study of hepatopulmonary syndrome among cirrhotic patients using different cut off values for Hypoxaemia

ABSTRACT

Introduction: Hepatopulmonary syndrome [HPS] is characterized by the clinical triad of liver disease, arterial deoxygenation, and widespread pulmonary vascular dilatation. Various threshold values defining arterial hypoxaemia have been recommended and used in previous publications PaO2 <70 mm Hg, PaO2 <80 mm Hg, AaDO2 >15 mm Hg, and AaDO2 >20 mm Hg. These different threshold values may result in a different prevalence of HPS
