The recommended flow rates for a nasal cannula are up to 6 liters per minute for a standard sized adult. Cannulas do come in a variety of sizes and shapes from infant up to high flow cannulas, which can accommodate up to 10 liters per minute. The largest population of oxygen patients using nasal cannulas are on a standard adult nasal cannula at a rate of 2 liters per minute. **So how do you maintain and care for your extension tubing and nasal cannula?**  There are a variety of opinions out there, from wiping down the nasal prongs with alcohol daily, to replacing cannula every 3 months, to rinsing oxygen tubing with soapy water. I’d like to dispel some of the misinformation out there and provide some best practices for optimal maintenance of your tubing and cannula. First let’s start with your oxygen extension tubing. This is the tubing that connects from the oxygen source (concentrator, cylinder, or liquid reservoir) to the nasal cannula and is anywhere in length between 4 feet for portable systems and 50 feet for home use. Since this tubing is basically a “closed system,” which means it is not exposed to a great deal of the surrounding environment, you should replace this tubing every 90 days. In extreme circumstances where the patient is exposed to a highly dusty environment, then changing this tubing more frequently would be recommended. As for the nasal cannula, if you are wearing your oxygen 7 days a week, 24 hours per day, the cannula should be changed every 2 weeks. You can wipe the nasal prongs during those two weeks with a clean cloth that has a mild soap solution, but that is all you need to do. To get something “clean” using alcohol, you would need to continually rub the item for about 20 minutes. Plus, the alcohol will begin to harden those nasal prongs over time. Portable oxygen has its own maintenance timeframes. If you are leaving the home and using your oxygen system daily and for long periods of time, you should be changing your tubing and cannula more frequently than if you were occasionally leaving the home for brief periods of time. An easy rule of thumb: your cannula should never be stiff or discolored. Contact your supplier for new extension tubing and cannulas if that’s the case. Keeping your cannula and tubing well maintained will not only help you feel better, but will help assure that you are receiving the correct amount of prescribed oxygen. - [Tweet](https://twitter.com/share) [Oxygen Safety](https://blog.oxygo.life/tag/oxygen-safety) / [Oxygen Tips](https://blog.oxygo.life/tag/oxygen-tips) / [Resources](https://blog.oxygo.life/tag/resources) / [Health](https://blog.oxygo.life/tag/health) / [Oxygen](https://blog.oxygo.life/tag/oxygen) [Previous Post](https://blog.oxygo.life/the-oxygo-portable-oxygen-concentrator) [Next Post](https://blog.oxygo.life/oxygen-safety) ### LATEST NEWS ![](https://blog.oxygo.life/hs-fs/hubfs/How%20to%20Get%20Started%20with%20Medical%20Oxygen%20Your%20Guide%20to%20OxyGo%20Products%20V2.png?width=767&name=How%20to%20Get%20Started%20with%20Medical%20Oxygen%20Your%20Guide%20to%20OxyGo%20Products%20V2.png) [How to Get Started with Medical Oxygen: Your Guide to OxyGo Products](https://blog.oxygo.life/get-started-with-medical-oxygen) ![An older couple walking at night through a snow covered lit up city.](https://blog.oxygo.life/hs-fs/hubfs/COPD%20in%20the%20cold%20(2).png?width=767&name=COPD%20in%20the%20cold%20(2).png) [Managing COPD Symptoms in Colder Weather](https://blog.oxygo.life/managing-copd-symptoms-in-colder-weather) ![A model heart in a doctors hands](https://blog.oxygo.life/hs-fs/hubfs/copd%20and%20its%20impact%20on%20cardiovascular%20system.png?width=767&name=copd%20and%20its%20impact%20on%20cardiovascular%20system.png) [Understanding COPD and Its Impact on the Cardiovascular System](https://blog.oxygo.life/understanding-copd-and-its-impact-on-the-cardiovascular-system) ### Categories -

I used tanks for almost a year before finding out about OxyGo. The tanks were a lot of work and I often found them exhausting to use and set up … OxyGo gave me my life back. Now I want to go places. I can take OxyGo to the pool, beach, grocery store, shopping. I am often gone 8-10 hours a day." ~ Cathy W. | Sandusky, OH "OxyGo has given my mom her life back and mine too. Freedom to be the type of person she was before. The extra double battery is even more amazing. Before OxyGo she could not go to Columbus, two hours away to see my sister. Now she can see her grandkids—It’s a product that has definitely made her life a lot happier." ~ Angela W. | Sandusky, OH "I have patients coming in to switch out for the OxyGo POC because of its battery life. And they love and feel safer with the OxyGo POC because it shows exactly how much time is left to the minute rather than showing remaining time in percentages, which is what units competitive to OxyGo POCs do. Expressing remaining oxygen supply in exact minutes left is a big comfort advantage OxyGo has with patients." ~ Ruben L. | Wickenburg, AZ "My life with OxyGo is really 103% better than it ever was with a medical oxygen tank!" ~ Rodger R. | Colorado Springs, CO "When I found out that I needed oxygen, I thought many activities were lost to me. OxyGo has restored my confidence in getting where I want to be, and my enjoyment in doing what I love." ~ Karen A. | Cleveland, OH [Share Your Story!](https://oxygo.life/contact-us/) - [Home](https://oxygo.life/) - [Get OxyGo](https://oxygo.life/oxygo-family/get-oxygo-today/) - [Privacy](https://oxygo.life/privacy-policy/) [866-234-1692](tel:866-234-1692) [![Facebook](https://blog.oxygo.life/hubfs/OxyGo_January2020%20Theme/Images/facebook.png)](https://www.facebook.com/OxyGo.life/) [![Youtube](https://blog.oxygo.life/hubfs/OxyGo_January2020%20Theme/Images/youtube.png)](https://www.youtube.com/channel/UCDDhnuSdGMW0S39K1Lu_BPA) [![Instagram](https://blog.oxygo.life/hubfs/OxyGo_January2020%20Theme/Images/instagram.png)](https://www.instagram.com/oxygopoc/) ![Keep Going](https://blog.oxygo.life/hubfs/OxyGo_January2020%20Theme/Images/keep-going.png) © 2022 OxyGo HQ Florida, LLC.
