Intraabdominal hypertension is defined as elevated pressure without overt organ failure (table below). Among critically ill patients, intraabdominal hypertension is much more common than abdominal compartment syndrome. Although moderate intraabdominal hypertension doesn't cause obvious multiorgan failure, it may cause organ injury particularly to the kidneys. #Diagnosis #Intraabdominal #Hypertension #IAH #Grades #Classification #ACS #Compartment #Syndrome
