Abstract
Pulsatile blood flow in a heart-lung machine is accomplished by pumping blood into a bladder at a constant rate, and cyclically emptying the bladder into aortic line of the heart-lung machine either by means of the bladder's own elasticity or by a mechanical compression mechanism which can be programmed to simulate the human heartbeat.
