RECRUITINGNocturnal oxygen saturation (SpO2)
MCP-related difference in altitude-induced change in the mean nocturnal oxygen saturation measured by pulse oximetry.
Time frame: Night 1 at 760 m and Night 1 at 3600 m
Nocturnal oxygen desaturation index (ODI)
MCP-related difference in altitude-induced change in the ODI (number of ∆SpO2 \>3% per hour time in bed measured by pulse oximetry).
Time frame: Night 1 at 760 m and Night 1 at 3600 m
