摘要： A CPU 9 controls an air supplying/discharging device to set a pressure of air within a-cuff to 60 mmHg for 60 seconds before making a blood pressure measurement, detects pulse waves of the cuff pressure for such period of time, and calculates a degree of stability of the detected pulse waves. When a blood pressure measurement is made, the CPU reduces the cuff pressure by a step pressure reducing operation whose step duration corresponds to the calculated degree of stability.
