A rule-based system for vital sign monitoring in intensive care

The implementation of a knowledge-based expert system to check on inpatients' conditions is described. In our development of a bedside computerized ICU, graphical user interface (GUI) and graphical visualization have been extensively exploited to facilitate the natural and effective representation of clinical information for patient care, the transition from the manual system to computerized system and users interaction with the system. The input comprises the heart rates, the blood pressures, and the central venous pressures of several inpatients.The algorithm is made up of two parts. The first one, written in C acquires and classifies the data. The second part compares the classified data with the medical information stored in its data base, and draws a conclusion regarding the patient's condition. C Language Integrated Production System (CLIPS) 5.0 is the knowledge-based expert system utilized. The results obtained from the Expert system are displayed using the Simple Raster Graphics Package (SRGP). This system has been implemented and tested on a variety of inputs, and the results are depicted
