Abstract
An apparatus for automatically measuring a blood pressure of a living subject, including a cuff which is wound around a portion of the subject, a cuff pulse wave occurring to the cuff when a pressure in the cuff is changed, a pulse-wave detecting device which is worn on another portion of the subject and detects a volumetric pulse wave, a correction-factor determining device for iteratively determining, for each of respective pulses of the volumetric pulse wave, a correction factor to correct an amplitude of the each pulse to a predetermined value, a first determining device for iteratively multiplying, by the correction factor determined for the each of the pulses of the volumetric pulse wave, an amplitude of one of the pulses of the cuff pulse wave that corresponds to the each pulse of the volumetric pulse wave, and thereby determining a corrected amplitude of the one pulse of the cuff pulse wave, and a second determining device for determining a blood pressure of the subject based on a change of the respective corrected amplitudes of the respective pulses of the cuff pulse wave, with respect to the pressure of the cuff.
