news. If you create conditions incompatible with life, the program lets you know your patient is dead, this is the MacMan equivalent of crashing your airplane in a flight simulator, and should this happen you merely start again, because there is no equivalent to reversing the program and resurrecting the dead. Some of the experiment options include: cutting the buffer nerves, resetting baroreceptor function to that expected of a moderately hypertensive subject, and working changes in any of the following: the systemic arterial and/or venous resistance, the cardiac pump performance, mean intrathoracic pressure, the blood volume, and the venous capacitance. Usually you can predict what will happen from what you know about physiology, when you change one factor only. The real value of the program comes when you change one factor only. The real value of the program comes when you change two or more factors simultaneously, which sometimes leads to unexpected results. This conclusion may, of course, be due to my rusty physiology, but I suspect most physicians and physiologists would find educational value in making multiple changes and seeing what happens. Our built-in compensatory mechanisms are impressive. Indeed, the program may make you agree with the Psalmist (139:14) that we are "fearfully and wonderfully made." In conclusion, MacMan is, for the proper hardware, a clean, simple, yet instructive physiologic simulation which is highly recommended.
