ELECTRONIC ANALOG SIMULATION OF THE MAMMALIAN CARDIOVASCULAR SYSTEM.
Abstract
The report is the second in a series that describes work done to simulate the mammalian cardiovascular system using electronic analog computer techniques (See also AD-423 288). Development and evaluation of a second computer model is presented. The second model, like the first, simulates the function of the left ventricle and the systemic circulation; however, the systemic vascular system is assumed to be a twoinstead of a three-element impedance. In addition, an aortic pressoreceptor reflex is incorporated to provide elementary control logic for the system. By means of this reflex, the single-chambered heart is directed to pump automatically when the aortic pressure reaches a predetermined minimum, and the rate at which fluid is pumped from the heart is correspondingly adjusted so that the aortic pressure pulse will peak precisely at a specified maximum. These changes make the second model more realistic than the first; however, lack of quantitative data regarding the cardiovascular system compromises its accuracy. It nontheless gives an insight into the value of systems analysis of physiological systems using computer techniques. (Author)
