Blood pressure and Cardiac Output result from the interaction of the heart and arterial load. However, quantitative information about the contribution of both the heart and arterial load to pressure and flow under different physiological conditions and during various diseased states is limited. To quantitatively analyze the cardiac and arterial contributions to systolic and diastolic pressure and Stroke Volume, we make use of the simplified descriptions of the cardiac pump and the arterial load. The heart is described by the varying elastance model (Chap. 13), and the arterial system is described by the three-element Windkessel model (Chap. 24). Using these models the contribution of each parameter to pressure and flow can be quantified.
