  2. Liquid oxygen supplement - Wikipedia

    en.wikipedia.org/wiki/Liquid_oxygen_supplement

    Liquid oxygen supplement. Liquid oxygen supplements are products that claim to add extra oxygen to the human body, most often through a chemical process in the digestive system, like the breakdown of hydrogen peroxide or magnesium peroxide. While the FDA describes these products as being inert, and has penalized some producers who made explicit ...

  3. Liquid oxygen - Wikipedia

    en.wikipedia.org/wiki/Liquid_oxygen

    Liquid oxygen has a clear light sky-blue color and is strongly paramagnetic: it can be suspended between the poles of a powerful horseshoe magnet. [2] Liquid oxygen has a density of 1.141 kg/L (1.141 g/ml), 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 ...

  4. Liquid breathing - Wikipedia

    en.wikipedia.org/wiki/Liquid_breathing

    Liquid breathing. Liquid breathing is a form of respiration in which a normally air-breathing organism breathes an oxygen -rich liquid (such as a perfluorocarbon ), rather than breathing air, by selecting a liquid that can hold a large amount of oxygen and is capable of CO 2 gas exchange. [1]

  5. Oxygen toxicity - Wikipedia

    en.wikipedia.org/wiki/Oxygen_toxicity

    Oxygen toxicity is a condition resulting from the harmful effects of breathing molecular oxygen ( O. 2) at increased partial pressures. Severe cases can result in cell damage and death, with effects most often seen in the central nervous system, lungs, and eyes. Historically, the central nervous system condition was called the Paul Bert effect ...

  6. Rebreather - Wikipedia

    en.wikipedia.org/wiki/Rebreather

    A rebreather is a breathing apparatus that absorbs the carbon dioxide of a user's exhaled breath to permit the rebreathing (recycling) of the substantially unused oxygen content, and unused inert content when present, of each breath. Oxygen is added to replenish the amount metabolised by the user. This differs from open-circuit breathing ...

  7. High altitude breathing apparatus - Wikipedia

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

    High altitude breathing apparatus is a breathing apparatus which allows a person to breathe more effectively at an altitude where the partial pressure of oxygen in the ambient atmospheric air is insufficient for the task or to sustain consciousness or human life over the long or short term. High altitude breathing sets may be classified by type ...

  8. Medical gas supply - Wikipedia

    en.wikipedia.org/wiki/Medical_gas_supply

    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 (400–500 kPa; 58–73 psi ...
