- Ten animals were included in each group. Values are expressed as means ± standard error of the mean. *Statistically significant differences between high tidal volume for 30 minutes (HVT-30) and HVT for 60 minutes (HVT-60) groups (P = 0.014), and between HVT plus dopamine for 30 minutes (HVT-dopamine-30) and HVT plus dopamine for 60 minutes (HVT+DA-60) groups (P = 0.05). †Statistically significant difference between HVT-30 and HVT-30+DA groups (P = 0.023). PCO2, partial carbon dioxide tension; PO2, partial oxygen tension; SO2, oxygen saturation.
