Abstract：Objective To examine the effect of positive end-expiratory pressure (PEEP) on the measurement of intra-abdominal pressure (IAP). Method Prospective cohort study was taken. Fifteen mechanically ventilated patients were studied from August 2010 to August 2013 in the intensive care unit. All patients were studied with sequentially increasing PEEP (5 cm H2O and 10 cmH2O) during a PEEP-trial. The IAP measurements obtained at different PEEP values were compared using a paired t-test and Bland-Altman statistics. Results There’s no statistically significant difference between IAP5[(15.56±2.46)mmHg] and IAP10[(15.68±2.36)mmHg](P=0.18). Conclusions In the supine position, when the PEEP value was less than 10 cmH2O, PEEP changes did not obviously effect on IAP measurement.
