Im 24/7, but was told this when I was just on nighttime O2. I do notice around 2 weeks or so my cannula getting stiffer and I change it at that time. They are a non chargeable to ins so my company gives me several at a time. Not sure what other companies tell their clients.
The guy that comes from the company is funny, a real nice guy, and our Marmalade likes to sneak in a chew on my clear tubing , sometimes the green too, and so he told us that cats are definitely a big reason people change their tubing often.

I am on nighttime O2 and change my cannula every 3 weeks. I was told I could go 3 to 4

@A myPHteam Member. Are you just nighttime use? I was told 3 to 4 weeks for the cannula and clear but 3 months for the green. I would imagine if you use O2 more often than just nightly it would require more changes.

The clear tubing with cannula should be about every two weeks, and the green tubing about every four weeks. I use my clear tubing about that length of time, sometimes a little more or sometimes a little less, it depends on how they feel. When there's a little stiffness it definitely needs to be changed even if its not yet time, it feels so much better to have fresh.

Adding humidification to oxygen therapy can help reduce nasal discomfort, though it's important to maintain proper sanitation since adding water increases contamination risk. Many myPHteam members have found humidifiers beneficial for managing nasal symptoms. To help manage nasal comfort while using oxygen therapy, consider these tips:

- Use water-based or oil-in-water creams (avoid petroleum jelly)
- Try saline sprays or gels
- Ask your doctor about nasal cannula padding options
- Avoid nasal decongestant sprays as they can damage nasal passages

For specific guidance on how often to change your cannula, please consult with your healthcare provider, as they can provide personalized recommendations based on your usage patterns and medical needs.
