Abstract: A heated breathing circuit with radiant barrier is provided. The breathing circuit includes an airflow conduit configured to receive gas at an input end and configured to deliver the gas to a patient at an output end, a heating element disposed inside the airflow conduit configured to heat the gas inside the airflow conduit between the input end and the output end and a heat shield disposed between the heating element and an outside surface of the airflow conduit such that the heat shield prevents heat energy loss from within the airflow conduit.

Abstract: The disclosure is directed to an example of a device configured to be in fluid communication with an article. The device includes an element configured to contact the article to form a variable compression interface between the element and the article. The device also includes a seal disposed on the element and at the variable compression interface. The seal is configured to reduce an amount of unwanted fluid leakage at the variable compression interface. An example seal includes a filter media configured to trap unwanted particles attempting to pass through the variable compression interface. In one example, the variable compression interface can be included within a heat and moisture exchange (HME) unit.
