Title (EN) SYSTEM AND METHOD FOR MONITORING AUTOREGULATION UTILIZING NORMALIZED REGIONAL OXYGEN SATURATION VALUES
(FR) SYSTÈME ET PROCÉDÉ DE SURVEILLANCE D'AUTORÉGULATION UTILISANT DES VALEURS DE SATURATION EN OXYGÈNE RÉGIONALE NORMALISÉES
Abstract: front page image
(EN)A method for monitoring autoregulation includes, using a processor, receiving a blood pressure signal an oxygen saturation signal, and a regional oxygen saturation signal from a patient. The method also includes normalizing the regional oxygen saturation signal to correct for variation in the oxygen saturation signal based on a relationship between the oxygen saturation signal and the regional oxygen saturation signal. The method further includes determining a linear correlation between the blood pressure signal and the normalized regional oxygen saturation signal. The method still further includes providing a signal indicative of the patient's autoregulation status to an output device based on the linear correlation.
(FR)L'invention concerne un procédé de surveillance d'autorégulation qui consiste, au moyen d'un processeur, à recevoir un signal de pression sanguine, un signal de saturation en oxygène et un signal de saturation en oxygène régionale provenant d'un patient. Le procédé consiste également à normaliser le signal de saturation en oxygène régionale pour corriger une variation du signal de saturation en oxygène sur la base d'une relation entre le signal de saturation en oxygène et le signal de saturation en oxygène régionale. Le procédé consiste en outre à déterminer une corrélation linéaire entre le signal de pression sanguine et le signal de saturation en oxygène régionale normalisé. Le procédé consiste en outre à fournir un signal, indiquant l'état d'autorégulation du patient, à un dispositif de sortie sur la base de la corrélation linéaire.
