Boxplots for transpulmonary and respiratory system driving pressures by intraabdominal pressure level at “standard PEEP” and “targeted PEEP.” (A) Transpulmonary driving pressure, (B) respiratory system driving pressure. Green boxes represent the standard PEEP group, orange boxes, the targeted PEEP group. P values reported are from the multivariable analysis. Transpulmonary and respiratory system driving pressures are reported in cm H2O and intraabdominal pressure in mmHg. PEEP, positive end–expiratory pressure.
