Abstract

A swivel elbow includes a conduit pathway separated from a vent airflow pathway for conducting respective gas flow streams in use. The swivel elbow further includes baffle structure that separates the respective gas flow streams so that they do not interfere with each other within an interior (e.g., breathing chamber) of a mask to which the elbow is connected in use.
