The values are mean ± SD for 9 participants. PaCO2 and PaO2 indicate arterial carbon dioxide and oxygen pressures, respectively; SaO2, arterial oxygen saturation; PfvO2, femoral venous oxygen pressure. Arterial and venous samples were obtained under normoxic conditions at SL and during exposure to HA (4559 m) for 7 to 9 days. The calculation of statistical differences from normoxia was performed using the Wilcoxon test.
