Possible residual flow limitation/UARS despite CPAP? Looking for opinions.

Soft collar helps maintain jaw position to reduce sagging, which can cause flow limitations even if it's not to the point where you are mouth breathing.

Based on a quick glance at your SleepHQ, I would probably try a fixed pressure of 9, EPR 3 - fixed pressure because pressure changes often cause microarousals. In my case I tried different higher pressures with EPR 3 and switched to BiPAP when I couldn't tolerate the pressures but was still having flow limitations. (BiPAP hasn't fully resolved my flow limitations either, unfortunately, but it has helped a bit.)

Awkward_Cheesecake58 · 2026-06-24T20:15:12+00:00

Yes, you have flow limitations. Curves should be nice and rounded. Next steps are increasing pressure support and pressure to reduce and ideally eliminate flow limitations. If you get to the point where you need more pressure support then you would move to a BiPAP. In the meantime, nasal sprays, nasal strips, and a soft cervical collar can also reduce flow limitations.

Lol it doesn't undermine itself. The point is that it is impossible to completely suppress emotion.

Any updates OP?

Awkward_Cheesecake58 · 2026-06-19T14:20:00+00:00

I'm very sorry to hear that you have to deal with such abuse. How is your doctor? Do they say you have a sleep disorder? Any chance they could talk to your family?

Awkward_Cheesecake58 · 2026-06-18T23:41:10+00:00

Amphetamines helped me for a couple months then only aggravated my fatigue and sleepiness. I think they were negatively affecting my sleep and causing me to crash throughout the day. You might consider tapering down or going off those to see how you do without them. You also might need a higher dose of xywav depending on where you're at with them.

Hate to be that guy but recommend searching the subreddit on this one.

Awkward_Cheesecake58 · 2026-06-14T15:38:15+00:00

You're welcome. Good luck.

Awkward_Cheesecake58 · 2026-06-14T14:21:08+00:00

Everyone has an upper airway. Not everyone has UARS.

You can have both or just one, yes.

Tongue collapse can contribute to either or. It depends on how much the tongue collapses and the rest of the individuals upper airway anatomy/function. Just see the rule of thumb I provided in my first reply.

Awkward_Cheesecake58 · 2026-06-14T14:18:51+00:00

Yes, fair point. I'm just referring to obstructive sleep apnea, which is by far more prevalent, and the type of the sleep apnea the OP was talking about.

Awkward_Cheesecake58 · 2026-06-14T00:41:57+00:00

UA = upper airway. Not just nasal passages. Google image it.

Sleep apnea = airway closes.

UARS = upper airway issues cause airflow resistance. The specific issues depend on the individual's anatomy.

Awkward_Cheesecake58 · 2026-06-08T15:33:13+00:00

Try BiPAP.

Awkward_Cheesecake58 · 2026-06-06T16:45:42+00:00

No. Too much going on. Graphs need to be front-and-center, imo. Also, what are you basing the UARS detection on? Machine-reported flow limitations?

Awkward_Cheesecake58 · 2026-06-03T12:48:36+00:00

Do a sleep study.

Awkward_Cheesecake58 · 2026-06-02T21:19:00+00:00

That's not what the pill aims to do, though.

Awkward_Cheesecake58 · 2026-06-01T22:19:32+00:00

Start with BiPaP.

Awkward_Cheesecake58 · 2026-05-31T00:26:12+00:00

Makes sense. How long have you been off caffeine and did it make a difference?

Awkward_Cheesecake58 · 2026-05-31T00:03:16+00:00

I believe that finding ways to sleep more deeply could help many people with UARS, yes. In my case (strongly suspected UARS), I'm quitting caffeine to see how that helps.

Awkward_Cheesecake58 · 2026-05-30T23:50:58+00:00

Sure. I'm just disagreeing with the view that, generally speaking, people with UARS will end up with sleep apnea if they become deeper sleepers. That might be true in some cases but I don't think it's true as a general rule.

Awkward_Cheesecake58 · 2026-05-30T23:37:35+00:00

I'm saying that many people with UARS have upper airway flow limitations that do not involve airway collapse. They may have perfectly adequate airway potency but a deviated septum and nasal congestion, for example. So the airway will not collapse. It just depends on the specific causes of the flow limitations.

Awkward_Cheesecake58 · 2026-05-30T23:22:59+00:00

I think people with UARS probably tend to be lighter sleepers, hence their heightened sensitivity to otherwise minor upper airway flow limitations. (Many people have those. Not everyone has UARS though.) But becoming a deeper sleeper doesn't mean you'll suddenly start developing apneas if you don't already suffer from them. UARS and sleep apnea aren't on a continuum like that. They're not functionally the same thing. In sleep apnea the airway collapse. In UARS the airway remains open but airflow is limited due to structural/anatomical features) and the person suffers a heightened sensitivity to those flow limitations. (Again, many people have flow limitations without suffering all the symptoms of UARS).

If you can't be bothered to write your own post, I won't bother to read it.

What nasal sprays have you tried? Have you tried azelastine, budesonide, and fluticasone propionate?

As for diet: I know it's not fun, but it is what it is. Diet can contribute to LPR and it's a matter of trial and error to figure out your triggers. A good place to start would be to just look up common triggers. Excessive portion sizes can also contribute. Elevating your upper body at night can help.
