Leak Rate Bad/Not? Can't get my AHI to >5

I've been on therapy for almost 10days nows. I only had my AHI less than 5 i guess once..

I'm not quite sure if the mask is leaking or not.. I sleep sideways when i'm still awake.. but lie on my back when sleeping..

my question was if i have a leak rate as before my setting was only 7 cm/h20 - 16, to make it on the safe side.

yet now most of the time it blows to 14-16 in the morning.

here's my stats today:

Channel Min Med 95% Max

W-Avg: 12.16 7.60 12.66 14.20 15.60

W-Avg: 10.16 5.60 10.66 12.20 13.60

Minute (L/min)
W-Avg: 7.32 0.00 6.12 14.50 29.25

Resp. Rate
W-Avg: 14.11 0.00 13.60 19.80 50.00

Leak rate Min Med 95% Max
0.00 3.60 12.00 26.40

Pls. let me know.. Thanks a lot!

Your leak rate looks fine.

I'm thinking there is too great a distance between your min pressure and your therapeutic 90% pressure. So what happens is the machine dials it down when you're on your side, then you roll over and the obstructives go a little crazy go nutz.

If it were my cute little body I believe I would set the minimum up a bit. Say to 9 or 10, and watch the results.
