Abstract
An airway adapter comprising a tubular portion having opposing windows in a predetermined spaced configuration. The windows have at least one surface which interacts with moisture condensed thereon from respiratory gases so as to reduce the interference of such condensation with the measurement of constituent gases by a gas analyzer. The surface of the windows can be hydrophobic, hydrophilic, or a combination thereof.
