Abbreviations: pHa: arterial pH; PaCO2: arterial CO2 pressure; PaO2: arterial O2 pressure; MABP: mean arterial blood pressure. The values are the means ± SD for eight experiments.
p < 0.001 for significant difference from pre-bypass conditions.
p < 0.05 for significant difference from pre-bypass conditions.
