Extension tubing adds distance between your oxygen concentrator and your nasal cannula – the machine stays plugged in at one point while you move around the home. Setup: connect one end to the concentrator outlet (or humidifier bottle outlet), join the other end to your cannula using a tubing connector, and set your prescribed flow as normal. Tubing length guidance: most 5 L home concentrators support a total tubing run of up to about 15 m. Beyond the manufacturer’s recommendation, oxygen delivery pressure can drop – check your machine’s manual or ask us if unsure.
