Abstract: front page image
(EN)The present invention provides for an improved method of determining a water out condition in a humidified gases supply apparatus. The method includes a two step process including a primary determination of a water out condition and a secondary determination of a water out condition. This primary determination is made during observation of the normal operation of the apparatus. During the secondary determination the method takes temporary control over the humidifying part of the apparatus. The secondary determination confirms or contradicts the primary determination.
(FR)La présente invention porte sur un procédé amélioré de détermination d'une condition d'épuisement d'eau dans un appareil d'alimentation en gaz humidifiés. Le procédé comprend un processus en deux étapes comprenant une détermination primaire d'une condition d'épuisement d'eau et une détermination secondaire d'une condition d'épuisement d'eau. Cette détermination primaire est réalisée pendant l'observation du fonctionnement normal de l'appareil. Pendant la détermination secondaire, le procédé prend un contrôle temporaire sur la partie d'humidification de l'appareil. La détermination secondaire confirme ou contredit la détermination primaire.
