Abstract

On the basis of the data in vitro on fluid resistance of a stenosis equations for definition of flow, velocities and the critical degree of a stenosis are offered. Equations take into consideration along with degree of stenosis - peripheral resistance; diameter of artery; parametres of stenosis; ratio offluid resistance for stenotic and collateral parts of the arterial tree; ratio lumen vessels. The impact analysis of these factors on system hemodynamics of arteries allows to conduct the received results.
