<p><P>PROBLEM TO BE SOLVED: To provide a blood pressure measurement apparatus, a blood pressure derivation program and a method for deriving a blood pressure capable of accurately deriving the blood pressure based on an occurrence mechanism of a cuff pressure and a pulse save amplitude. <P>SOLUTION: A derivation control section 104 includes an envelope extraction part 113 for extracting an envelope of a volume pulse wave based on an arterial volume signal, a differential processing part 114 for differentiating the envelope with respect to the cuff pressure, a maximum value extraction part 115 for extracting the maximum value of the differential value of the envelope, and a blood pressure determination part 116 for determining the cuff pressure used for the differentiation of the maximum value as the blood pressure. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
