PROBLEM TO BE SOLVED: To provide a control program or the like with which such a phenomenon that dilatation timing of a balloon is shifted from a dicrotic notch is controlled, thereby reduction in the effect of IABP accompanying the phenomenon is suppressed.SOLUTION: A drive device control program for intraaorta balloon pumping makes a computer execute: a procedure of storing first time (T) corresponding to the time from a trigger (89) to a dicrotic notch (91) into a storage means (73) a procedure of detecting the trigger from an electrocardiac waveform or a blood pressure waveform, and controlling normal drive of dilating a balloon (32) when the first time elapses after the detection of the trigger and contracting it thereafter and a procedure of detecting the trigger from the electrocardiac waveform or the blood pressure waveform, and controlling detection drive of dilating the balloon when second time (T) longer than the first elapses after the detection of the trigger and contracting the balloon thereafter.
