Can't seem to find exactly the right help in previous threads so can someone please help me with numbers?
Recent user, first 12 days fantastic and index came way down.
Every night since, I have woken up with a "bruise" on the bridge of my nose and have watery eyes. Sleep clinic checked mask and said it was the right size and wasn't too tight, so I've been putting a small piece of soft cloth under the bridge of the mask. Now I have more leaks.
However it's the numbers that confuse me: Last 3 nights are:
AI 2 Hy 1.3 AHI 3.3
AI 2.2 Hy 1.7 AHI 3.9
AI 1.7 Hy 0.4 AHI 2.1
BUT...over a 30 minute period last night I had 9 Obstructive, 1 Central and 6 Hypopnea events from 10 to 35 seconds, so how can the AHI be 3.3? The night before it was 11 events from 10 to 29 seconds and 7 hypopneas.
Hope to get some help?

AHI is average number of events per hour, you might have some events in some period (such as sleeping on your back, or/and during REM) and none in other periods. Below 5 is normal on PAP
As for mask bruises, try not over-tighten the straps, Resmed nose pads, Remzzz liners, pad a cheeks liners, also don,t hesitate ask your DME to trial a different mask
The AHI goes by the number of events, not how long they lasted. That's where watching your data comes in handy.
With that many events in such a short time period, my guess would be you rolled over onto your back. As long as the leak rate was within normal ranges, you were either on your back or your neck was at an angle or something similar to help cause the obstruction.
The Quattro is a full face mask, right? Instead of putting it just under the part that is sore, cut out some cloth the fit under the entire seal. Something very thin like an old tshirt. There's products out there (zonk mentions them) that work, too, but until you get some, you can try this. But putting the cloth under just that part, you aren't getting a good, solid seal.
