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 .
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.
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 ...
Today [ edit ] Philips Respironics's products include devices for the diagnosis and treatment of sleep apnea including CPAP and bi-level ( BiPAP ) non-invasive ventilation machines, oxygen concentrators for patients requiring supplemental oxygen , infant apnea monitors for infants at risk of SIDS , asthma treatment solutions and hospital ...
The technological and industrial history of Canada encompasses the country's development in the areas of transportation, communication, energy, materials, public works, public services (health care), domestic/consumer and defense technologies. Most technologies diffused in Canada came from other places; only a small number actually originated ...
On-board oxygen generating systems (OBOGS) bleed compressed air from the engines, enrich the oxygen content by removing nitrogen using an oxygen concentrator, and regulate the supply to cabin pressure and temperature. They are continuously available and producing fresh gas when the engine is running.

Uses compressed oxygen. Uses an oxygen-generating solid. This involves a chemical reaction between potassium superoxide with exhaled water and carbon dioxide. A chlorate candle has to be struck to start the device. To reduce pressure buildup from use, a pressure-relief valve with saliva trap is included.
