Combat medical informatics: present and future.

In this paper, we describe a U.S. Army concept to monitor soldier physiologic status and provide computer-based medical support to increase the likelihood of soldier survival on the battlefield. Supported by an underlying platform of complex wearable computerized systems, the "Warfighter Physiological Status Monitoring" (WPSM) concept consists of an array of biosensors embedded in the soldier's uniform integrated with a database management system and a decision support system that will provide assistance in casualty prevention and casualty management. We discuss the main components of the WPSM, its present status, key requirements and outstanding challenges, and near- and far-term research directions.
