  2. Oxygen tank - Wikipedia

    en.wikipedia.org/wiki/Oxygen_tank

    An oxygen tank is an oxygen storage vessel, which is either held under pressure in gas cylinders, referred to in the industry as high pressure oxygen cylinders, or as liquid oxygen in a cryogenic storage tank.

  3. 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.

  4. 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 ...

  5. Oxygen storage - Wikipedia

    en.wikipedia.org/wiki/Oxygen_storage

    Methods of oxygen storage for subsequent use span many approaches, including high pressures in oxygen tanks, cryogenics, oxygen-rich compounds and reaction mixtures, and chemical compounds that reversibly release oxygen upon heating or pressure change. O 2 is the second most important industrial gas.

  6. Gas cylinder - Wikipedia

    en.wikipedia.org/wiki/Gas_cylinder

    A gas cylinder is used to store gas or liquefied gas at pressures above normal atmospheric pressure. [2] In South Africa, a gas storage cylinder implies a refillable transportable container with a water capacity volume of up to 150 litres. Refillable transportable cylindrical containers from 150 to 3,000 litres water capacity are referred to as ...

  7. Oxygen concentrator - Wikipedia

    en.wikipedia.org/wiki/Oxygen_concentrator

    An oxygen concentrator takes in air and removes nitrogen from it, leaving an oxygen-enriched gas for use by people requiring medical oxygen due to low oxygen levels in their blood. [4] Oxygen concentrators provide an economical source of oxygen in industrial processes, where they are also known as oxygen gas generators or oxygen generation plants.

  8. Rebreather - Wikipedia

    en.wikipedia.org/wiki/Rebreather

    A store of oxygen, usually as compressed gas in a high pressure cylinder, but sometimes as liquid oxygen, that feeds gaseous oxygen into the ambient pressure breathing volume, either continuously, or when the user operates the oxygen addition valve, or via a demand valve in an oxygen rebreather, when the volume of gas in the breathing circuit ...

  9. 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.
