in Using your Oxygen Concentrator

How often should I replace my nasal cannula?

Your nasal cannula should be replaced regularly and we recommend doing this on a monthly basis. Single lumen cannula and tubing up to 5m in length is recommended to ensure proper breath detection and oxygen delivery. Problems can occur if your total tubing length exceeds 5m.1

Caution: Using a cannula other than a high flow cannula may restrict oxygen delivery and/or attachment to nozzle fittings.
