Oxygen saturation (SpO2) in %, heart rate (HR) in beats per min, systolic (Sys. Bp) and diastolic (Dia. Bp) blood pressure in mmHg of baseline measurements and during hypoxia.

BLPHE and BLAHE: Baseline measurements of the passive hypoxic exposure (PHE) and the active hypoxic exposure (AHE) of the whole group, HypoxiaPHE and HypoxiaAHE: measurements during PHE and AHE (average of H2–H8) of the whole group. AMS+ and AMS−: subject with and without AMS. pa: difference between BLPHE and HypoxiaPHE respectively BLAHE and HypoxiaAHE, pb: difference between AMS− and AMS+ subjects during PHE respectively AHE. Values are expressed as means ± standard deviation.
