A method and an apparatus for monitoring a sedated patient, the method comprising the steps of providing a skin conductance signal measured at an area of the patient's skin through a time interval, establishing the existence of at least two fluctuation peaks in the skin conductance signal through said time interval, considering if the amplitudes of fluctuation peaks in the skin conductance signal through said interval, the basal level of the skin conductance signal through said interval and the width of the fluctuation peaks in the skin conductance signal fulfils a predetermined criterion, activating a first output signal which indicates the state of awakening in the patient if said criterion is fulfilled, and activating a second output signal which indicates the state of pain in the patient if said criterion is not fulfilled.
La présente invention concerne un procédé et un appareil de surveillance de patient sous sédation. Le procédé consiste à prendre un signal de conductance de la peau mesurée sur une surface de la peau du patient à intervalles réguliers, à établir l'existence d'au moins deux pointes de fluctuation dans le signal pendant l'intervalle considéré, à vérifier si les amplitudes des pointes de fluctuation du signal dans cet intervalle, le niveau de base du signal dans l'intervalle, et la largeur des pointes du signal satisfont à un critère défini, à activer un premier signal de sortie qui indique l'état d'éveil du patient s'il est satisfait au critère considéré, et à activer un second signal de sortie qui indique l'état de douleur du patient s'il n'est pas satisfait au critère considéré.
