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.
Very high altitude = 3,500–5,500 metres (11,500–18,000 ft) Extreme altitude = above 5,500 metres (18,000 ft) Travel to each of these altitude regions can lead to medical problems, from the mild symptoms of acute mountain sickness to the potentially fatal high-altitude pulmonary edema and high-altitude cerebral edema .
Failure to acclimatize may result in altitude sickness, including high-altitude pulmonary edema or cerebral edema . [11] [12] Humans have survived for 2 years at 5,950 m (19,520 ft) [475 millibars (14.0 inHg; 6.89 psi) of atmospheric pressure], which appears to be near the limit of the permanently tolerable highest altitude.

Altitude sickness occurs as the body adjusts to the lack of oxygen at high elevations. There are ways to prevent, lessen the symptoms.
High-altitude pulmonary edema (HAPE) is a life-threatening form of non-cardiogenic pulmonary edema that occurs in otherwise healthy people at altitudes typically above 2,500 meters (8,200 ft). [2] HAPE is a severe presentation of altitude sickness. Cases have also been reported between 1,500–2,500 metres or 4,900–8,200 feet in people who ...

This window can be extended to 36 hours for ascent to altitude and 48 hours for prolonged exposure to altitude following diving. [10] An alternative diagnosis should be suspected if severe symptoms begin more than six hours following decompression without an altitude exposure or if any symptom occurs more than 24 hours after surfacing.
