PURPOSE:To monitor surely condition of circulation of a living body by an apparatus wherein each repeatedly measured blood pressure value and the dimension of the synchronous wave of heart pulse when each blood pressure value is measured are graphically displayed along a common time axis on the displaying face of a display. CONSTITUTION:A pressure sensor 12, a rapidly evacuating valve 14, a slowly evacuating valve 16 and a pneumatic pump 18 are connected with a cuff 10 provided with an expansion bag wound on the upper arm part of a living body and pressing this cuff 10 through a pipeline 20 and a pressure signal expressing the pressure in the cuff 10 detected by means of a pressure sensor 12 is fed to a cuff detecting circuit 22 and a pulse detecting circuit 24. In addition, the continuously measured blood pressure values are successively displayed on a displaying face 44 of a display 38 and the valve of amplitude is determined by a max. amplitude determining means at a pulse of the max. amplitude when the blood pressure width is determined and it is graphically displayed on the time axis being common with the blood pressure value on the displaying face. It is possible to make sure monitoring of the kinetic condition of circulation of a living body by comparing the blood pressure value with the value of amplitude of the pulse wave like this. |
