Figure 5

Effect of PEEP on (a) cardiac index (CI), (b) mean arterial pressure (MAP), (c) intrathoracic blood volume index (ITBI), and (d) extravascular lung water index in patients with normal normal intra-abdominal pressure (shaded bars) and intra-abdominal hypertension (dotted bars). Asterisk: P < 0.05 vs positive end-expiratory pressure (PEEP) 5; Single Triangle: P < 0.05 PEEP 10 vs PEEP 15; Double Triangle: P < 0.05 PEEP 10 vs PEEP 20; Triple Triangle: P < 0.05 PEEP 15 vs PEEP 20; Hash key: P < 0.05 between groups. Data are presented as mean ± standard deviation.
