Portable oxygen concentrator used with bottle humidifier POCs operate on the same principle as a home concentrator, pressure swing adsorption . [ 6 ] The basic set up of a POC is a miniaturized air compressor , a cylinder filled containing the sieve, a pressure equalizing reservoir and valves and tubes.
An oxygen concentrator is a device that concentrates the oxygen from a gas supply (typically ambient air) by selectively removing nitrogen to supply an oxygen-enriched product gas stream. They are used industrially, to provide supplemental oxygen at high altitudes, and as medical devices for oxygen therapy .
Medical oxygen storage tanks at the Royal Women's Hospital, Melbourne, Australia. Oxygen may be used for patients requiring supplemental oxygen via mask. Usually accomplished by a large storage system of liquid oxygen at the hospital which is evaporated into a concentrated oxygen supply, pressures are usually around 345–380 kPa (50.0–55.1 psi), [1] [2] or in the UK and Europe, 4–5 bar ...
Ventec developed the VOCSN unified respiratory system, which is a portable personal medical device that includes a ventilator, 6 L/min portable oxygen concentrator, cough assist, suction, and nebulization therapies for the patient. [7] The name of the device is an acronym derived from the names of these five functions. [8]
Pulling down on one oxygen mask starts the oxygen supply for that mask only. The entire system can usually be reset in the cockpit or in some other location in the aircraft. [citation needed] A decentralized gaseous system, often called a pulse oxygen system, [4] is used on some modern airliners such as the Boeing 787. These systems have a ...

Test bench for a miner's closed circuit self-rescuers. A self-contained self-rescue device, SCSR, self-contained self-rescuer, or air pack is a type of closed-circuit SCBA [1] with a portable oxygen source for providing breathable air when the surrounding atmosphere lacks oxygen or is contaminated with toxic gases, e.g. carbon monoxide.
