From: Matching positive end-expiratory pressure to intra-abdominal pressure improves oxygenation in a porcine sick lung model of intra-abdominal hypertension

Figure 2

Static elastance of the total respiratory system (E RS ) as a composite of chest wall (E CW , black filled bar) and lung elastance (E L , white or grey filled bar) in function of different levels of intra-abdominal hypertension (IAH) (baseline (3 cmH 2 O), grade II IAH, (25 cmH 2 O = 18 mmHg), and grade III IAH (30 cmH 2 O = 22 mmHg)) at different degrees of IAP-matching levels of positive end-expiratory pressures (PEEP). OA, oleic acid. Mean and SE (ERS) are shown. ANOVA and post hoc Student-Newman-Keuls were used for statistical testing. §, P <0.05 comparing ERS before and after oleic acid. *, P <0.05 ERS within an IAP setting versus the corresponding value at 5 cmH2O PEEP. There were no significant differences in ERS within an IAP setting comparing moderate versus high PEEP. #, P <0.05 ERS within a PEEP setting versus the corresponding value at baseline IAP. ANOVA, analysis of variance.
