Abstract
A nasal cannula is disclosed which may be easily and quickly adjusted to custom fit individual wearers. The nasal cannula comprises lengths of tubing with the ends formed to provide narine tubes which project into the nares of the wearer, and does not have any cavity-forming structure which might promote growth of bacteria or result in resonant flow noises. The formed ends of the tubing are secured to a formable bridge or saddle which spans the distance between the narine tubes, whereby the angular position as well as the spacing between the narine tubes may be quickly and easily adjusted by suitably forming the bridge.
