Abstract
An oscillometric automatic blood-pressure measuring apparatus, including an inflatable cuff which is adapted to be wound around a portion of a living subject, so as to detect respective amplitudes of a plurality of heartbeat-synchronous pulses of a cuff pulse wave as an oscillatory component that is produced in the cuff in synchronism with heartbeats of the subject in a cuff-pressure change process in which a cuff pressure as a pressure in the cuff is changed, a cuff-pulse-wave-amplitude correcting device for correcting the respective amplitudes of the respective pulses of the cuff pulse wave, according to a predetermined non-linear relationship between difference between cuff pressure and subject's mean blood pressure, and amplitude of cuff pulse wave, and a blood-pressure determining device for determining a blood pressure of the subject based on a change of the corrected amplitudes of the cuff pulse wave.
