Abstract:
An apparatus for successively estimating an intraarterial blood pressure of a living subject, based on information non-invasively obtained from a circulatory organ of the subject, comprising:first means for non-invasively obtaining, from the circulatory organ of the subject, first information which relates to velocity of propagation of a pulse wave which propagates through an artery of the subject;second means for non-invasively obtaining, from the circulatory organ of the subject, second information which relates to an area defined by a volume pulse wave from a peripheral portion of the subject; andthird means for estimating, according to a predetermined relationship between (A) blood pressure, and (B1) first information and (B2) second information, the intraarterial blood pressure of the subject, based on the first information obtained by the first means and the second information obtained by the second means.
