Take the Oxygen Concentrator Survey


A few revolutionary machines have been released over the past few years, and some older models have been updated with the new expectations that come along with the release of new oxygen technologies. The most recent technological advancements have brought the developments of some portable machines that are bringing a whole new concept of freedom to oxygen users. Of course, not every oxygen therapy product will be right for you. You’ll need to make sure the POC can meet all of your needs.

Portable Concentrator Frequently Asked Questions
Will a POC meet your daily oxygen needs?
Your mobile concentrator needs to be able to provide you with the oxygen dosage you need at all times, no matter where you are or what you're doing. Your oxygen needs will be different when you're physically active when you're sleeping and or sitting and watching television. The POC needs to be able to detect the changes in your breath rate and compensate accordingly.
Is a portable oxygen concentrator truly portable?
By definition, a portable unit needs to be light enough so that you don't feel burdened while carrying it around anywhere you need to go. You have to take into consideration the weight of the unit, including the weight of the battery and accessories you will be carrying around along with it. You might also need to bring along extra batteries and power supplies. You should always expect to add a few extra pounds for the additional batteries if you are out and about all day.
Can you fly with a portable concentrator?
Yes. The Federal Aviation Administration or FAA, requires airlines based in the United States and foreign airlines flying into the U. S. permit passengers to operate portable oxygen concentrators approved by FAA during all phases of a flight if the unit displays a manufacturer’s sticker. The sticker indicates it meets FAA requirements for portable medical devices. The FAA has approved over 20 oxygen concentrators for air travel on all U.S. aircraft with more than 19 seats, and every portable unit we offer is approved for flights.
Do I need a prescription to buy a portable oxygen concentrator?
Yes. Because the FDA classifies medical grade oxygen as a drug, and by Federal law, a prescription is required to purchase oxygen-related medical devices, such as portable oxy concentrators. Your doctor or health care provider can assist in obtaining a prescription.
