An interventional study of Hypoxic Exposure in Acute Mountain Sickness, sponsored by Heidelberg University. Completed at 1 site in Germany. Open to male participants aged 18 Years to 50 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2007-11-16.
Sponsored by Heidelberg University · Not applicable, Interventional, and Prevention
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.
189 studies on the registry are indexed under Altitude Sickness; 44 are open to participants now.
