Claim 0:
1. A method of operating a blood pump system, the method comprising:
energizing an implanted blood flow sensor at a first time for a first period;
measuring with the implanted blood flow sensor a flow rate of blood-pumped during the first period;
deenergizing the implanted blood flow sensor at the end of the first period;
determining an amount of power consumed by a blood pump motor during the first period;
determining a blood pump motor speed during the first period;
deriving a flow rate of blood through the blood pump during the first period as a function of the power consumed, and blood pump motor speed; and
delaying measuring a flow rate at a second time based on the magnitude of a difference between the measured blood flow rate during the first period and the derived blood flow rate during the first period.
