Compliance in non-gravity-dependent (a) and gravity-dependent (b) lung regions. Compliance in different regions was calculated by dividing ∆ZROI by tracheal pressure changes assuming no flow at the end of inspiration and expiration. Compliance = ∆ZROI/driving pressure. ap < 0.05, comparison between before and after recruitment maneuver. SI, sustained inflation; IP, increments of PEEP; PCV, pressure-controlled ventilation; RM, recruitment maneuvers; ROI, regions of interest; ∆ ZROI, the regional impedance change for a ROI
