Input Impedance of the Arterial System Using Parametric Models

Abstract : In this work, we propose to use parametric models for the estimation of arterial tree input impedance. The results of this new method are compared with those of the standard method based on the Fast Fourier Transform (FFT). The comparison is first made with pressure and flow measurements on a calf, then with human blood pressure measurements completed by blood flow data simulated from a soliton+windkessel model. The input impedance is calculated both at aorta and finger. As illustrated by the numerical results, the advantage of the proposed parametric method is its smooth impedance estimations, whereas the standard FFT method yields more disturbed results.
