ABSTRACT:
A blood pressure monitor system for monitoring blood pressure of a living subject, including a pulse wave detecting device detecting a first pulse wave produced from an artery of the subject via a body surface of the subject over the artery, an inflatable cuff pressing a body portion of the subject, a blood pressure measuring device measuring a systolic and a mean blood pressure of the subject, based on variation in amplitude of pulses of a second pulse wave transmitted to the cuff by changing a pressure in the cuff, and a blood pressure determining device determining a relationship between blood pressure and pulse wave magnitude, based on the systolic and mean blood pressure values measured by the blood pressure measuring device and an upper-peak magnitude and a mean magnitude of the first pulse wave detected by the pulse wave detecting device, and continuously determining, according to the relationship, blood pressure values of the subject based on magnitudes of the first pulse wave detected by the pulse wave detecting device.
