られる。According to the present invention, the continuous monitoring of blood pressure fluctuations uses the unloaded and unconstrained PWV method (pulse wave velocity method), and the blood pressure is measured only when a predetermined blood pressure fluctuation occurs. Therefore, continuous blood pressure monitoring can be performed without causing pain to the subject. In addition, blood pressure can be monitored very finely for each beat. Further, since the blood pressure is measured only when a predetermined blood pressure fluctuation occurs, unnecessary blood pressure measurement is not performed. Furthermore, by using the short-time blood pressure measurement method using a single pulse wave for blood pressure measurement, there is an effect that continuous blood pressure monitoring can be performed with a low load (almost no load).
