An extremely versatile and realistic patient simulator forms the core of the two software programs: SimBioSys Physiology Labs and SimBioSys Clinics. The programs are available on CD-ROM or diskettes. They require the CD-ROM only for installation, so speed of the drive is irrelevant. Only 4-10 MB of hard drive space is actually needed for installation (other requirement above).

With Physiology Labs, the user studies preprogrammed exercises dealing with cardiac function, autonomic circulatory control, oxygen exchange, carbon dioxide exchange, respiratory mechanics, and peripheral oxygen transport. The simulator generates the data, and the exercises lead the student through a series of clinical interventions. To fully appreciate the exercise, the student must observe and record the effects produced in the simulated patient. In the exercises, constraints are sometimes placed on patient physiology to illustrate certain principles more clearly. For instance, autonomic control of cardiac function is interrupted to demonstrate the effect of hemorrhage on venous return and cardiac output without compensation. The exercise is then repeated with the autonomic compensatory mechanisms intact. In this dramatic way, the effects and limits of compensation can be identified and quantitated without harming an animal or patient. The value of any simulator is that the experimental treatment can be altered and the effects of these actions investigated under identical patient conditions.
