Effects as a function of altitude Atmospheric pressure decreases exponentially with altitude while the O2 fraction remains constant to about 100 km, so pO2 decreases exponentially with altitude as well.
It is about half of its sea-level value at 5,000 m (16,000 ft), the altitude of the Everest Base Camp, and only a third at 8,848 m (29,029 ft), the summit of Mount Everest. When pO2 drops, the body responds with altitude acclimatization. Mountain medicine recognizes three altitude regions that reflect the lowered amount of oxygen in the atmosphere: High altitude = 1,500–3,500 metres (4,900–11,500 ft)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 (HAPE) and high altitude cerebral edema (HACE).
