Brief Title

Prevention of Acute Mountain Sickness by Intermittent Hypoxia

Official Title

Prevention of Acute Mountain Sickness by Sleeping at Simulated Altitude (Normobaric Hypoxia)

Brief Summary

      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.
