Abstract

L'objet de la présente invention est de détecter le bruit respiratoire pendant le sommeil d'une personne qui dort à l'état naturel, et de déterminer, avec une excellente précision, un état de consommation d'oxygène, etc. à l'état endormi ou pendant le sommeil sur la base d'un signal détecté pendant le sommeil. La solution selon l'invention consiste à transmettre le signal d'un sujet (2) pendant le sommeil, ledit signal ayant été détecté par un moyen (3) de détection de bruit respiratoire pendant le sommeil, à un appareil (6) d'analyse de bruit respiratoire pendant le sommeil par l'intermédiaire d'un terminal portatif (5). L'appareil (6) d'analyse de bruit respiratoire pendant le sommeil comprend : un moyen d'acquisition de forme d'onde caractéristique de la respiration destiné à traiter le signal pendant le sommeil et à acquérir ainsi une forme d'onde caractéristique de la respiration ; un moyen de différenciation des formes d'onde de respiration destiné à différencier une forme d'onde d'inhalation d'une forme d'onde d'expiration dans la forme d'onde caractéristique de la respiration ; un moyen d'extraction de valeur caractéristique destiné à extraire une ou une pluralité de valeurs caractéristiques sélectionnées parmi la forme d'onde d'inhalation, la forme d'onde d'expiration, chaque intervalle de temps allant de la forme d'onde d'expiration à la forme d'onde d'expiration ou allant de la forme d'onde d'expiration à la forme d'onde d'inhalation, l'intervalle de temps de la forme d'onde d'inhalation, l'intervalle de temps de la forme d'onde d'expiration, la valeur de l'amplitude de la forme d'onde d'inhalation, et la valeur de l'amplitude de la forme d'onde d'expiration ; et un moyen de détermination de l'état destiné, sur la base des valeurs caractéristiques extraites, à déterminer l'état de sommeil du sujet (2), à déterminer un état d'apnée ou un état d'hypopnée ou à estimer un état de consommation d'oxygène.
