High-altitude illnesses include various grades of acute mountain sickness which must be distinguished from high-altitude pulmonary edema ( TableJ ). Mild to moderate acute mountain sickness is usually a self-limiting disease which improves with progressive acclimatization. In subjects who fail to acclimatize, acute mountain sickness or high-altitude pulmonary edema will progress into its most severe form which, if unrecognized or untreated, leads to death ( Ward §t,ai 1995).
