Bioengineering Study of the Human Cardiovascular System.
Abstract
A simplified physical model of the left ventricular loop of a human cardiovascular system was designed and constructed for the purpose of studying certain mechanical aspects of fluid flow in such systems. The model is described in detail and particular attention is given to the analogue of the left ventricle and its driving system. The use of specially designed devices which serve as analogues of resistance and capacitance in the prototype are described and discussed. Compliance of tubing and its effect on flow in the model system is analyzed fully. The rather amazing effect of variation of this physical variable on pump performance is studied and experimental results presented. Pressure wave velocity in the system has been determined and some results are indicated. A discussion of the relationship of the wave velocity to the general problem of flow in elastic tubes is given in some detail. An introductory study has been made of the effect of bleeding on system performance and preliminary results are given. (Author)
