Prevention of Acute Mountain Sickness by Intermittent Hypoxia - Full Text View

Sponsor:	University of Heidelberg
Information provided by:	University of Heidelberg
ClinicalTrials.gov Identifier:	NCT00559832

Purpose

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.
