Combat Emergency Medicine Expert System (CEMES): Project Phase 2 Report

摘要

This report outlines the project's rationale and documents the major design concepts underlying the exploratory development of Combat Emergency Medicine Expert System (CEMES). CEMES is an expert system designed to perform automatic diagnosis and treatment of hemorrhagic shock with or without concurrent chemical agent contamination. Its anticipated use is as a forward-area medical aid, operating automatically following initial hands-on first-aid and system attachment by a medic, medic extender, or physician. A laboratory prototype CEMES has been designed and developed as a totally self-contained, closed-loop system. It monitors vital signs through noninvasive sensors and determines a diagnosis through vital sign and analysis. It analyzes medical trends based on diagnostic and vital sign changes, and both warns for and guards against catastrophic or gradual deterioration in casualty condition. CEMEs advises personnel as to when to initiate IV or drug delivery line, and then automatically manages IV fluid infusion and periodic or continuous drug treatments based on current diagnosis and trends. CEMES monitors its own logistical status, advising as to when IV fluid is getting low and bag replacement is necessary. The logistical analysis watches for inoperative or malfunctioning sensors to facilitate degraded mode operation. CEMES also maintains a diagnostic and treatment history for examination by a physician at a definitive care facility. A color graphics display is used to present system information. Sensor data is simulated through off-the-shelf patient simulators and custom-designed simulation equipment.
