I have a ResMed S8 Elite Machine and don't know what mask setting I need to use.
The new mask has a value of X1 but the machine doesn't give me choices by value.
The choices on the ResMed machine are:
Ultra, Standard, Mirage, Swift, Activa
I tried it on Ultra which is my old mask setting, but I woke up feeling awful so I know that's not right!
So does anybody know which setting would work?
