Tale of Two Masks: The Good and the Bad
        Attached are two charts. One good (Dreamwear nasal mask) and one bad (Dreamwear full face mask).

I never seem to get a great result with the FFM (usually 5 to 10 AHI). I always get a good result with the nasal mask, but can't always wear it due to idiopathic rhinitis. 

I'm pretty new to this. Should I seek a new kind of FFM for the nights I need to wear one? I tried to Amara View during "tryouts" with my DME but thought the other one was much more comfortable. But if it doesn't work...no use sticking with the Dreamwear FFM.

A full face mask has more volume and the CPAP may be less responsive in addressing apnea than with nasal therapy, however this is pretty extreme. I normally would suggest increasing pressure up to 2-cm for a FFM. In this case, that might solve the problem. The median pressure with the FFM was 11.42 and the pressure was at the maximum a significant part of the night. With nasal therapy the median was 9.24 and with the 95% pressure hitting 12 cm several times, I think even here, a little more room may be in order. I think your limitation on pressure at 12 caused this problem, and would change it to 14 or more with the FFM.

By chance were you wearing a cervical collar with the nasal mask and not with the FFM?

I think Sleeprider has a good point about the differences between the two.

Saw you did change mask type according to chart.

I'm not a doctor in real or fictional life. My posts include opinions based upon user experience regarding CPAP therapy and should not be considered medically professional direction or advice. Even a 1,000 mile trip requires a good first step. My recommended first steps include getting good walking shoes, 1 great cup of coffee, and a good GPS.

Thanks for the advice. I haven't messed with the doctor's prescription as yet but she based it on the early successes with the nasal mask, so the adjustment makes sense.

Have not tried one! Maybe it would help with the FFM.

Yes, as noted, I like the nasal much better and also have had much better therapy. But need a better FFM mask for times my nasal congestion is untreatable.

Hello all, 

        Here is another Nasal Cushion vs Full Face Mask pair.

As you can see, last night with the FFM was "leak-o-rama" and I need to figure out how to get that FFM to fit better. Or try another.

Wondering if the leaks correlate with poor control of OA?

Still working on getting nasal congestion under control. Am taking Allegra daily; threw away full bottle of Flonase and trying Nasonex instead, hoping one steroid formulation may be better than another. When I take Afrin, my nose clears up COMPLETELY but as well all know, taking Afrin daily is a big no-no.

Thanks for any comments.

If you experience high leakage then the machine cannot effectively deliver pressure to overcome OA. So yes.

Also, during high leakage the machine may not record OA. So realistically, the numbers may be inaccurate in Sleepyhead

Thanks JesseLee. I will do what I can to get the leaks  under control, or as noted, see if I can get a new FFM to try. 

As you can see on the chart, I did take Sleepriders advice and increased by 2 my upper auto range limit to 14. Tonight my nose is clear enough to return to the nasal cushion. 

I'm also trying a cervical collar tonight to see if that will make a positive difference with that mask, which on a good night for me gets AHI to around 2. I think my pillow has been a bit too high and possibly creating a bit of a chin tuck, so will play with the collar and a flatter pillow and see what happens. 

There are days I realize I am messing with too many variables to draw valid conclusions!

THANKS again.
