CPAP Blows My Mask Off After Awhile - dmorgen - 05-17-2020
[attachment=22969]
This is my first time posting here. I was diagnosed with sleep apnea probably 6-10 years ago. I then started using a ResMed AirSense 10 AutoSet CPAP machine, which I'm still using. I've used different masks, currently the QuattroAir Airfit F10. The last couple of years have been a disaster from the consistent use of CPAP point of view. Whenever I go to sleep with the CPAP, everything is ok for 1-3 hours. Then I feel like I'm in a wind tunnel. The CPAP is blowing so much high pressure air that the mask won't stay seated. I've tried the supposedly correct way of using it, getting the cushion full of air then keeping the mask just tight enough, I've tried tightening the mask very tight as I've been told by the CPAP folks. Nothing helps. I've had my sleep person & the CPAP person show me the "right" way; but I'm not going to sleep then so they never get to see the problem. I've had the CPAP machine serviced. I had a sleep study within the last year or so; they said my CPAP was working right, correct pressure, etc. But they tried different equipment on me & I didn't sleep very much that night because of the environment. So I doubt I used the CPAP long enough for it to misbehave. Now I'm just not using the CPAP most nights which would awaken me without solving the problem & getting very little sleep; I feel much more rested when skipping the CPAP than using it.
So I'm hoping this board will help me solve the problem. I'm attaching a screenshot from Oscar.
Any ideas! Thanks for your help!

If the head strap harness is too tight, when you roll over maybe or as you drift off to sleep laying on your side, you put pressure on the silicone seal portion of the mask and it shifts, as so if it's to loose. Your Amara mask doesn't fit around the bridge of your nose and isn't supported as much as a fuller face mask. So the noise might be air escaping between the mask ad your face. From time to time my P30i shifts sometimes, as I described how yours does. But with me my Central Apneas, I believe, wake me.. so I shift around more, for now.... hopefully soon.. I'll sleep better. That's my take....

You need to change masks. You are apparently using ramp from a minimum pressure of 4.0 for 15 minutes, and every time your machine hits 6-7 cm pressure your leaks are out of control. This is simply a mask that does not fit and will never work. We have seen masks not get "blown-off" up to the maximum pressure the machine will generate. Quit fighting the mask, and get one that works or turn off ramp so you get the right fit before starting. A pressure range of 8 to 12 cm is not very high. If you have never tried nasal therapy, give the Resmed Airfit P10 a try. Tiny mask with no noise, and as long as you don't leak from the mouth, it's very quiet and comfortable. If you don't make a change in masks, this attempt at therapy will en like the last. Your problem is not CPAP it's the mask.

Welcome to the forum.
Let's try some new settings.
Ramp off
Min pressure = 6
EPR = 2
Max pressure = 10 for now.
Try for 1 night then repost

Thanks for the suggestion. Tomorrow I should have some time to figure out how to change these settings & will try the cpap tomorrow night. I'll get back to you with the results.

This mask is much more finicky (even when it's working) than my previous mask. So I wouldn't be surprised if you're right about it being the wrong mask. The mask you suggest looks great ... so minimal compared to what I've been using. Unfortunately, I'm a mouth breather, so it won't work for me. BTW, I have both central & obstructive sleep apnea. I have an extra length of hose inserted in my tubing to deal with the central. Any other mask you'd recommend. My first mask was an Amara View. It worked well for awhile, at least from my perspective. But after awhile, my sleep doc didn't agree after reviewing the detailed graphs of my breathing. Things have been going downhill ever since!

Tell me about your EERS setup, and how you started using it. This is an important part of what you are doing and may impact the advice we would give. A picture of your setup would help a bit with that. I assume you mean e one 6 inch length of coraflex tubing inserted.

You could use a chine strap and not have to be a mouth breather. I haven't crossed that road for face mask. It's hard to recommend a mask... fit is important, which is comfort, but function is important too. When I went to pick up my machine, the girl asked me face mask or nasal pillow? I said I ain't wearing no face mask. Sad part is they only give you one or the other and then within the first 30 days, you can switch out and keep the first set up. But the nasal set up didn't bother me until after the 30 days. I changed the pillow to a different one, and then just learned how to fine tune the tension on the harness. It would have been nice to have both due to congestion. Insurance companies are not that generous.
In September I'll get a nasal mask so i can switch out from pillow to mask. But I have to wait till another 6 months to get a face mask.

From what I gather on the write up, it's basically a safety feature in case the machine quits and allows you to continue to breathe through the safety valve. Unless it has benefits I'm unaware of?
"prevent the side effect of central apnea" it says.... and "EERS creates a larger dead-space by moving the mask vent to a position further down the tubing toward the xPAP machine." Does this set up enhance the performance of Bilevel machines?
