Blood gas parameters at different timepoints during ventilation. Blood gas parameters were measured at baseline, T0, T1, T3, T5, and T7. Data are presented as the means ± standard deviation (SD). *P < 0.05 vs. baseline; #P < 0.05 vs. control; †P < 0.05 vs. 10 cmH2O. n = 5. P/F: the ratio of arterial oxygen partial pressure and fraction of inspired oxygen; PaCO2: arterial partial carbon-dioxide pressure; HCO3−: bicarbonate; DP: driving pressure
