Non-pulsatile Centrifugal Pumps

  • R. M. BolmanIII


Within a few years of the introduction of cardiopulmonary bypass (CPB) as a life support technique, which made possible a surgical attack on cardiac lesions, investigators began exploring varied applications of this technology for circulatory support of desperately ill patients. In 1962, Dennis and his colleagues demonstrated experimentally that left heart bypass resulted in reduction of the oxygen utilization of the myocardium1. Spencer et al. reported in 1965 a series of four patients requiring assisted circulation following cardiac surgery2. CPB was employed to provide circulatory assistance in these patients and, although none survived, the ability of prolonged bypass to improve tissue perfusion and reduce atrial filling pressures was encouraging and proved quite provocative to subsequent investigators.
