Abstract
A method and device for estimating central aortic pulse pressure by cuff pressure pulse wave oscillation signals. The method comprises (I) providing an equation for estimating central aortic pulse pressure; (II) measuring pressure pulse wave oscillation signals in a cuff, which comprise a brachial systolic blood pressure, a diastolic blood pressure and a waveform of the pressure pulse wave oscillation signals in the cuff; (III) averaging the waveform of the pressure pulse wave oscillation signals and calibrating the averaged waveform; (IV) analyzing the calibrated pressure pulse wave oscillation signal waveform to obtain a plurality of predicting variables; and (V) obtaining an estimate of the central aortic pulse pressure by values of predicting variables in step (IV) and the equation in step (I).
