I have a hard time adjusting to FFM. If I were to go back to the nasal pillows, will on sleepy head program show that I open my mouth to breath.

Your machine will flag any leaks...no matter where they come from but it can't tell if it is mouth leak or mask leak but it's usually pretty easy to spot on the Sleepyhead reports if it is a problem.

So while we can't tell where the leak is actually from...it's fairly easy to spot mouth breathing leaks once we see them a few times...they are usually prolonged and have a raised plateau appearance on the leak graph.

If you go here and scroll down to where is shows an example of a probable mouth breathing leak you can see what I am talking about.

While it is a ResScan example it shows up the same way on the SleepyHead leak graphs...can't miss it.
