ABSTRACT:
A measuring device to measure vascular function of an artery includes a cuff that is attachable to a specified part of a body to constrict the artery, a pulse wave amplitude calculating device that calculates an amplitude of a pulse wave that is synchronous with a heartbeat and is based on a change in a volume of the artery, and an inference device that infers a pressure-to-volume characteristic for the artery based on the amplitude of the pulse wave and a corresponding pressure. A blood pressure meter incorporating the measuring device uses a measure of the vascular function to determine a degree of sclerosis in the artery.
