A system and method of providing bi-level CPAP therapy is provided that incorporates an infrared carbon-dioxide sensor (124) to determine whether a patient is inhaling or exhaling. Patient exhalation causes the infrared light to be absorbed, while patient inhalation reduces the presence of carbon- dioxide causes little or no absorption of carbon-dioxide. The level of carbon- dioxide in an associated patient breathing interface is monitored for thresholds that trigger higher CPAP pressure upon inhalation and lower CPAP pressure upon exhalation.

La présente invention concerne un procédé et un système de thérapie à ventilation spontanée en pression positive continue à deux niveaux, mettant en oeuvre une sonde infrarouge pour le dioxyde de carbone permettant de savoir si le patient inspire ou expire. L'expiration est marquée par une absorption de l'infrarouge, alors que l'inspiration fait descendre la teneur en dioxyde de carbone, ce qui amène une absorption très faible voire nulle de dioxyde de carbone. Le niveau de dioxyde de carbone dans l'interface respiratoire associée au patient est l'objet de seuils de détection déclenchant un niveau haut de pression de ventilation spontanée en pression positive continue à l'inspiration et un niveau bas de pression de ventilation spontanée en pression positive continue à l'expiration.
