Abstract

We evaluated hemody-namics of a centrifugal pump by means of short circuit in vitro and in vivo experiments using adult dogs. The Sarns model 7800 was used as the centrifugal pump. In the experiment of short circuit, the line pressure was curvilinearly correlated with the revolution with statistical significance. The flow was linearly correlated with the revolution with statistical significance. In the experiment of adult dogs the flow was linearly correlated with the revolution with coefficiency of 0.675. In range from 1500 up to 2250rpm, the flow pporoximately corresponded to the revolution, which means almost stable extracorporeal circulation could be obtained in its usual range.
