Learn About Portable Oxygen Concentrators

A portable oxygen concentrator is one incredible piece of equipment. Not only can it provide you with the amount of oxygen you need, without the use of any oxygen tanks, it's also a smart device that is capable of detecting when you are taking a breath, and will work to make sure it meets your individual oxygen needs. There are so many different features, but many of these necessary features are present in most portable oxygen concentrators.

The sole purpose of a portable oxygen concentrator is to give you the oxygen you need, while allowing you to go virtually wherever you want or need to go. All of our portable oxygen concentrators are approved by the Federal Aviation Administration. This means you can use them aboard any large passenger airplane, which is traveling to or from United States soil.

This allows you the freedom you want and need, while getting the oxygen therapy you need. Along with a portable oxygen concentrator that can deliver the dosage of oxygen you need, you will also need the carry bag, mobile cart, which comes with some of the heavier portable models, one or more batteries or supplemental battery backs for more battery life on the go, and other accessories.

Summary Portable Oxygen Concentrators

A portable oxygen concentrator, also called a portable concentrator is a portable device used to provide oxygen therapy to a patient at substantially higher concentrations than the levels of ambient air. It is very similar to a Portableoxygen concentrator, but it smaller in size and more mobile. The portable oxygen concentrator makes it easy for patients to travel freely; they are small enough to fit in a car and most of the major concentrators are now FAA approved.

Size of Portable Concentrators

While some portable oxygen concentrators are very small - think around 5 lbs - others are larger in a mid-sized range - around 10 lbs - and others are around 20 lbs. This variation in size depends mostly on how much oxygen its capable of delivering, in LPM (liters per minute) for continuous flow oxygen, and ml per minute, such as the pulse dose settings. Some portable oxygen concentrators have both continuous flow and pulse dose settings, such as the SeQual Eclipse 5, while others only deliver pulse dose oxygen, such as the Respirionics EverGo.

Some of the very small concentrators do not have a battery that can be taken out and put back in, but you can supplement their battery life with a battery pack, which you can wear like a belt, such as the case with the small AirSep portable models, the AirSep Freestyle, Freestyle 5 and the AirSep Focus.

Battery Life of Portable Units

Some of the larger portable concentrators that accommodate a rechargeable battery, have an external battery charger, which can be used to charge a second battery while the other battery is running and/or charging the concentrator. This is a very handy accessory for saving time, especially when you are busy and traveling or on the go.

Controls and Usability

Portable oxygen concentrators are easy to operate, with control panels that are easy to read. Some come with screens that light up, while others do not. They all have safety features such as alarms that go off for issues such as low oxygen flow, overheating, etc.


Portable oxygen concentrators are also durable, and designed to withstand heat, cold and humidity to a certain point. The maximum operating temperature for many of our portable models is 104 degrees Fahrenheit, and the minimum operating temperature is 45 degrees.

Development of Portable Concentrators

Portable oxygen concentrators have been around for decades; but the older versions were bulky, not reliable and not FAA approved. Since 2000, a number of manufactures have introduced the latest and more reliable versions of the portable oxygen concentrators. They produce anywhere between 1 and 6 liters per minute (LPM) of oxygen. There are versions that are pulse-flow or continuous-flow. The portable concentrators plug directly into a regular house outlet for charging at home or hotel; but they came with a power adapter that can usually be plugged into a vehicle DC adapter. They have the ability to operate from the battery power as well for either ambulatory use, or away from a power source, or on an airplane. The FAA has approved the use of portable oxygen concentrator for use on commercial airlines. This Special Federal Aviation Regulation (SFAR) will permit passengers to use certain portable oxygen concentrator (POC) devices on aircraft, provided certain conditions in this SFAR are satisfied. The SFAR includes a POC preparation requirement for carry-on baggage transport, and a battery-packaging standard necessary for the safe carriage of extra POC batteries in carry-on baggage. This rulemaking action is necessary to address the traveling needs of people on oxygen therapy.
