For use with Spacelabs Capnography Modules (91517) in sidestream mode. The airway T-adapter connects into an infant sized breathing circuit to allow sidestream sampling of exhaled CO2 gases. The sampling line includes a section of Nafion, which is used to help evaporate moisture from the sampling line, allowing the water trap to collect less water and increase overall time of use per adapter. The sampling line has an integrated water trap and bacteria filter that connects directly to the module. Use only as directed. Single-patient use. Box of 10 pieces.
