A portable oxygen concentrators, 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 Home Oxygen 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.
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 a airplane.
