Abstract

Objective: To clarify the effect of progressively increasing intra-abdominal pressure on esophageal pressure, transpulmonary pressure, and functional residual capacity. Design: Controlled application of increased intra-abdominal pres-sure at two positive end-expiratory pressure levels (1 and 10 cm HjO) in an anesthetized porcine model of controlled ventilation. Setting: Large animal laboratory of a university-affiliated hospital. Subjects: Eleven deeply anesthetized swine (weight 46.2 ±6.2 kg). Interventions: Air-regulated intra-abdominal hypertension (0-25 mmHg). Measurements: Esophageal pressure, tidal compliance, bladder pressure, and end-expiratory lung aeration by gas dilution. Main Resuits: Functional residual capacity was significantly reduced by increasing intra-abdominal pressure at both positive end-expiratory pressure levels (p
