Mountains cover one-fifth of the earth’s surface; 38 million people live permanently at altitudes ≥2400 m, and 100 million people travel to high-altitude locations each year. Skiers in Aspen, religious pilgrims to Lhasa, trekkers and climbers to Kilimanjaro or Everest, and military personnel deployed to high-altitude locales are all at risk of developing acute mountain sickness (AMS), high-alti...

Altitude-related illness.

There are a number of conditions which can be grouped together as ARI. Many represent potentially fatal pathophysiological states that are rapidly reversible if identified and treated properly. Physiological alterations that result from the hypobaric hypoxia of altitude include cerebral vasodilatation, altered ventilatory patterns, pulmonary vasoconstriction, decreased cardiac output, and alter...

These areas include the role and potential mechanisms of brain swelling ...
