A portable oxygen concentrator (POC) is a device used to provide oxygen therapy to people that require greater oxygen concentrations than the levels of ambient air. It is similar to a home oxygen concentrator (OC), but is smaller in size and more mobile. They are small enough to carry and many are now FAA-approved for use on airplanes.

Portable Oxygen Concentrator
A portable oxygen concentrator includes a pair of sieve beds, a compressor for delivering air to the sieve beds, a reservoir receiving oxygen-enriched gas from the sieve beds, and an air manifold attached to the first ends of the sieve beds. A set of valves operate under the control of a controller for selectively opening and closing the valves to alternately charge and purge the sieve beds to deliver oxygen-enriched gas into the reservoir. In addition, an exhaust passage communicates with the plurality of sieve beds to deliver a flow of nitrogen evacuated from the sieve beds such that the flow of the nitrogen is directed at or across the controller to cool the controller.
