A key limitation of mechanical ventilators is that they do not measure the Ptp or pleural pressure. Airway pres- sure alone cannot distinguish poor lung compliance from poor chest-wall compliance. High intra-abdominal pres- sure can severely impair chest wall mechanics.9,10 We used esophageal balloon manometry to estimate Ptp and guide optimal PEEP in a patient suspected of having decreased lung compliance due to intra-abdominal hypertension.
