This paper presents a prototype virtual reality (Vp) system for training
medical first responders. The initial application is to battlefield
medicine and focuses on the training of medical corpsmen and other
front-line personnel who might be called upon to provide emergency
triage on the battlefield. The system is built upon Sandia's multiuser,
distributed Vp platform and provides art interactive, immersive
simulation capability. The user is represented by an Avatar and is able
to manipulate his virtual instruments and carry out medical procedures.
A dynamic casualty simulation provides realistic cues to the patient's
condition (e.g. changing blood pressure and pulse) and responds to the
actions of the trainee (e.g. a change in the color of a patient's skin
may result from a check of the capillary refill rate.) The current
casualty simulation is of an injury resulting in a tension pneumothorax.
This casualty model was developed by the University of Pennsylvania and
integrated into the Sandia MediSim system.
