Abstract :
A method for the noninvasive measurement of the vascular properties at level of the brachial artery is presented. The method uses noninvasive recordings of arterial blood pressure and flow carried out at different sites to estimate the transfer function between the two signals. A transmission-line model is used to fit the estimated transfer function and to extract the parameters of interest. Measurements of arterial compliance and peripheral resistance, were extracted from normal subjects in different physiological experimental conditions
