Figure 3From: Efficacy of positive end-expiratory pressure titration after the alveolar recruitment manoeuvre in patients with acute respiratory distress syndromeRespiratory values during the first week of treatment. The closed circles indicate the control group and the open circles denote the decremental positive end-expiratory pressure (PEEP) titration group. Values are expressed as the mean ± standard error of the mean (bars). *p < 0.05 between the control and decremental PEEP titration groups; †p < 0.05 compared with day 0 in the control group; ‡p < 0.05 compared with day 0 in the decremental PEEP titration group.Back to article page
