Abstract
A blood pressure monitor including a cuff, a pressure sensor which detects a pressure in the cuff, a pressure regulating device which increases the pressure of the cuff, a pulse-amplitude determining device for determining an amplitude of each of pulses of a pulse wave which are produced in the cuff and detected by the pressure sensor while the cuff pressure is increased, a candidate determining device for determining, as a diastolic BP candidate, a pressure of the cuff which is detected by the pressure sensor and which corresponds to an amplitude of a first pulse of the pulses determined by the pulse-amplitude determining device, by judging whether the amplitude of the first pulse is not greater than a reference value which is smaller than an amplitude of at least one second pulse of the pulses, by a predetermined proportion of the amplitude of the second pulse, the amplitude of the second pulse being determined by the pulse-amplitude determining device after the amplitude of the first pulse is determined, and a BP determining device for determining, as a monitor diastolic BP value, the cuff pressure corresponding to the amplitude of the first pulse, when the candidate determining device determines, as the diastolic BP candidate, the cuff pressure corresponding to the amplitude of the first pulse, with respect to a predetermined number of the one or more second pulses.
