Should not yet inform clinical device use; extends preclinical data on pump flow control but leaves human translation open.
A novel bypass flow rate estimation and control system for an implantable centrifugal blood pump demonstrated moderate reactivity and accuracy in preclinical testing.
Wakisaka et al. (1998) studied Circulatory assist. Bypass flow rate estimation and control system (BECS) was evaluated on Reactivity and accuracy of the BECS (measured flow rate maintenance). A bypass flow rate estimation and control system for an implantable centrifugal blood pump demonstrated moderate reactivity and accuracy, maintaining a measured flow rate of 5.0 +/- 0.2 L/min in vivo.
