21. A method for providing humidification for a breathing assistance system, the method comprising:
-
at least partially filling a first volume with a liquid, the first volume communicatively coupled to a second volume housing an absorbent material such that a portion of the liquid flows from the first volume to the second volume and is absorbed by the absorbent material; and applying heat to the second volume such that liquid in the absorbent material evaporates for delivery toward a patient, wherein additional liquid flow from the first volume to the second volume for absorption by the absorbent material results at least in part due to the evaporation of the liquid from the absorbent material. - View Dependent Claims (22)
