoulder strap with the purchase of your One G4. This will help you be comfortable carrying your Inogen One G4 to the doctors, through the airport, or at the store. And at 2.8 pounds, you will use very little energy to carry your oxygen with you!

Great Battery Life 

One of the biggest perks of owning a portable oxygen concentrator in general, is having an oxygen device that runs on battery power. Portable oxygen concentrator will utilize the air surrounding the device so you never run out rather than a finite amount of oxygen that would come in a tank or reservoir. 

A rechargeable lithium-ion battery give you peace of mind because as long as your device is charged, you will have oxygen, and there is no more waiting around for your tanks to be refilled or replaced. 

The battery is what adds the real weight to any portable oxygen concentrators, so the bigger the battery the heavier the device will be. If the oxygen device requires a lot of energy, as a continuous flow portable oxygen concentrator does, the battery must be bigger and the device will be heavier. 

So the 2.8 pound One G4 has a relatively small battery compared to the Respironics SimplyGo which is the lightest weight continuous flow portable oxygen concentrator, however the battery life is surprisingly good for how small this machine is!

Being less restrictive with its oxygen settings and by giving you up to 5 hours of battery life, the Inogen One G4 set the bar high for competitors to follow.

The One G4 is compatible with two different batteries, a single battery and a double battery. The Single battery weighs less than the double battery, but it does not last as long. 

With the single battery, you can get up to 2.25 hours of use on a single charge on a setting of 2 and your Inogen One G4 will weigh just 2.8 pounds. This setup is perfect for making trips to the doctor’s office, running to the store, doing things around your house, and exercising.

{{cta('43b79c5e-6bd6-4f02-ac27-2d038d20c146','justifycenter')}}

The double battery, on the other hand, gets up to 4.5 hours of use on a single charge. Despite doubling your battery life your Inogen One G4 will weigh a mere 3.3 pounds with the double battery installed. This setup will give you the freedom and independence to travel, go to sporting events, or get dinner and see a movie.

Pulse Flow Oxygen Output

Oxygen output is the most important aspect of your portable oxygen concentrator. Your oxygen device must be able to give you the amount of oxygen you need to maintain healthy oxygen levels day and night. Oxygen flow is measured in liters or milliliters per minute. 

Here are the flow setting options you have with the One G4, the One G4 only offers pulse flow operation. 

Flow Setting Oxygen Output (milliliters per minute)

Setting 1:  210 ml/min

Setting 2: 420 ml/min

Setting3: 630 ml/min

Approved for Nighttime Use

Even though the Inogen One G4 is a pulse flow portable oxygen concentrator it is still approved for nighttime use while you sleep because it is equipped with Intelligent Delivery Technology. Now, the G4 won’t work for everyone at night, but as long as you don’t require a CPAP or BiPAP machine to sleep it should work for you!

Inogen’s Intelligent Delivery Technology is more sensitive when detecting your breath and it is more efficient at delivering your oxygen to ensure minimal amounts of your oxygen get wasted.

Here’s how Inogen’s Intelligent Delivery Technology works:

To make suer that you get all of the oxygen you require and the oxygen is not wasted, Intelligent Delivery Technology delivers your oxygen within the first 400 milliseconds after your G4 detects your breath. This almost guarantees that you are receiving the full bolus dose of oxygen.

When you sleep, breathing rate slows so the Intelligent Delivery Technology monitors your breath rate and it will increase or decrease the amount of oxygen in each bolus dose depending on your breath rate and the oxygen setting you are using.

This guarantees you are getting your required oxygen!

If you aren’t sure if the Inogen One G4 will work for you at night, you can always speak with your doctor about it or get a sleep test to make sure before you try it yourself.

Easy to Operate

Just like the other Inogen concentrators, the Inogen One G4 is simple and easy to use. The control panel is equipped with a backlit LCD screen and large push buttons.

The backlit LCD screen is easy to read in direct sunlight or in the dark. It displays vital information like your flow rate, your remaining battery life, and it will notify you if anything is wrong with your concentrator. And the font is large and easy to read so you won’t have to squint to see what it says.

Operating your G4 is simple. The control panel only has 4 push buttons:

Power Button (standard power symbol)

Flow Rate Up Button (plus sign)

Flow Rate Down Button (minus sign)

Audible Alarm Button (bell)

Changing batteries on your G4 is quick and easy too! The G4 batteries are equipped with easy push-to-release tabs that allow you to change your battery in seconds. And you won’t have any difficulty getting your replacement battery installed. To make the process as easy as possible, Inogen engineered the battery slot to have a track that ensures your battery perfectly aligns with your concentrator.

Three ways to Charge the Batteries

Recharging your Inogen One G4 batteries is fast and convenient. You have a total of three different charging options to choose from:

1. AC Power Supply
2. DC Power Supply
3. External Battery Charger

The AC power supply is the most common charging option. It charges your batteries faster than the DC power supply and you can use your Inogen One G4 on all 3 oxygen settings while you recharge. The AC power supply is equipped with a 110v power cord allowing you to plug it into any wall outlet. You can use it at home, in your hotel room, on a cruise ship and even some of the newer airplanes have 110v outlets at every seat.

While your Inogen One G4 is plugged into the AC power supply you will have an unlimited amount of oxygen. So, make sure you plug your G4 into the AC power supply if you plan on using it to sleep.

The DC power supply gives you the ability to power your concentrator and recharge your batteries on the go! It is equipped with a 12v power cord so you can plug it into the cigarette lighter or 12v outlet in your vehicle. You can take it in your car, truck, RV, or on your boat!

While your Inogen One G4 is plugged into the DC power supply it will recharge and supply you with oxygen on all 3 settings. However, if you are using your G4 while it is plugged into the DC power supply it will take longer to recharge. Remember to turn your vehicle on before plugging your G4 into the DC power supply otherwise, you might blow a fuse or drain your vehicle’s battery.

Although the external battery charger is an optional accessory, it is the most convenient charging option available for your Inogen One G4. It’s a single bay charger that gives you the ability to recharge your extra batteries without plugging your concentrator into a power supply. This means you can run errands, exercise, or go visit your friends and come home to a fully charged battery waiting for you!

Overview 

The Inogen One G4 is a great oxygen device if you need anywhere from 210 - 630 ml/min of oxygen during the day and/or night, and if you want a device that has great battery life!

If you have any questions about what you will receive with the One G4 or how to work this device, simply call 1(800)-946-1201, so a respiratory specialist may help you!
