I’m currently using Invisalign and have mild mandibular retrusion/overjet. My orthodontist told me that the longer treatment option they originally offered would have included mandibular advancement with Invisalign, but I’m not currently using the Precision Wings for that.

I also have mild OSA/sleep-disordered breathing and still have a lot of flow limitation on PAP. Has anyone tried Invisalign mandibular advancement, and did it help your breathing, sleep, or PAP needs? Does anyone think this would help? I know Invisalign mainly helps with bite and teeth, but it does say mandibular advancement in the name.

I know it’s not guaranteed to treat OSA/UARS, but I’m wondering if it could help since my lower jaw is somewhat recessed.

I did the Cottle Maneuver it did something, I did use afrin though for two nights as an experiment, one night with cpap, and one without, no difference in how I felt or therapy.

So could it be the cause of my problems or no?

My ENT never diagnosed me with it last year, only nasal obstruction. Kinda weird.

I’m considering getting an AirSense 10 that has already been AirBroken to enable bilevel modes, and I wanted to understand the potential downsides before deciding between that and a factory AirCurve.

Mainly wondering:

1. Is there any additional risk or reliability concern with buying a machine that someone else has already AirBroken versus doing it yourself?
2. Once it has been properly AirBroken, can it basically be used normally, or would I need to know how to work with the firmware/coding myself for updates, troubleshooting, etc.?
3. Are there any meaningful differences in functionality or reliability between an AirBroken AirSense 10 running VAuto and a factory AirCurve 10 VAuto?
4. Anything else I should check or know before buying an already-modified machine?

I’m not very experienced with firmware/coding, although I can learn if necessary. Just trying to understand what I’d be getting into before choosing between the two.

I’m trying to understand something about my PAP data.

My titration study recommended around 12–15 cmH₂O, but I’ve had nights using a nasal mask at around 7 cmH₂O where my machine still reported an AHI below 1 and the obvious apneas/hypopneas seemed controlled. I did not feel a difference in symptoms however.

At the lower pressure I still have a lot of flow limitation and don’t feel better, but why would such a low pressure appear to control the scored obstruction if my titration needed much higher pressures?

Could the titration pressure have been driven more by REM/supine sleep, flow limitation/RERAs, or something else that isn’t reflected well by the machine-reported AHI?

I’m currently using an AirTouch N30i with APAP/EPR, but at higher pressures I keep getting significant mouth leaks. Even with double mouth tape and a chin strap, I always wake up the mask off. Other times the tape is still on but the mask is off, or both are off. It seems like the mouth leak is making it hard for me to keep therapy on throughout the night, and I end up removing things unconsciously.

I can tolerate a full-face mask around 9–11 cmH₂O, but at higher pressures I have to tighten it so much to control leaks that I get pretty bad pain in the back of my head.

Would it make more sense to use the full-face mask at 9–11 so that if my mouth opens I can still keep PAP on all night, even if the lower pressure doesn't treat my residual flow limitation as well? Or would that defeat the purpose and I should keep trying to make the nasal mask work at higher pressures?

Has anyone dealt with something similar?

Flow limitation in general in breathing, like what anatomical/ breathing features or attributes.

Really curious what would be restricting breathing just not enough to be a total collapse.

Yes, the nervous system helps us with our oxygen drops in some way? I guess?
but is it a positive feedback loop where the relatively poor sleep quality prevents nervous system rest leaving it hyperactive during the day, which leaves it hyperactive during night and bam slight air restriction, microarousal?

What do I even do ?

Hi all! I ran several nights through the Glasgow Index and one representative night through AirwayLab. Would anyone be willing to take a look and tell me what stands out, especially regarding flow limitation/RERAs and what you’d try to optimize it (settings, different machine, wedge pillow, etc.)?

I’m on CPAP/APAP, not BiPAP. AirwayLab seems to have interpreted some of my settings as analogous to those of BiPap Or calculated them using the flow rate.

Thanks so much!

Will a BiPap even help with this?
Vcom did nothing unfortunately, I couldn't tolerate it.

I can still hear with the cpap on but hopefully you know what I mean.

I use an airsense 11, airtouch n30i.
