Abstract
The invention relates to a method and a device (110) for administering a humidified aerosol (112) to a patient interface (114) by : a) providing a first gas flow (118) comprising a humidified aerosol; b) providing a second gas flow (126) comprising humidified respiratory gases (128); c) providing a liquid flow (134) of a thermally balancing liquid (136); d) thermally balancing the first and second gas flow by parallel guiding the first and second gas flow, wherein the first and second gas flow are guided in a manner that they are at least partially surrounded by the liquid flow of the thermally balancing liquid; e) mixing the first and second gas flow, whereby enriched respiratory gases (142) comprising the humidified aerosol are obtained; and f) administering the enriched respiratory gases to the patient interface. This avoids a redrying of the humidified aerosol, thus inhibiting a blockage of the patient interface.
