Abstract
Rotary blood pumps are widely used as ventricular assist devices (VAD) for patients suffering from heart disease. For monitoring and controlling the VAD, flow rate information is required. However, flow sensors tend to cause some problems. We studied a method to estimate the outflow of a blood pump with rotational speed and supplied electrical power. We implanted two pumps as a biventricular VAD in a calf, then measured flow rate and rotational speed every 2 days. The accuracy of the estimation method was evaluated with data obtained from a long term experiment.
