How often should oxygen nasal cannulas be changed? Update: Our supplier recommended we change the cannulas monthly and the tubing every 60-90 days. My father has friends who's suppliers have had different guidelines.
How often you need to change your pad depends on how heavy your flow is and what type of pad you are using. Pads come in all different absorbencies, so match up the pad absorbency with your flow. On your heavier days, you may need a more absorbent pad and on our lighter flow days a less absorbent one will do. No matter how heavy your flow is though, you should change your pad at least every 3 or 4 hours so you donât end up with an odor from bacteria that can grow in the blood. Yuck! As often as you need to. The truth is, the length of time you can wear a pad really depends on how heavy your flow is.
