Abstract

Indirect hemodynamic indices of cardiac oxygen balance during in-series cardiac assistance are evaluated using computer simulation of the canine cardiovascular system. Only indices that reflect benefits to the left ventricle and can be obtained during treatment in the clinical setting are examined. The indices were tested using models of two devices: the intraaortic balloon pump and an in-series blood pump. In both cases the most accurate and sensitive index of cardiac oxygen balance is the difference between aortic mean diastolic pressure and ventricular peak systolic pressure.
