ABSTRACT:
An assembly includes a nasal cannula with nostril outlet prongs and a pair of oxygen inlets. A pair of oxygen feed lines are connected at one end to the cannula inlets and at their other ends are adapted for connection to an oxygen tank. Soft, flexible face guards are attached to portions of the cannula running across the face of the patient, and are positioned so as to lie generally adjacent to the cheek of the patient. The face guards, which may be permanently or temporarily attached to the cannula, distributes the force of the cannula against the patient's skin so as to minimize or eliminate skin impressions.
