CIRCSYST 3.0

Description: Circsyst 3.0 is a simulation program based on ventricular force: impedance and the Guyton right atrial pressure: cardiac output relationships. A tutorial presents a discussion of the factors involved in determining arterial mean, systolic, diastolic and pulse pressure. The last portion of the program provides a series of unknowns which are randomly selected conditions and the user is quizzed on the cause or effect of various conditions. Students can change the subject?s age, ventricular muscle mass, contractility, heart rate, blood volume, and arteriolar resistance, and can deal with the effects of haemorrhage, coronary occlusion, exercise, chronic left ventricular failure, aortic innsufficiency, aortic stenosis, mitral stenosis, mitral regurgitation, arteriovenous shunt, and cardiac tamponade. The program also allows the user to vary arterial resistance, venous resistance, arterial pressure, right atrial pressure, reflection coefficient, permeability-surface area coefficient, initial oncotic pressure, and interstitial pressure.

Comments & References: Menu-driven. Utilizes graphics and colour, requires a colour graphics adapter CGA or equivalent and higher. Previously called Circulatory System . Simulates cardiovascular function. Primarily designed as a review and reinforcement technique for a systemic, organ physiology course. Text is kept to a minimum and the emphasis is placed on graphics and simulations to provide for active participation by the user(s).
