Patent

CA 2280756

A process is disclosed for switching the inspiration or expiration phase during CPAP therapy. A first high threshold value and a second low threshold value enable non-specific influences on the first derivative of the gas flow curve to be suppressed in the corresponding breathing phase and the transition to the next corresponding gas phase to be determined with high sensitivity. The advantages of the invention are a higher switching accuracy and a higher safety for the patient.

Procédé pour faire démarrer la phase d'inspiration ou d'expiration pendant une thérapie par ventilation spontanée en pression positive continue. Une première valeur limite supérieure et une deuxième valeur limite inférieure permettent de supprimer dans la phase d'expiration correspondante des influences non spécifiques sur la première dérivée de la courbe d'écoulement de gaz et de déterminer le passage dans la prochaine phase gazeuse correspondante avec une haute sensibilité. Les avantages de l'invention sont une plus grande précision de commutation et une plus grande sécurité pour le patient.
