yes when you take it off before you put it back on check to make sure it is not twisted and there is more then one way to wear it :) try other ways :)

My husband suggests unrolling it like a water hose before connecting the cannula.

Well I just called my oxygen supplier. We're going to try another type of nasal cannula. Presently I'm using soft cannula.

Seems to be an issue with the soft hoses

That happens to me all the time, as I walk around the house it tightens up. No answer to the problem that I know of. Mine also turns into a snake that wraps around my legs lol
