Altitude acclimatization is the process of adjusting to decreasing oxygen levels at higher elevations, in order to avoid altitude sickness. [17] Once above approximately 3,000 metres (10,000 ft) – a pressure of 70 kilopascals (0.69 atm) – most climbers and high-altitude trekkers take the "climb-high, sleep-low" approach.
Peter H. Hackett is an American mountaineer and medical doctor. He is the third person to have summited Mount Everest in a solo ascent, climbing from South Col to the top on October 24, 1981. He studies the effect of altitude on human physiology, and is the founder of a medical rescue camp on Everest and a rescue clinic and lab on Mount Denali ...
This approach was inspired by the work of associate professor of Emergency Medicine at the Harvard Medical School N. Stuart Harris, who has been studying the effects of altitude sickness on mountain climbers, such as those who climb Mount Everest. Harris noticed that the consequences of high level altitude sickness on the human body mirrored ...
Altitude sickness occurs as the body adjusts to the lack of oxygen at high elevations. There are ways to prevent, lessen the symptoms.
First aid at altitude is oxygen at the highest practicable concentration and earliest and largest practicable reduction in cabin altitude. Ground-level 100% oxygen therapy is suggested for 2 hours following type-1 decompression sickness that occurs at altitude, if it resolves upon descent.
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 .
Tracee Lee Metcalfe is a high-altitude alpinist, backcountry skier and internal medicine physician from Vail, Colorado. Metcalfe received her M.D. from University of Colorado Denver's School of Medicine. [1] [2] She first started climbing eight-thousanders in 2015. [3]
Doctors on the ground can give advice. Here's how they work. If there's a medical emergency on your flight, the cabin crew is likely not flying solo. Doctors on the ground can give advice.
