Abstract

Procédé et appareil fournissant une mesure de la profondeur d'anesthésie. Une série d'ondes R est analysée au moyen de statistiques cycliques pour en obtenir une mesure de longueur de vecteur représentant la variation R-R de l'échantillon. Le Test Rayleigh est appliqué pour déterminer une longueur de vecteur de référence à partir d'un niveau de probabilité prédéterminé et du nombre d'ondes R dans la série analysée. La mesure de longueur de vecteur est comparée à la longueur de vecteur de référence pour obtenir une mesure de la profondeur de l'anesthésie.
