Haemodynamic changes after the withdrawal of mechanical ventilation. Systolic blood pressure (a), mean arterial pressure (b) and pulse pressure (c) for each group are shown. The rats in the Air group were ventilated with room air while the other groups were ventilated with 100% oxygen. The NS group were infused with 6 mL normal saline and the HbV group was infused with 6 mL HbV. The arrows indicate periods of fluid infusion. The differences between the groups were analysed by a one-way repeated measure ANOVA followed by a Holm-Sidak test. SBP, systolic blood pressure; MAP, mean arterial pressure; PP, pulse pressure. Symbols represent significant differences. *: P < 0.05; ** P < 0.01; *** P < 0.001
