Description
Summary:This paper demonstrates an objective method to measure arterial resistance and compliance in humans from ar-terial vascular impedance. Conventional approaches use linear velocity to calculate the impedance spectra. We have presented a method to compute volume-flow using the area of cross-section and doppler shifted frequency, synchronously recorded along with the intra-arterial pressure. Arterial vascular impedance is calculated as the ratio of arterial pressure to volume-flow. A three-element Windkessel model has been employed to estimate the lumped parameters representing the arterial tree.
