Abstract
A blood pressure monitor apparatus for monitoring a blood pressure of a living subject, including a blood-pressure measuring device which includes an inflatable cuff adapted to be wound around a body portion of a living subject and measures a blood pressure of the subject by changing a pressing pressure of the cuff to not lower than a systolic blood pressure of the subject, a cuff-pressure control device which iteratively changes, after a predetermined rest period following the blood pressure measurement of the blood-pressure measuring device, the pressure of the cuff to a predetermined value lower than the systolic blood pressure of the subject, and a blood-pressure-change identifying device for identifying a change of the blood pressure of the subject based on (a) respective amplitudes of first heartbeat-synchronous pulses obtained from the cuff during the blood pressure measurement of the blood-pressure measuring device, (b) respective pressures of the cuff when the first pulses are obtained, (c) respective amplitudes of second heartbeat-synchronous pulses obtained from the cuff during each of the iterative changings of the cuff pressure by the cuff-pressure control device, and …
