  Sea level 4900 m 5600 m
Spo2 (%) 97.9 (±0.6) 83.6 (±5.4)* 77.6 (±7.1)*Ψ
Baseline Sto2 (%) 84.4 (±6.0) 69.3 (±8.2)* 64.2 (±6.1)*
Minimum Sto2 (%) 43.2 (±12.1) 29.8 (±12.6)* 22.4 (±11.0)*
Peak Sto2 (%) 94.1 (±1.4) 83.0 (±5.6)* 76.4 (±6.6)*Ψ
Overshoot Sto2 (%) 9.6 (±6.4) 13.7 (±5.0) 12.2 (±6.1)
Downslope (%/min) 13.6 (±3.3) 13.6 (±3.0) 14.2 (±4.4)
