What mask did you switch to that improved your numbers?

I use the UMFF at 12. Had a 0.0 AHI.....night of Apr. 30. Average for the month of April it was 0.5.

If it's sized and adjusted properly, it's a good mask.

Is your machine set for the right mask?
From what I've read here, the ResMed machines tend to score a little higher on hypopneas. AND, a little extra pressure can bring them down.

Wulfman....the UMFF is a great mask...best I have ever had. I did not mean to imply otherwise. My machine is set correctly to the mirage full face mask. I am envious of your low numbers.

Track,

Do you have problems with GERD?

What fixed pressure seems to give you your best "numbers"?

Did you use EPR?

Den

I do not know if I have GERD.....but I am careful to make sure I eat at least 4 hours before going to bed at night....to avoid stomach issues. I have no problems during the day.

These are my numbers the last two times at 15 CPAP.....Leaks at L/s
1. Leak....30 AHI....4.8 AI.... .8 HI...4.1
2 Leak.....20 AHI...7.0 AI...2.0..HI...5.

Last time 2 times at 13 cpap
1. Leak.....22 AHI....5.0....AI...1.1 HI...3.9
2. Leak...44 AHI...4.2 AI... .7 HI...3.5

Last time at 14 CPAP
1. Leak....52....AHI....6.1 AI....1.0 HI...5.1

Last time at 12 cpap
1. Leak.... .2 AHI.....4.4 AI....1.0...HI...3.4

here are some numbers for apap from 9-13
1. Leak... .28, .42, .38 .16, .44
2.AHI..... 5.9, 3.4, 7.1, 4.4, 6.5

Here are some numbers from 10-14
1. Leak..... .30, .34, .26, .24
2.AHI..... 5.0, 4.5 4.7, 7.7

Here are some numbers from 12-15
1.Leak..... .30, .18, .56
2.AHI.... 5.6, 6.3 4.4

Would you be willing to try a straight pressure of 10 or 11 for a few nights?
If you use EPR, you might stick with either a setting of 1 or 2.

It seems that your numbers get somewhat worse as the pressure goes up.

The lowest fixed pressure you listed was 12......so I'm just wondering......

Den

Heck yes...I will try it. I will set tonights at 10...that will seem heavenly compared to 15.

I tried it for 3 nights at 10-11. Won't do that experiment again. It was scary reading the events chart and the number of extended AI. The last 3 nights I have settled on 13-17 with my 95% pressure being in the 13s. I have also had my best numbers at that pressure. AHI at 4 with AI from .3 to 1.0.
