[Physical simulation of radial artery displacement].

A previous developed physical cardiovascular simulation is used to investigate the displacement of radial artery during a cardiac cycle. Simulation result shows that the displacement is much greater than the change in the radius of the radial artery. The result is similar to the clinical observation reported before. Based on the simulation result, it is suggested that the displacement of radial artery plays an important part in the Maixiang (pulse condition), which is one of the most important contents of diagnostics in Traditional Chinese Medicine.

[Simulation study on the blood volume feedback control].

To describe the relationship between blood volume and the cardiac function mathematically, a computer cardiovascular model, was developed including a systemic circulation, a heart and a pulmonary model and a blood volume feedback control. Simulation results indicate that the chronic heart failure could be compensated by increasing the blood volume to maintain the proper arterial pressure. Deterioration in heart failure causes an increase in blood volume, as well as increases in heart volume and cardiac energy consumption. These results are in agreement with the clinical data and results reported in the literature. The simulation also shows that for a predetermined ventricular contractility, an adequate increase in blood volume will increase the heart volume but decrease the cardiac energy consumption and lead the heart to work in an optimum condition.
