Changes in the principal variables during the protocol. T0: Baseline . T1: 60, T2: 120, T3: 180 and T4: 240 minutes after protocol defined ventilation was started. Data are presented as mean (SD). VT: tidal volume, Pplat: plateau pressure, RR: respiratory rate, PaCO2: arterial partial pressure of CO2, pH: acid-base state. *When significant difference (P <0.05) between Pplat-group versus SI-group.
