Abstract

Un procédé et un appareil pour humidifier un gaz respirable fourni à un utilisateur comprenant la fourniture d'un gaz respirable, la production de l'humidité ou de l'eau provenant du milieu ambiant environnemental, par exemple, par le biais d'une condensation et/ou d'un air déshumidifié, et l'acheminement du gaz respirable le long d'un passage de flux d'air. Le passage de flux d'air comprend éventuellement un accès à au moins une partie de l'humidité ou de l'eau pour augmenter une humidification du gaz respirable, à délivrer à l'utilisateur.
