Prevention of Acute Mountain Sickness by Intermittent Hypoxia

Acclimatization by mountaineering prior to high altitude sojourns have shown to be effective in prevention of acute mountain sickness (AMS).

The aim of this study is to investigate whether intermittent exposure to normobaric hypoxia during sleep is also effective to prevent AMS.
