Body Simulation for Anesthesia is an interactive PC-based multi-media software program. It is a simulation of the anesthesia work environment that is centered around a sophisticated mathematical model of human physiology and pharmacology. The program provides a multimedia presentation of the patient and the anesthesia workstation such that users may interact with the software to do actions that would be done during an anesthetic case. The goal of the software is to provide users with the opportunity to run through the all intellectual motions, to the extent limited by a multimedia simulation, that would normally be routine, or not so routine, during the anesthetic delivery process.
