  2. Portable oxygen concentrator - Wikipedia

    en.wikipedia.org/wiki/Portable_oxygen_concentrator

    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.

  3. Oxygen tank - Wikipedia

    en.wikipedia.org/wiki/Oxygen_tank

    Oxygen tanks are used to store gas for: medical breathing (oxygen therapy) at medical facilities and at home (high pressure cylinder) breathing at altitude in aviation, either in a decompression emergency, or constantly (as in unpressurized aircraft), usually in high pressure cylinders; oxygen first aid sets, in small portable high pressure ...

  4. Oxygen concentrator - Wikipedia

    en.wikipedia.org/wiki/Oxygen_concentrator

    As the first cylinder reaches near pure oxygen (there are small amounts of argon, CO 2, water vapour, radon, and other minor atmospheric components) in the first half-cycle, a valve opens and the oxygen-enriched gas flows to the pressure-equalizing reservoir, which connects to the patient's oxygen hose. At the end of the first half of the cycle ...

  5. Medical gas supply - Wikipedia

    en.wikipedia.org/wiki/Medical_gas_supply

    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 ...

  6. High altitude breathing apparatus - Wikipedia

    en.wikipedia.org/wiki/High_altitude_breathing...

    Bottled oxygen, more broadly known as high pressure compressed oxygen, medical oxygen, and aviator's oxygen, is oxygen in small, portable, high-pressure storage cylinders. For aviation, the weight of the cylinder is usually not critical, and the choice of material may be affected by economic considerations such as purchase price and useful ...

  7. Self-contained breathing apparatus - Wikipedia

    en.wikipedia.org/wiki/Self-contained_breathing...

    The endurance of the cylinder can be calculated from the volume, pressure and breathing rate of the user. The formula: volume (in liters) × pressure (in bars) / 40 (litres per minute) - 10 minutes (the 10 minutes is a safety margin, or reserve), so a 6-liter cylinder, of 300 bar, is 6 × 300 / 40 - 10 = 35 minutes working duration.
