A computer-controlled patient simulator.

Sim One, a computer-controlled manikin, demonstrates the feasibility of using a simulator to teach medical students, interns, and residents some of the manual skills they must learn. The simulated patient looks like a living person, "breathes" with chest and abdomen, has carotid and temporal pulses synchronous with an audible heartbeat, and can be ventilated by bag and mask or through an endotracheal airway. "He" also responds appropriately when oxygen, nitrous oxide, thiopental sodium, succinylcholine, and either of two vasopressors are given by the student. Each maneuver of the student and each response of the simulated patient are recorded and available in typed and graphic form for immediate reinforcement of the learning experience.
