Oxygen therapy has evolved to the point where the oxygen user should not only be getting the oxygen they need to breathe, but the freedom and independence to do more activities, travel, and find happiness in everyday comforts. The demand for oxygen to be user friendly, portable, and noninvasive is hugely due to the fact that every year, about 1.5 million patients in the United States utilize long term oxygen therapy.

However, not every oxygen device can give patients the freedom they deserve. In fact, many oxygen devices tether its user to their home, making travel impossible and exercise unbearable. We are lucky enough to live in an age of innovation and growth, oxygen therapy is no exception. The technology that is used to design and manufacture modern oxygen devices has improved drastically and has come a long way from the heavy and bulky oxygen reservoirs used in the past.

Evolution of Oxygen Devices

Long term oxygen therapy (LTOT) is prescribed to patients with chronic obstructive pulmonary disease (COPD) and other chronic lung diseases. LTOT increases survival and improves the quality of life of users with hypoxia, it can be very dangerous if used incorrectly, which is why oxygen is prescribed to patients by their doctors after taking a series of pulmonary function tests.

In the beginning, pressurized cylinders were the only available option for long term oxygen therapy. Then in 1965, the first home based liquid oxygen system was invented which gave the oxygen user both an immobile and portable oxygen system. This presented a great advantage, where the oxygen user finally had the ability to refill their portable liquid oxygen system and their smaller portable system whenever needed.

In 1973 home oxygen concentrators became readily available, these devices operated by filtering nitrogen from the air and producing medical grade oxygen. Oxygen concentrators provided an unlimited supply of oxygen, and it ran off of electricity. While this oxygen system was safe and efficient it was stationary, and tethered its users to their home where there was electricity.

Today, there are combinations of oxygen devices:

1. Compressed gas canisters
2. Liquid oxygen tanks
3. Concentrators
4. Liquid oxygen portable canisters
5. Battery operated portable oxygen concentrator

Every home oxygen system has a different performance characteristic, with its own set of capabilities and applications. Your doctor should be aware of product variability in performance when identifying specific systems that would work for you.

Your Oxygen Therapy Options

There are so many home oxygen therapy options to choose from that to the point where it is notoriously difficult to know what equipment is right for you, what is available and the capabilities and drawbacks of each device.

So while your doctor will typically prescribe you a flow rate and frequency for home oxygen therapy based on the results of your pulmonary function, the oxygen provider is expected to supply the necessary equipment based on your prescription and recommendations from your doctor. Therefore, it should be evident that it is important to work with the most trustworthy oxygen providers that supply the most trusted names in oxygen manufacturing.

Flow rates

At one point in time, there were only continuous flow oxygen devices, until intermittent-flow devices were introduced in 1983. The continuous flow devices distribute the oxygen at a consistent rate, even while you exhale. Intermitted-flow devices were created to conserve the oxygen that is wasted while exhaling. Intermittent-flow devices only admit oxygen when the user inhales, and it will pause during the exhale.

Both continuous flow devices and intermittent-flow also known as pulse flow devices, are still used today and the flow rate you use will depend on your oxygen requirements that will be established by your doctor. From there it will be the responsibility of your oxygen supplier to adhere to your oxygen requirements and match you with a device that will meet these needs.

There are three main forms of home oxygen therapy that offer both continuous and pulse flow operations listed in the following sections.

Oxygen gas

Oxygen gas can be stored in a portable tank also known as compressed gas systems. You would use a larger stationary concentrator while you are at home, and you would have a smaller oxygen tank that can be taken with you outside the home.

The portable oxygen tanks are very small and only deliver oxygen in pulses, not continuously in order to save oxygen, so you will not run out. This is of course not an option for everyone, because many people do need the continuous flow of oxygen in order to reap the benefits of oxygen therapy.

Liquid oxygen

Liquid oxygen can be stored in a portable tank, but the difference between the gas and liquid oxygen is how the liquid form is more highly concentrated, and more oxygen can fit in a smaller tank. Active people would prefer this method because it is much more portable, but it will still need to be refilled often.

Most people with liquid oxygen and oxygen gas systems are able to get their oxygen delivered to their home, and this will depend on your location.

Portable oxygen concentrators

Portable oxygen concentrators are the most portable option. An oxygen concentrator is a device that takes oxygen from the room, filters out impurities, and concentrates the air into medical-grade oxygen. The most obvious advantages of portable oxygen concentrators is that they are less expensive and don’t require refilling.

So while there are only 3 main forms of oxygen therapy, the diversification between each method is vast, and you may want to read more about the comparison between oxygen device systems, you can do so by clicking here to read Oxygen Concentrators vs. Oxygen Tanks: A Simple Comparison Guide.

A lot like buying a car, the next step, is deciding which brand of POC you will choose and then deciding on the model you want, luckily your choice are limited by your oxygen prescription, but for most people they will have more than one option, and picking the right device can be overwhelming.

Here are 4 other ways to take advantage of your oxygen concentrator

1. Consider buying additional oxygen concentrator batteries.
Having an additional oxygen concentrator battery is extremely important for people who enjoy spending extended time away from their home or car. An extra battery can be the difference between having to worry about leaving an event early versus living stress free knowing you have plenty of time with pure medical grade oxygen. This particularly applies to patients who do not get as much battery life, either due to their high-flow rate, or their device just doesn't have that long lasting battery that some do.

2. Keep your spare batteries fully charged and do not forget to rotate them.
Keeping an extra battery without a charge for extended periods of time can actually damage the battery. Oxygen users should always store spare batteries that are fully charged. this is not only better for the battery life overall, but keeping batteries fully charged and ready, allows you to switch batteries at any time without having to worry about damaging them or your POC. You should also rotate batteries if you have more than two and always switch to a fully charged battery.

Tip: If you aren't going to use your spare batteries, store them at a 50% charge to ensure you don't damage any battery cells.

3. Utilize the accessory bag that comes with the package

Most units will come with a custom carrying case, few do not. Theses accessory bag vary in size and color based on the type of concentrator you have has. The accessory bag is an excellent organizational tool that helps you arrange the unit accessories in one particular location without having trouble finding them or risk losing them. Accessory bags usually have padding, zipper or velcro, and easy access to keep the contents safe. 

4. Utilize the DC Power Supply.
All POCs come with a DC power supply that can be plugged into the cigarette lighter of a car. Small pulse flow units are totally functional on the DC power supply, which means you can use your device on any flow rate settings, and recharge the battery at the same time. However, the constant flow units carry a few limitations when using the DC power supply. Generally, uninterrupted flow units will continue to work and charge on pulse flow settings 1-4 as well as continuous flow settings as much as 2 LPM.
