Bottled oxygen, more broadly known as high pressure compressed oxygen, medical oxygen, and aviator's oxygen, is oxygen in small, portable, high-pressure storage cylinders. For aviation, the weight of the cylinder is usually not critical, and the choice of material may be affected by economic considerations such as purchase price and useful ...
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.
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).
On Thursday (June 10) morning, a team of over a dozen health workers carrying medical kits and equipment, including oxygen cylinders, reached Lidderwat.In a meadow surrounded by mountain peaks ...
Altitude sickness, the mildest form being acute mountain sickness (AMS), is a harmful effect of high altitude, caused by rapid exposure to low amounts of oxygen at high elevation. [ 1 ] [ 2 ] [ 3 ] People's bodies can respond to high altitude in different ways.
Among the different native highlander populations, the underlying physiological responses to adaptation differ. For example, among four quantitative features, such as resting ventilation, hypoxic ventilatory response, oxygen saturation, and hemoglobin concentration, the levels of variations are significantly different between the Tibetans and the Aymaras.

The fabled expedition of Ernest Shackleton, the Anglo-Irish explorer who led 27 men on a voyage to Antarctica in 1914 aboard the three-masted barquentine schooner Endurance, only to see his ship ...
Mountain sickness may progress to HACE (high-altitude cerebral edema) and HAPE (high-altitude pulmonary edema), both of which can be fatal within 24 hours. [42] [44] [46] In high mountains, atmospheric pressure is lower and this means that less oxygen is available to breathe. [42] This is the underlying cause of altitude sickness.
