ABSTRACT:
A method and an apparatus for measuring blood pressure of a subject by using a pulse wave sensor for detecting pulse wave produced from an arterial vessel of the subject, and pressing device for pressing the pulse wave sensor against the arterial vessel via a body surface of the subject, the method comprising the steps of pressing the pulse wave sensor against the arterial vessel with a continuously variable pressing force produced by the pressing device, detecting variation in magnitude of the pulse wave with the pulse wave sensor while the pressing force of the pressing device is continuously varied, and determining blood pressure of the subject based on the detected magnitude variation of the pulse wave.
