1. An apparatus comprising:
a blood pump comprising:
an impeller;
a frame configured to be disposed around the impeller;
a motor configured to drive the impeller to pump blood by rotating the impeller, the entire impeller being configured to undergo axial back-and-forth motion relative to the frame, in response to changes in pressure against which the impeller is pumping;
a sensor configured to detect the axial back-and-forth motion of the impeller, and to generate a sensor signal that is indicative of the detected axial back-and-forth motion of the impeller; and
a computer processor configured to receive the sensor signal and to generate an output in response thereto.
