If the cuff no longer works on your ET tube - cut if off! I know that sounds drastic but it will stop other staff members from trying to inflate it!
I find often that the stoppers on the cuff come undone, so after you have inflated it - use the cover of a needle to place over and that ensure it stays done!

I've found cutting the et tube cuff off renders the et tube useless. If the cuff doesn't work, discard the tube and buy a new one
