An apparatus for driving a blood pump such as an artificial pump. The apparatus comprises a pressure pulse generator for producing pressure pulses, a pressure detector for detecting the pressure produced by the pressure pulse generator, and an electrical control unit (ECU) consisting of a microcomputer. The ECU estimates the pressure range obtained after the pressure is switched from a positive value to a negative value or vice versa, from the pressure obtained before the pressure is switched. The ECU then compares the pressure obtained after the switch of the pressure with the pressure range to determine whether the pressure is abnormal or not.
