PROBLEM TO BE SOLVED: To provide a method of driving a balloon by an IABP driving device capable of preventing formation of a thrombus on a balloon surface. [Solution] A method of driving a balloon by an IABP driving device that attaches a balloon catheter to which a balloon is connected and expands and contracts the balloon, wherein the balloon is continuously synchronized with a heartbeat having a heart rate of 120 bpm or more, and When performing high-speed continuous driving to drive, if the high-speed continuous driving continues for a predetermined time of 30 seconds or more, after performing a resting operation of maintaining the balloon in a contracted state for a predetermined number of heartbeats, the high-speed continuous driving is performed again Perform continuous drive.
