An Intelligent Alarm System Based on Temporal Episodes for Intensive Care Units
نویسندگان
چکیده
This paper presents an alarm system based on temporal episodes. A temporal episode is semi qualitative information that describes the signal trend. The system developed is a limit alarm system based on episodes extracted on line. It is able to recognize specific signal behaviours such as probe disconnection or steady state near the alarm limit threshold. The system is implemented to run on line and was tested on 36 hours of data recorded on adult patients hospitalized in Intensive Care Units. The alarm periods generated are compared to those raised by a classical limit alarm system. The conclusion is that 33% of the alarms raised by the classical system would be filtered, without any clinically relevant alarm missed. Copyright © 2005 IFAC

Design and Implementation of a Fuzzy Intelligent System for Predicting Mortality in Trauma Patients in the Intensive Care Unit
Introduction: The intensive care unit is one of the most costly parts of the national health sector. These costs are largely attributable to the length of stay in the intensive care unit. For this reason, there are significant benefits in predicting patients' length of stay and the percentage of deaths in intensive care units. Therefore, in this study, a fuzzy logic based intelligent system was...

The lack of effective data integration and knowledge representation in patient monitoring limits its utility to clinicians. Intelligent alarm algorithms that use artificial intelligence techniques have the potential to reduce false alarm rates and to improve data integration and knowledge representation. Crucial to the development of such algorithms is a well-annotated data set. In previous stu...
