May enable sensorless PCPS miniaturization; leaves open in vivo and clinical validation.
A novel estimation equation using motor parameters and fluid viscosity accurately estimates flow rate and pressure head in a centrifugal blood pump in vitro, potentially enabling miniaturization of PCPS systems.
Funakubo et al. (2002) studied Percutaneous cardiopulmonary support (PCPS). Estimation equation using motor revolutions per minute and torque vs. Measured flow rate and pressure head was evaluated on Difference between estimated and measured flow rate and pressure head. A novel pump system using motor revolutions and torque accurately estimated flow rate (98% accuracy) and pressure head (94.2% accuracy) in a centrifugal blood pump in vitro.
