Abstract :
A frequently used model of the arterial system is the three-element modified Windkessel. The elements of the model are generally assumed to be constant, although it is known that the arterial compliance varies with pressure. A computer simulation of the modified Windkessel model using a pressure-dependent compliance was used to predict stroke volume. The results show a linear correlation between the predicted stroke volume and the measured stroke volume
