Abstract
Although in-series counterpulsation by intraaortic balloon pumping has become an accepted clinical modality of cardiac support, disagreement as to the efficacy of the device is widespread. The purpose of this study was to quantify the possible benefits obtained through cardiac support. The investigation utilized a nonlinear mathematical model of the physiologic-assist system. Predictions by the model were compared with animal experiments. The model uses finite difference equations for fluid flow based on the Navier-Stokes equations and incorporates a multielement, lumped representation for the balloon. The moldel was operated with values for heart rate, pripheral resistance, and left ventricular systolic pressure obtained from the experimental animals.
