NCT ID: NCT01465971 Completed - Clinical trials for Cheyne-Stokes Respiration

Monitoring of the Cerebral Tissue Oxygenation and Perfusion in the Adapting Climber During Sleep in High Altitude

PerOxySleep
Start date: May 2011
Phase: N/A
Study type: Observational

One of the major challenges in adapting to high altitudes is that with increasing altitude sleeping quality declines rapidly. Thus, the night sleep can only provide limited to none regeneration. It usually takes a prolonged stay at a constant altitude to adapt sufficiently to the altitude and to have a refreshing night sleep. 1975 Reit et. al showed in their EEG-recordings that the sleep architecture (the regular succession of the particular sleep phases) is disturbed by repeating arousals which occur due to an irregularity in the breathing rhythm. The purpose of this study is to create a better understanding of the underlying mechanisms that lead to failed acclimatization and AMS, due to sleep disturbance.

NCT ID: NCT00498563 Completed - Hypoxia Clinical Trials

Effects of Mild Hypobaric Hypoxia on Sleep and Post-sleep Performance

Start date: October 2006
Phase: N/A
Study type: Interventional

Hypobaric hypoxia (decreased oxygen supply to body tissues due to low atmospheric pressure) caused by exposure to high altitude disrupts sleep. Sleep deprivation is associated with degraded post-sleep performance of neurobehavioral tasks. The lowest altitude at which sleep and/or post-sleep performance are affected is not known. The study hypothesis is that sleep and/or post-sleep performance of neurobehavioral tasks will occur due to hypobaric hypoxia at altitudes of 8,000 or less.
