The threeelement windkessel model was introduced by westerhof et al. Windkessel effect, used in medicine is a term, to account for the shape of the arterial blood pressure waveform in terms of the interaction between the stroke volume and the compliance of the aorta and large elastic arteries windkessel vessels. Moreover, this paper relates the measurements and patient specific factors of age, sex, smokingfitness habits and drug use with the lumped parameters of the windkessel theory in a simple way, and allows even a nonexpert to compare the measured arterial pressure with the expected pressure of the model by simply altering the model inputs.
