a) DP, driving pressure; b) Cdyn, respiratory system compliance; c) Pplat, plateau pressure; d) VTalv/VDalv, alveolar dead space to alveolar tidal volume. Values are shown as median and standard deviation. preRM and postRM represent values before and after the recruitment maneuver was performed. OLA represent values of the patients randomized to open-lung approach (OLA) and RM-5 represent values of the patients randomized to a post-RM PEEP of 5 cmH2O. * when P<0.05 and ** P<0.001.
