2. Oxygen tent - Wikipedia

   en.wikipedia.org/wiki/Oxygen_tent

   An infant placed under an oxygen tent. An oxygen tent consists of a canopy placed over the head and shoulders, or over the entire body of a patient to provide oxygen at a higher level than normal.

3. High altitude breathing apparatus - Wikipedia

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

   The equipment must supply breathing gas for all users for at least 15 minutes at a cabin altitude of 8,000 ft at a respiratory minute volume of 30 liters per minute, either by continuous flow or via a demand system, and must not cause a significant increase in oxygen content of the local environment.

4. Oxygen concentrator - Wikipedia

   en.wikipedia.org/wiki/Oxygen_concentrator

   An oxygen concentrator is a device that concentrates the oxygen from a gas supply (typically ambient air) by selectively removing nitrogen to supply an oxygen-enriched product gas stream. They are used industrially, to provide supplemental oxygen at high altitudes, and as medical devices for oxygen therapy. [1]

5. Oxygen tank - Wikipedia

   en.wikipedia.org/wiki/Oxygen_tank

   Medical use liquid oxygen airgas tanks are typically 2.4 MPa (350 psi). [citation needed] All equipment coming into contact with high pressure oxygen must be "oxygen clean" and "oxygen compatible", to reduce the risk of fire. [3] [4] "Oxygen clean" means the removal of any substance that could act as a source of ignition. "Oxygen compatible ...

6. 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 ...

7. Oxygen therapy - Wikipedia

   en.wikipedia.org/wiki/Oxygen_therapy

   For this reason, storage vessels, regulators, piping and any other equipment used with highly concentrated oxygen must be "oxygen-clean" prior to use to ensure the absence of potential fuels. This does not only apply to pure oxygen; any concentration significantly higher than atmospheric (approximately 21%) carries a potential ignition risk.
