leak advice
#1
I've been using cpap for roughly 6 months now. The last couple of weeks I've been getting high leak rates, and unsure why or how to stop them. This also results in my eyes and sinuses being filled with air, feeling worse than if I hadn't used the machine and me struggling to stay positive about this whole experience.

Previously my avg leak was around 12-14L/min. And fairly flat throughout the night.

I've been having instances roughly 1hour apart and lasting 30mins give or take with max leak rate.

Mask is clean, I'm freshly shaved before bed, all equipment is new and has worked fine with weeks of no issues, no changes in settings or pressures...
Any ideas of what could be causing it or how to rectify it?

An F10 should not leak so much at 9cm fixed. I am assuming that it was working fine for 5+ months.

Things to evaluate/try:
1) How old is the mask cushion? The silicone may start breaking down.
2) have you Adjusted your straps' tension lately. They may stretch over time and your goldilocks setting may have moved due to this.
3) when the machine starts, do you lift off the mask a little bit from the face to let the silicone seal to inflate?
4) are you tightening it too much? In my experience with F10, I would tighten the top 2 straps snug and the bottom 2 were left much loose.
5) Have you tried mask liners? In my experience, they made the whole Process much manageable. They eliminated the need to shave before masking up too.
Started APAP 4-20, Closed range to 7.5-14, then straight 8.0 w/ Aflex 3
RDI always below 1. But sleep much much better at straight pressure.
Started on F10, Tried Quattro Air successfully. Finally settled on P10.

mask is 8 weeks old

Headgear is also only 8 weeks old, have reset it a couple of times.

Yep
4) are you tightening it too much? In my experience with F10, I would tighten the top 2 straps snug and the bottom 2 were left much loose.
Describes how I set it up very closely.

Never tried them, will do some research... Any brand in particular work for you?

I would tighten the top 2 straps such that the top part of the mask cushion would be tight at the bridge of the nose(when the cushion inflates). But the bottom 2 straps were loose enough that I could grind my teeth without any issues.

I used to cut mask liners out of an old worn out tshirt. You can google 'DIY mask liner'. Somebody has a template online that I used to cut Mine.

Interesting

First big leak is between 2.5 and 3hours from when I'm asleep. from the 13L/min up to 100+
I either have no more for the night, or a re-ocurance every 45mins.

I wonder if I'm simply rolling over or if it's my body temp dropping and I'm getting restless?

That is what I was thinking. You are just rolling over and nudging it loose.

Why am I rolling and how do I teach myself not to do it in my sleep?

As mysteriously as it started its stopped... The only thing I can put it down to was it ran through a cold snap and I wasnt warm enough overnight.

I'm going to try that mask liner trick too.
I have had pretty good luck with Elmer's & Avery glue sticks to keep the surface tacky.
It's a bit ornery working with those but after few minutes they stick.
There are also Skin-Tac wipes you can get that put down a coating of rosen Those work too but they
are pricey and the stuff gets on your fingers making them sticky.
===>
The whole night is showing up zero leaks!
This is good.
