ASC: Educational Anesthesia Simulator with Expert System

  • Howard A. Schwid

Abstract

ASC, the Anesthesia Simulator Consultant, is an educational computer program for anesthesia and intensive care medicine. The program combines a real-time graphical simulator with a rule-based expert system. The expert system outlines the anesthetic considerations for simulated patients and provides a suggested anesthetic management plan. The system evaluates the status of the simulated patient intraoperatively, providing detailed analysis of the electrocardiogram, vital signs, airway, arterial blood gas, fluid requirements and critical incidents. During abnormal physiological states, the expert system lists a differential diagnosis and then highlights the most likely cause(s) for the disturbance. The expert system was designed to assist anesthesiologists in understanding and analyzing their clinical decision-making processes by providing immediate instructional feedback on simulated case management. The combination of the expert system and the simulator provides a self- contained educational environment which allows anesthesiologists to practice the management of difficult cases and receive tutorials on their management.
