Figure 3

Effect of PEEP on the (a) static elastance of the respiratory system (Estat, rs), (b) static elastance of the chest wall (Estat, CW), (c) static elastance of the lung components (Estat, L) and (d) the volume exhaled from PEEP to ZEEP in patients with normal IAP (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. Data are presented as mean ± standard deviation. ZEEP = zero end-expiratory pressure.
