Contribution au développement d'un système d'aide à la surveillance de patients hospitalisés en unités de soins intensifs

Abstract : The work of this thesis is within the general framework of assistance at the monitoring of patients in ICUs. We presented a method of information's extraction from the physiological data, formulated in trend, describing the behaviours of patients in ICUs. This method, developed previously by [Charbonnier, 2005], is based on a qualitative representation of the signais. This representation reduces considerably the quantity of data, which facilitates the work of monitoring of the operator and the assistance to interpret the data. After having made modifications on the trend extraction methodology, we developed a filtering alarms system based, at first, only on the trend representation, where we tried to recognize some clinical events on the various supervised physiological parameters. Secondly, we focused work on alarm filtering occurring on the oxygen saturation (Sp02) signal, used to detect vital problems. The designed system is able to recognize on line severa 1 events occurring on Sp02 and assists the medical staff in its decision process using a multivariable analysis of several physiological parameters.
