Data are mean ± SE in the Sham (n = 5), Vag (n = 5), HS (n = 7) and Vag + HS (n = 7) groups. * P < 0.01 vs. the Sham group; ^#p < 0.05 vs. the Vag group. pH -1, PvCO₂–1, PvO₂–1, HCO₃–1 and base excess (BE-1) are the venous blood parameters at baseline. pH -2, PvCO₂–2, PvO₂–2, And HCO₃⁻-2 and BE-2 are the venous blood parameters at the end of the experiments. PvO₂: venous oxygen pressure, PvCO₂: venous carbon dioxide pressure. Barometric pressure: 630 mmHg
