Original Abstract Submitted
an hme for use in providing a flow of breathing gas to a patient includes a housing defining a main passage for conveying the flow of breathing gas therethrough as well as an hme element and a number of valve arrangements positioned within the main passage. each valve arrangement includes a valve passage and a valve member moveable among a first position wherein the passage of gases through the valve passage is prevented and thus flow in the main passage is required to pass through the hme element, and a second position in which the passage of gases through the valve passage is permitted and thus flow in the main passage can bypass the hme element. the positioning of the valve member of each valve arrangement among the first position and the second position is dependent on a flow of gas through the main passage.
