ABSTRACT:
A blood pressure measuring apparatus comprises an inflatable cuff which is adapted to be wound around a body portion of a living subject, an air pump which supplies a pressurized air to the cuff to inflate the cuff and thereby increase an air pressure in the cuff, to press a body portion of the subject, a pump-output-power control device which controls an output power of the air pump to increase an air pressure in the pump to a predetermined target pressure value, a pressure sensor that detects the pressure of the cuff, first-pump-output setting means for setting a predetermined first pump output power, a timer which measures a basic time period needed to increase the pressure in the cuff, second-pump-output power determining means for determining a second pump output power corresponding to a predetermined pressure-increase rate of the cuff, a cuff pressure decreasing device that decreases the pressure of the cuff, and a measuring device which measures at least one blood pressure value of the living subject while the pressure of the cuff is decreased from a target pressure value by the cuff pressure decreasing device.
