Abstract
The invention provides a controller and method for deriving a measure of arterial compliance based on an acquired arterial volume variation signal and an acquired pulse arrival time signal. An oscillometric blood pressure measurement device is used to acquire the arterial volume variation signal. Arterial volume and variation in pulse arrival time are both measured as an applied pressure to an artery are varied by the oscillometric blood pressure measurement device. The arterial volume signal is transformed into a corresponding signal representative of variation in peak-to-peak amplitude of the arterial volume.
