<P>PROBLEM TO BE SOLVED: To calculate blood pressure from a pulse wave from which an error caused by a change in the pressurization speed of cuff pressure is eliminated. <P>SOLUTION: An electronic blood pressure meter 100 is provided with: a cuff to be disposed around the periphery of the measurement part of a person to be measured; an adjustment unit for adjusting pressure within the cuff by controlling a pump for supplying fluid into the cuff; a control unit for controlling the adjustment unit so that, during the measurement of blood pressure, the pressure within the cuff is increased at a constant speed according to a target pressurization speed; a pressure detection unit for detecting a cuff pressure representing the pressure within the cuff; a pulse wave detection unit 118 for detecting a pulse wave superposed on the cuff pressure; a blood pressure calculation unit for calculating blood pressure on the basis of the detected cuff pressure and of a pulse wave amplitude; and a target change unit 114 for changing in a variable manner the target pressurization speed. The blood pressure calculation unit changes the pulse wave amplitude so as to correct an error in the pulse wave amplitude caused by a change in the target pressurization speed and calculates blood pressure on the basis of the cuff pressure and the changed pulse wave amplitude. <P>COPYRIGHT: (C)2013,JPO&INPIT |
