    It often comes as a 50/50 mixture with oxygen. [1] Devices with a demand valve are available for self-administration. [5] The setup and maintenance is relatively inexpensive for developing countries. [6] [7] There are few side effects, other than vomiting, with short-term use. [1] [2] With long-term use anemia or numbness may occur. [2]

  3. Diving cylinder - Wikipedia

    en.wikipedia.org/wiki/Diving_cylinder

    The term "oxygen tank" is commonly used by non-divers; however, this is a misnomer since these cylinders typically contain (compressed atmospheric) breathing air, or an oxygen-enriched air mix. They rarely contain pure oxygen, except when used for rebreather diving, shallow decompression stops in technical diving or for in-water oxygen ...

  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 ...

    en.wikipedia.org/wiki/Oxy-fuel_welding_and_cutting

    Fuel and oxygen tanks should be fastened securely and upright to a wall, post, or portable cart. An oxygen tank is especially dangerous because the gas is stored at a pressure of 21 MPa (3,000 psi; 210 atm)) when full. If the tank falls over and damages the valve, the tank can be jettisoned by the compressed oxygen escaping the cylinder at high ...

  9. Gas blending for scuba diving - Wikipedia

    en.wikipedia.org/wiki/Gas_blending_for_scuba_diving

    The compressor and particularly the compressor oil, must be suitable for this service. If the oxygen fraction is less than 40%, some countries do not require the cylinder and valve to be cleaned for oxygen service. Mixing by mass fraction: oxygen is added to a partially full cylinder that is accurately weighed until the required mix is achieved.
