Figure 1From: Positive end-expiratory pressure affects the value of intra-abdominal pressure in acute lung injury/acute respiratory distress syndrome patients: a pilot studyEffects of PEEP on IAP measure in all patients ( n = 30), low IAP group ( n = 15) and high IAP group ( n = 15). *P < 0.05 PEEP0 vs PEEP12. **P < 0.01 PEEP0 vs PEEP12. IAP, intra-abdominal pressure; PEEP, positive end-expiratory pressure.Back to article page
