Figure 1From: Adjusting tidal volume to stress index in an open lung condition optimizes ventilation and prevents overdistension in an experimental model of lung injury and reduced chest wall compliance 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.Back to article page
