A model of pulmonary circulation based on Olansen et al. (2000) and Lu et al. (2001). A model of pulmonary circulation in which a right ventricle input pressure pulse drives blood flow through vascular components.
This is a model of pulmonary circulation based on Olansen et al. (2000) and Lu et al. (2001). A right ventricle input pressure pulse drives blood flow through the following vascular components: proximal pulmonary artery, distal pulmonary artery, pulmonary arterioles, pumonary capillaries and pulmonary veins. All of these compartments are modeled as windkessels, with single resistance and compliance parameters. The proximal and distal pulmonary artery segments are also characterized with inertance parameters. Parameter values for distal pulmonary inertance and radial flow resistance were not provided in Lu et al. (2001)
