Arterial segment model evaluation by the means of two port electrical circuit theory — Properties of different arterial segments at various hematocrit values

Abstract

Within this work, the analysis of the selected arterial system segments were performed regarding to various hematocrit values. Properties of arteries were transformed to electrical quantities by using electromechanical analogy. There is theory of two port electrical circuits, which was used for analysis of the selected arterial segments. The characteristic voltage and current transfers were calculated in order determine the atrial properties as function of frequency for the various hematocrit values. The work deals with model of blood viscosity assuming non - Newtonian flow and then combines it with Newtonian blood flow, which is characteristic for the used arterial system model. The impact of different hematocrit values on the selected arterial segments is evaluated.
