This software is a game designed to simulate the decision making process of an emergency or ICU physician. It contains a database of patient-types (each with a particular disease) consisting of a set of vital and physical exam signs, and predetermined responses to the players actions. These parameters are set for each patient based on each disease’s pathology. The player has a series of actions and investigations from which to choose. The game’s object is to respond appropriately (with proper actions and proper timeframe) to the vital signs and parameters presented, according to basic principles of pathophysiology as well as current guidelines in resuscitation medicine. The use is as an educational device and a diverting game that medical professionals may use to learn the basics of resuscitating critically ill patients suffering from severe, potentially lifethreatening issues. The game offers on demand, probabilistically generated scenarios encompassing life threatening issues that can arise in an emergency situation right at one's computer monitor at any time, without a sim tech or instructor. It teaches basic guidelines of how to stabilize patients appropriately before they get definitive care and how to generate the line of communication for the patient to get the type of definitive care needed. The software creates a probabilistic engine that "throws" patients at the player in a distribution consistent with typical epidemiological patterns. Because a player must respond to both the parameters generated as well as aspects of the underlying disease, a player may respond differently to the same patient, consistent with real life. Also in contrast to other simulation games the simplicity of the graphical interface and the modularity of our patienttypes and coding allow us to constantly update our game.
