First 2 nights

[PeaceLoveAndPizza]

Sleep breathing is very different than awake breathing. It looks to me like you were tossing and turning, or just settling down. Nothing strange there.

tried 10 again. nice and stable until the morning. really only issue is my neck, not easy to find a comfortable position without leaks! never could get used to memory foam pillows before cpap but i'm thinking of trying again.

no reason to change anything i take it? the extra pressure really isn't bothering me at this point.

[Narcil]

some more data. i'm just going to keep increasing min pressure to 11 or maybe even 12. then i think i'll try cpap mode just to see what happens.

i'm trying to adjust the mask almost every night but nothing i do seems to fix it 100% but i don't think it's a big problem. always wake up at some point with the mask slightly lifted up and air leaking into my eyes or w/e. think i'll order the n30..

[Narcil]

Anything you would change? 

Are the leaks causing the variable breathing rate? or is REM sleep causing the variations in breathing rate?

Thanks!

This looks like a bit of mouth breathing actually doesn't it? sad i love this mask but it seems to happen every night. maybe i will try this chin strap..

Good observation Narcil.  A longer, more rounded top leak (or the top could even be flat) usually points to a longer term mouth leak.  

A short spike is usually a mask leak (from a postion change, etc.).

[Narcil]

finally got used to the chin strap but it makes no difference.. not sure if it's because i'm not using it right or maybe it wasn't mouth breathing at all? feels pretty tight anyways, and definitely need some effort to open my mouth. i never have a dry mouth and when i wake up it's because of mask leaks (mostly air in my eyes) so idk! maybe it's small enough to not worry about but FLs always seem to go up during the leaks.

do people usually put the chinstrap under or over the mask? under seems to work better with the n20 with all the plastic holding the mask.

When I used a chin strap (I don't anymore), I used it under my mask.  I guess you could use it over the mask also.  The key for me with a chin strap was finding one that pulled my lower jaw straight upwards (and not backwards).  Backwards means it can contribute to a blocked airway.  Straight up or even slightly forward can push the lower jaw forward slightly and possibly decrease airway blockage.  

There are many different designs of chinstraps also.  I also cut and modified mine for both increased comfort and performance.

[Narcil]

it's certainly not making it worse so i don't think it's pulling my jaw back.

mine looks like this and i make sure the big strap is as vertical as possible.



so you still think it looks like mouth breathing or?

Your 1st chart looks like it has some mouth leaks.  Mouth leaks go up from the zero line and stay up awhile (either a round top or even a flat top to them).  The 2nd chart looks like mask leaks.  Mask leaks are spikes upward and then back down.
