A minimal cardiovascular system haemodynamic model for rapid diagnostic assistance
Characterising circulatory dysfunction and choosing a suitable treatment is often difficult, and time consuming. This paper outlines a numerically stable minimal model of the human cardiovascular system (CVS) specifically aimed for rapid, on site modelling to assist in diagnosis and treatment. A minimal number of governing equations and a realistic valve law are used to accurately capture trends in CVS dynamics. The model is shown to have long-term stability and consistency with non-specific initial conditions. Results show that the model adequately provides appropriate magnitudes and trends for a variety of physiologically verified test cases.
