Am I mouth breathing?

[DreamerFred]

Hi,
New to CPAP for a week and the Board.
I am using a Phillips Dream Station 2 and they Dream Mapper App.
I have a nasal pillow.
My question is if I have 0 leaks on the app does this mean I am not mouth breathing. Before starting CPAP I was a loud snorer and assumed when snoring I was mouth breathing. Now my partner says no snoring at all. In addition I not longer have dry mouth when sleeping. So I assume the mouth breathing is gone. The technician who helped me buy the set up says this all indicates I do not have mouth breathing.
Does any one have any thoughts or advice.

Thanks. F

I don't know about DreamMapper, but if you could download the OSCAR software,
we could take a look at your leak rate graph.

If you're not waking with dry mouth, and Dream Mapper says 0 leaks, then there's a good chance you're doing ok. But, it's still best to look at the leak graph in OSCAR.
