  1. Ten animals were included in each group. Values are expressed as means ± standard error of the mean. *Statistically significant difference for the comparison of the LVT-30 group with HVT-30 and HVT+DA-30 groups, and of the LVT-60 group with HVT-60 and HVT+DA-60 groups (P = 0.001) at the beginning and end of the experiment. +Statistically significant difference between HVT-30 and HVT+DA-30 groups (P = 0.012) at the end of the experiment. Statistically significant difference between LVT-60 and HVT+DA-60 groups (P = 0.018) at the end of the experiment. Statistically significant difference between LVT-30 and LVT-60 groups (P = 0.025) at the end of experiment. AWP, airway pressure; BP, blood pressure; HVT-30, high tidal volume for 30 minutes; HVT-60, high tidal volume for 60 minutes; HVT+dopamine-30, high tidal volume plus dopamine for 30 minutes; HVT+dopamine-60, high tidal volume plus dopamine for 60 minutes; LVT-30, low tidal volume for 30 minutes; LVT-60, low tidal volume for 60 minutes.
