Abstract :
A model of a rotary ventricular assist device was developed to predict the blood flow through the device using the pressure difference across the device itself. The model contains two parts: inflow and outflow. The structure and parameters of this model were identified by linear regression analysis of data acquired from animal experiments. The model performed well, with a median RMS error of 18.09% for the inflow part and a median RMS error of 16.52% for the outflow portion. This model will be integrated with a cardiovascular model in computer simulation as a platform for developing the physiological controller of the device.
