Can Oscar show if someone is mouth breathing with nasal pillows

[sndraco]

Hi 

My father in law who is 85, was diagnosed with sleep apnea (moderate) last year and is using a BiPaP machine. Initially, he tried the F20 mask but found the magnetic straps and buttons difficult to manage ie to put the mask on each day. So he is now using the P10 nasal pillow mask which is much easier for him to get on / off. 

However, I don't know if he mouth breathes a lot or not, and wondering if Oscar data can show that. And also is there a level of mouth breathing that is ok even with nasal pillows?

Asking as he lives in a different location, and doesn't want someone to watch him while he sleeps, so I can't watch him while he sleeps to see if there is significant mouth breathing or not. 

Thanks

I have set up Oscar on his computer and so can download data and analyze it for him.

Yes, but you need to analyze the leak chart and the flow rate chart.

Is mouth breathing ok. Sometimes. Expiratory mouth breathing is ok period because our therapy occurs 0n inhale. Large leaks are ok, not preferred, if you are just over the limit and your AHI is consistently low. If you are seeing UA events your device is having trouble seeing what is going on and you have exceeded your devices capability of making up the difference.
