Abstract
A moisture removal apparatus for a breathing circuit may include a breathing gas conduit configured to receive a flow of breathing gas having a first humidity level. The apparatus may include a dry gas conduit adjacent to at least a portion of the breathing gas conduit, the dry gas conduit configured to receive a flow of dry gas having a second humidity level lower than the first humidity level. The apparatus may also include a feeding conduit extending through at least a portion of the dry gas conduit, the feeding conduit configured to introduce the dry gas into the dry gas conduit. The apparatus may further include a moisture transmission pathway configured to enable transfer of moisture from the breathing gas to the dry gas based on the humidity differential.
