Abstract
A blood-pressure monitoring apparatus including an inflatable cuff adapted to apply a pressing pressure to a body portion of a living subject, a cuff-pulse-wave detecting device which detects a cuff pulse wave which is produced in the inflatable cuff when the cuff applies the pressing pressure to the body portion of the subject, a pressure control device which increases the pressing pressure of the inflatable cuff to a predetermined value lower than a mean blood-pressure value of the subject, an index-value calculating device for iteratively calculating an index value indicative of a condition of a circulatory system of the living subject, a starting device for judging whether each of the index values calculated by the index-value calculating device is abnormal and, when the each index value is judged as being abnormal, starting the pressure control device to increase the pressing pressure of the cuff to the predetermined value, and an abnormality judging device for judging whether the subject has an abnormal blood-pressure value, based on at least one of respective amplitudes of heartbeat-synchronous pulses of the pulse wave detected by the pulse-wave detecting device when the pressing pressure of the cuff is increased to the predetermined value by the pressure control device.
