2. High altitude breathing apparatus - Wikipedia

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

   High altitude breathing apparatus is used for unpressurised (ambient pressure) aeronautical and mountaineering activities where the oxygen content of the natural atmosphere is insufficient for maintaining physical activity, consciousness, or life, but the atmospheric pressure is sufficient that a pressure suit is not needed.

3. Effects of high altitude on humans - Wikipedia

   en.wikipedia.org/wiki/Effects_of_high_altitude...

   Mitigation may be by supplementary oxygen, pressurisation of the habitat or environmental protection suit, or a combination of both. In all cases the critical effect is the raising of oxygen partial pressure in the breathing gas. [1] Room air at altitude can be enriched with oxygen without introducing an unacceptable fire hazard.

4. Death zone - Wikipedia

   en.wikipedia.org/wiki/Death_zone

   Bottled oxygen can help mountaineers survive in the death zone. Mountaineers use supplemental oxygen in the death zone to reduce deleterious effects. An open-circuit oxygen apparatus was first tested on the 1922 and 1924 British Mount Everest expeditions; the bottled oxygen taken in 1921 was not used (see George Finch and Noel Odell).

5. Altitude sickness - Wikipedia

   en.wikipedia.org/wiki/Altitude_sickness

   Oxygen from gas bottles or liquid containers can be applied directly via a nasal cannula or mask. Oxygen concentrators based upon pressure swing adsorption (PSA), VSA, or vacuum-pressure swing adsorption (VPSA) can be used to generate the oxygen if electricity is available. Stationary oxygen concentrators typically use PSA technology, which has ...

6. High-altitude pulmonary edema - Wikipedia

   [3] [9] [15] Giving oxygen at flow rates high enough to maintain an SpO 2 at or above 90% is a fair substitute for descent. [3] [9] [15] In the hospital setting, oxygen is generally given by nasal cannula or face mask for several hours until the person is able to maintain oxygen saturations above 90% while breathing the surrounding air.
