Pressure Setting - Full Face vs. Nasal

[do57672]

Should the pressure setting be the same when using a full face mask vs. a nasal mask? I've tried both, my wife says I snore with the FFM and not with the nasal mask. I can use either one but I can't seem to stop mouth breathing with nasal mask & don't want to snore when using the full face. Maybe I should just use the FFM and bump up the pressure to try & knock out some snoring?
Any thoughts?

The official answer is that there shouldn't be a pressure difference, but in actuality some people do require more pressure with a full face mask. It's because the same pressure is being diverted through 2 airways instead of just one. I can use 14 cm with my nasal mask, but I need 16 with my full face mask.

Thanks Randy. I must be in the same boat because it's doesn't make sense to me to be snoring on one and not the other. I think I'll try turning up the pressure and using the FFM

Why depend on your wife for information on the effectiveness of your therapy? Next time she might sleep through your snoring.

Download the software and see what is really happening with each mask - http://www.resmed.com/int/assets/html/s ... ister.html

If the data shows snoring I would bump the pressure up one cm each night until it goes away. Look at the "daily detail" data every time you make a change.

Once you get the setting stable you can try taking the pressure down 0.5 cm per night to fine tune for an optimal pressure.

Make sure to keep an eye on the leak line in addition to the events. Also think about how you feel the next day.

Good luck,

I appreciate the link. I had the sleepyhead software & now the Resscan (which I never could find, so thanks again) I know it sounds crazy but until yesterday, when she mentioned the snoring, I never really paid attention to the snore graph, just the ahi & leaks. The snore line is definitely higher & more active when I'm using the FFM. I'll try bumping up the pressure 1 tonight & see what happens. - Is that normal for the results to be different on different mask if the pressure if the same when wearing each? From what I can by reading other threads it picks up on vibrations so maybe mouth breathing is louder, I don't know just a thought.
I'll let you know my results.
Thanks again.

We all have different anatomies so who would know about these differences? It could take a lot of difficult investigation to determine for sure.

Intermittent mask leaks causing vibrations (Less refined members call them mask "farts".) can be picked up in the data as snores.

Even in the sleep lab with more advanced equipment and a technician watching and listening, optimal titration is simply tweaking the settings until data and the subject's appearance and sounds are satisfactory. Something similar can be said for tweaking at home: Experiment for some number of nights to find settings which produce good looking data, a subjective feeling that you slept well, and a good energy level the next day (and maybe a good report from your bed partner).

During the at-home self-tweaking stage you may be looking at data every day for some period of time. At some point you will settle in on some settings and look at the data maybe once per week or less. At least that is the way it worked for me.

Thanks again. I'm definitely in the stage where I check the data daily, lol. I wake up each morning and the first thing I do is download my data from the night before, and then study it. I figure like anything new it will probably wear off and I'll just check it once a week or so.
