Abstract
A apparatus for measuring blood pressure of a living subject, including a blood pressure measuring device which receives a heartbeat synchronous-signal wave generated by arteries of the patient, determines respective amplitudes of successive pulses of said heartbeat-synchronous signal wave, each of which corresponds to one heartbeat of the subject, and provides as a first series of pulse amplitudes, the pulse amplitudes arranged in order of generation. The device further smoothens the first series of pulses and provides a second series of smoothened pulse amplitudes, and determines a blood pressure value based on a change in the second series. The device further provides a two-dimensional output of the first and second series, where one of the two series is superimposed on the other, and/or a representation of the degree of propriety of the measurement condition during which the measurement was performed.
