Nasal Cannula Only is a replacement prong-and-tube assembly for patients who need to replace the cannula component of their oxygen system without replacing the connecting tubing. It is appropriate in setups where the supply tubing is in good condition and only the patient-contact portion requires replacement.

Regular cannula replacement is recommended for hygiene reasons. OxyCare supplies nasal cannulas in multiple configurations and lengths, and can include them in regular supply delivery schedules.
