From: Commonly applied positive end-expiratory pressures do not prevent functional residual capacity decline in the setting of intra-abdominal hypertension: a pig model

Figure 1

Influence of intra-abdominal pressure and positive end-expiratory pressure on functional residual capacity. Functional residual capacity (FRC) in litres (L) in function of different levels of intra-abdominal pressures (IAP) (3 mmHg (baseline), 18 mmHg (grade II intra-abdominal hypertension), and 26 mmHg (grade IV intra-abdominal hypertension)) at different levels of positive end-expiratory pressures (PEEP). Mean and SE are shown. ANOVA and post hoc Student-Newman-Keuls were used for statistical testing. *, P < 0.05 within an IAP setting vs. the corresponding value at 5 cmH2O PEEP. For clarification additional symbol is added where necessary. At each PEEP setting, all FRC values were significantly different compared to the corresponding value at baseline IAP (P < 0.05).
