Time course of cardiac output (linear mixed effects model: time, P < 0.001; positive end-expiratory pressure [PEEP], P = 0.684; PEEP:time interaction, P = 0.315; A), mean arterial pressure (linear mixed effects model: time, P < 0.001; PEEP, P = 0.543; PEEP:time interaction, P = 0.011; B), cumulative resuscitation fluids (linear mixed effects model: time, P < 0.001; PEEP, P < 0.001; PEEP:time interaction, P < 0.001; C), and noradrenaline (linear mixed effects model: time, P < 0.001; PEEP P = 0.001; PEEP:time interaction, P = 0.003; D) in the different PEEP groups.
