A NOVEL MULTI-ELEMENT, FOUR-PARAMETER WINDKESSEL MODEL OF THE ARTERIAL TREE

Windkessel models of the arterial tree play an important role in clinical practice as well as in prescribing the boundary conditions of one and three-dimensional simulations of blood flow. Such models should describe the main features of the arterial tree (compliance, resistance, inertance and energy dissipation) realistically by using the smallest possible number of parameters. All existing windkessel models consist of a few basic elements modeling inertance, compliance and resistance of the arterial tree, and they can describe the arterial input impedance realistically, but they can model neither the pulse pressure nor flow wave attenuation from the arterial inlet to the capillary outlet. The goal of this work is to define a novel tree-like structure windkessel model, with only four free parameters which can also model the pressure and flow wave attenuation toward the arterial periphery.
