ABSTRACT An apparatus for measuring arterial elasticity includes a cuff member having a light source and light detector, a variable pressure generating device, a fluid pressure sensor, a digital signal process or and a difference detecting element. The fluid pressure in a fluid pressure chamber in the cuff member is varied by a variable fluid pressure generating device. The digital signal processor responds to the output of the fluid pressure sensor and the output of the difference detecting element and delivers a digitally processed signal corrosponding to an arterial volume change based on a simulated arterial elasticity. The arterial elasticity and the frequency characteristic thereof are derived based on the operation of the digital signal processor.
