    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 ).

  4. Effects of high altitude on humans - Wikipedia

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

    Room air at altitude can be enriched with oxygen without introducing an unacceptable fire hazard. At an altitude of 8000 m the equivalent altitude in terms of oxygen partial pressure can be reduced to below 4000 m without increasing the fire hazard beyond that of normal sea level atmospheric air.

    If the user does not wear a pressure suit or a counter-pressure garment that restricts the movement of their chest, the high-pressure air can cause damage to the lungs. For modern military aircraft such as the United States' F‑22 and F‑35 , both of which have operational altitudes of 18,000 m (59,000 ft) or more, the pilot wears a "counter ...

  9. High-altitude adaptation in humans - Wikipedia

    en.wikipedia.org/wiki/High-altitude_adaptation...

    Highlanders are thus constantly exposed to a low oxygen environment, yet they live without any debilitating problems. [23] One of the best-documented effects of high altitude on non-adapted women is a progressive reduction in birth weight. By contrast, the women of long-resident, high-altitude populations are known to give birth to heavier ...
