Abstract
A nasal cannula is provided having a first and second nasal plug connected to a gas supply such as oxygen. A holder frictionally engages each nasal plug and a connector connects the two holders. The plugs are movable along the length of the connector to allow adjustment of the spacing between nasal plugs to accommodate a person's nostrils but with sufficient friction to retain the selected position. The plugs are rotatable around the longitudinal axis of the connector to adjust the orientation of the plug within a nostril relative to a patient's face, but with sufficient friction to retain the selected position. One of the connector or holder is removably fastened to the patient's face. A regulator is interposed in the gas supply to vary the flow rate and pressure to meet predetermined patterns.
