Abstract
A moisture removal apparatus for a breathing circuit includes a breathing gas conduit for receiving a flow of breathing gas having a first humidity level. A dry gas conduit is provided adjacent to at least a portion of the breathing gas conduit for receiving a flow of dry gas having a second humidity level lower than the first humidity level. A heating element extends from an upstream end of the breathing gas conduit to a downstream end of the breathing gas conduit. The heating element provides heat to the flow of breathing gas such that the breathing gas at the downstream end is heated to a higher temperature than the breathing gas at the upstream end. A moisture transmission pathway enables transfer of moisture from the breathing gas to the dry gas based on the humidity differential.
