Abstract

La présente invention concerne un dispositif à base d'ondes cérébrales et un procédé de surveillance d'anesthésie et de sommeil, qui peut surveiller la profondeur d'anesthésie et la phase de sommeil d'un patient sur la base de signaux d'ondes cérébrales d'un patient. Le dispositif peut comprendre : une unité de mesure d'ondes cérébrales pour mesurer des signaux d'ondes cérébrales d'un patient ; une unité de génération d'informations d'anesthésie et de sommeil pour générer des informations de profondeur d'anesthésie ou des informations de phase de sommeil du patient sur la base des signaux d'ondes cérébrales mesurés ; une unité d'entrée d'utilisateur pour demander la génération des informations de profondeur d'anesthésie ou des informations de phase de sommeil ; et une unité de commande pour commander l'unité de génération d'informations d'anesthésie et de sommeil. L'unité de commande peut effectuer une commande de sorte que l'unité de génération d'informations d'anesthésie et de sommeil applique une stimulation à basse fréquence au patient pour générer les informations de profondeur d'anesthésie du patient lorsque la génération des informations de profondeur d'anesthésie est demandée à partir de l'unité d'entrée d'utilisateur, et peut effectuer une commande de sorte que l'unité de génération d'informations d'anesthésie et de sommeil génère les informations de phase de sommeil lorsque la génération des informations de phase de sommeil est demandée depuis l'unité d'entrée d'utilisateur, de façon à ajuster l'environnement de respiration artificielle du patient sur la base des informations de phase de sommeil générées.
