Two Case Studies of Cardiopulmonary Effects of Intra-abdominal Hypertension.
ABSTRACT Intra-abdominal hypertension falsely elevates the pulmonary artery pressure. Volumetric pulmonary artery catheter monitoring is an optionfor estimating preload in this condition. Treatment of intra-abdominal hypertension begins with medical therapy but once abdominal compartment syndrome develops it requires decompressive laparotomy for definitive management. Pulmonary hypertension reduces cardiac function which may be improved with inotropes that simultaneously reduce pulmonary artery pressure. Oxygenation may be improved with elevated PEEP and FiO(2).
