Abstract

In many hemodynamic theories, branches are supposed to generate reflection wave and eventually created “2-peak” pressure and flow contours in vivo. We try to study the influence of branches from the transmission efficiency. Pressure and flow contours were measured in rats before and behind the largest branch structure-the aortic bifurcation. All these data were digitized and then analyzed by DFT. Transmission indices were calculated from these Fourier coefficients. The results illustrate that the transmission impedance for pressure wave in the artery system matches perfectly even if the branches exist
