In recent years, the use of rotary blood pumps (RBPs) as continuous ow VADs has surged ahead, and virtually eliminated the use of pulsatile-ow or volume-displacement pumps for implantable, chronic mechanical circulatory support (MCS). Circuit Design modications like that in Saispandan has imparted pulsatility into RBP.Impeller designs are a signicant factor when designing centrifugal pumps as mechanical circulatory assist devices as smaller diameter impellers with higher rotational speeds to achieve target outputs would cause more blood component trauma compared to larger diameter impellers.Hydraulic performance and hemolysis tests in the same pump housing with different prototypes is needed. Ventricular assist parameters for efcient circulatory support would include an output of 5 L/min against 100 mmHg at speeds of 2500-3500 rpm. Vein height does not contribute signicantly to evaluation metric in most studies. |
