Q: In abdominal compartment syndrome (ACS), intra-abdominal pressure (IAP) should be measure at? (select one)

A) End-Inspiration

B) End- expiration
C) continuous respiration
D) Mean of end-inspiration and end-expiration values


Answer: B

IAP is usually measured indirectly by using intra-vesicular pressure as measured through a bladder catheter.

IAP should be measured in millimeters of mercury at end-expiration; the patient should be supine and refrain from spontaneous muscle contractions. The midaxillary line is used as the zero reference level for IAP measurement.
