While there are no accurate synonyms, the term intra-abdominal hypertension (IAH) is often used to describe one of the two required key elements for the syndrome to occur – Intra-Abdominal Hypertension (IAH). IAH is defined as an intra-abdominal pressure (IAP) that persistently equals or exceeds 12 mmHg (see Intra-Abdominal Pressure Monitoring) [1]


The World Society of Abdominal Compartment Syndrome (www.WSACS.org) has derived a consensus statement with definitions of IAH and ACS [1]. The ACS is defined as an intra-abdominal pressure that exceeds 20 mmHg and is accompanied by an attributable organ failure. This definition acknowledges that the syndrome may occur with or without an abdominal perfusion pressure (APP) <60 mmHg. The APP can be calculated by subtracting the IAP from the mean arterial pressure (MAP), APP = MAP – IAP. The formula for APP is similar to the one used to assess intracranial pressure (ICP) and cerebral perfusion pressure (CPP = MAP – ICP) and...
