Effect of Arteriovenous Fistula on Mean Arterial Blood Pressure, Coronary Blood Flow, Cardiac Output, Oxygen Consumption, Work and Efficiency

Abstract

In the anesthetized dog, acute arteriovenous fistulae sufficient to increase the cardiac output by from 16 to 130% resulted in an increase in the coronary blood flow even in the presence of a definite and even marked drop in the mean arterial blood pressure. The arteriovenous fistulae also resulted in an increase of the cardiac work and oxygen consumption as well as the cardiac efficiency.
