Method and device for estimating the pulse pressure of the central artery using a cuff pressure pulse wave vibration signal

摘要

The present invention relates to a method for estimating central aortic pulse pressure by cuff pressure pulse wave oscillation signals, comprising: (I) providing an equation for estimating central aortic pulse pressure; (II) measuring pressure pulse wave oscillation signals in a cuff, which comprises brachial systolic blood pressure and 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 by the systolic blood pressure and diastolic blood pressure; (IV) analyzing the calibrated pressure pulse wave oscillation signal waveform to obtain a plurality of characteristic values, which are regarded as predicting variables; and (V) obtaining the estimate of central aortic pulse pressure by values of the predicting variables in step (IV) and the equation in step (I). The present invention further provides a device for estimating central aortic pulse pressure by the method of the present invention.
