Brief Summary

This study analyses both Protein Expression and emotional alterations during hypobaric hypoxia in volunteers of different groups.

Detailed Description

This study analyses both Protein Expression and emotional alterations during hypobaric hypoxia in volunteers of different groups.

15 different Groups are analysed: control Group, 5000ft Group, 8000 ft Group, 10000ft Group and 15000ft Group - all for 15, 30, and 60 minutes.

Primary Outcome Measures
NameTimeMethod
Protein Expression before hypoxiaMeasurement immediately 1 minute before of hypoxia/experiment

proteomic profiling of Serum by 2D-gels. All Proteins present in the sample will be identified by proteomics

Emotional assessment tearsMeasurement starts immediately with hypoxia in the pressure chamber. duration 10 minutes

Emotional tears test

Emotional assessmentMeasurement in the pressure chamber after tears test (i.e. 10 minutes after start). duration 10 minutes

Protein Expression after hypoxiaMeasurement immediately and at termination (i.e., 1 minute after) of hypoxia/experiment

proteomic profiling of Serum by 2D-gels. All Proteins present in the sample will be identified by proteomics

Emotional assessment moodMeasurement in the pressure chamber after stroop test (i.e. 20 minutes after start). duration 10 minutes
