Your provider will give you more cannulas so you always have at least one spare, and usually they'll give you a bunch.

🤣🤣🤣🤣

got me again cujojo lol i still dont know what you are talking about but i wanted to thank you for trying

My oxygen company sends me new cannulas when I need them. They mail them to me. I get them in a few days. Good luck. Have a blessed Sunday.

This is unbelievable. I sent that without putting anything in it. I guess its supposed to already know what I'm going to say!!!? I have seen those advertised on TV. It's a slick little gadget!!
