    Liquid oxygen is the liquid form of molecular oxygen. It has a density of 1.141 kilograms per litre (71.2 lb/cu ft), slightly denser than liquid water, and is cryogenic with a freezing point of 54.36 K (−218.79 °C; −361.82 °F) and a boiling point of 90.19 K (−182.96 °C; −297.33 °F) at 1 bar (15 psi).

    en.wikipedia.org/wiki/Oxygen_concentrator

    Oxygen concentrators are used widely for oxygen provision in healthcare applications, especially where liquid or pressurized oxygen is too dangerous or inconvenient, such as in homes or portable clinics, and can also provide an economical source of oxygen in industrial processes, where they are also known as oxygen gas generators or oxygen ...

  4. Liquid breathing - Wikipedia

    en.wikipedia.org/wiki/Liquid_breathing

    Liquid breathing is a form of respiration in which a normally air-breathing organism breathes an oxygen-rich liquid which is capable of CO 2 gas exchange (such as a perfluorocarbon). [ 1 ] The liquid involved requires certain physical properties, such as respiratory gas solubility, density, viscosity, vapor pressure and lipid solubility, which ...

    en.wikipedia.org/wiki/Vacuum_insulated_evaporator

    A vacuum insulated evaporator (VIE) is a form of pressure vessel that allows the bulk storage of cryogenic liquids including oxygen, nitrogen and argon for industrial processes and medical applications. [1] The purpose of the vacuum insulation is to prevent heat transfer between the inner shell, which holds the liquid, and surrounding ...

    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.

  9. Oxygen storage - Wikipedia

    en.wikipedia.org/wiki/Oxygen_storage

    Most humans can function at rest with an oxygen level of 15% at one atmosphere pressure; [1] a fuel such as methane is combustable down to 12% oxygen in nitrogen. A small room of 10 meter 3 has 2.08 meter 3 (2080 liters) or 2.99 kg of oxygen which would occupy 2.62 liters if it was liquid. [2]
