Lung-Protective Ventilation Strategies for Relief from Ventilator-Associated Lung Injury in Patients Undergoing Craniotomy: A Bicenter Randomized, Parallel, and Controlled Trial

Figure 2

Changes in hemodynamic variables among patients who were administered conventional mechanical ventilation with 12 mL/kg tidal volume (VT) and 0 cm H2O positive end-expiratory pressure (PEEP) (CV group) or protective lung ventilation with 6 mL/kg VT and 10 cm H2O PEEP (PV group) during surgery. Bars indicate the standard deviation. The time points for measurements were T1—just before changing the ventilation strategy following stabilization of hemodynamic parameters after intubation; T2 and T3—1 and 3 h, respectively, after changing the ventilation strategy; T4—end of surgery; and T5—immediately after extubation.
