If you're having a lot of very large leaks, that AHI number may not mean much, because the machine can't always detect events during large leaks. It'd be great if you could download Oscar (see below) and post a chart so we can see what's going on.

Too funny!

Thanks for the additional snippet. I see what might be arousal breathing at 8:07:30. It's pretty hard to tell whether there are other bits of arousal breathing during this segment, or just perhaps some sighs. And it's hard to tell whether you're truly asleep for some of this, though I think yes. The...

You are not experiencing treatment-emergent central apnea, because you're not having any central apnea events. You may be experiencing some instability in your flow rate, though that isn't apparent from the Oscar material that you posted. You mention frequent arousal breathing, though that too isn't...

Oh good; I thought you meant your were tired all the time. But getting sleepy earlier at night isn't really a problem. For whatever reason, your body is shifting your schedule around on you. I'd say to do what it's telling you to do.

At 6.2, you don't get the full benefit of your EPR for some of the time. That's because the lowest pressure the machine can deliver is 4. So for consistent EPR of 3, your minimum needs to be at least 7. If you want to try an experiment, you could also set your maximum to 7, which would eliminate pre...

If your AHI and sleep quality are good, you can count your fine-tuning as a complete success. Don't worry about how your graphs look.

Are you tired during the day, or are you sleepy? If you're tired, you might talk with your doctor about tests to see whether there's something else going on. You might also review side-effects for any medications you've started taking since you started sleeping longer. And have you tried making your...

With an AHI consistently below 1.5, you don't need to give a thought to reducing the number of CAs that you're seeing. Keep your EPR where it is if it is comfortable for you. Don't mess with success!

With your current settings of min 4 max 7 and no EPR, you are spending a lot of the night at 7, largely due to your flow limitations. If you set your min and max to 7 with EPR of 3, your average pressure over the night will be lower, since your exhalations will all be at 4. But I'm all in favor of g...

Sleep HQ isn't giving me access to your charts, but given what you've said about them, I see absolutely no reason for you to stick with the changes you've tried out. Your AHI and FLs are worse with these changes, so go back to what was working better for you. Side note: Often when people turn EPR ON...

Yes, bumping your EPR up sounds like a good next step. You're still pretty new to PAP therapy, and sometimes it takes a while before it provides restful sleep. So I'd recommend you have some patience and see how things look a month or two from now. There's a decent chance you'll be feeling better. I...

Well that's encouraging! Stick with these settings for a few more nights and see how it goes. The next step I would probably recommend is to re-introduce some EPR. That will give you a lower pressure when you exhale (except when you're at 4), which might help with the residual aerophagia issues.

That's it; the change would give you more information. Who knows whether the information would be helpful or not; it'd have to be available before anyone could figure that out.

I hope you'll follow up on the periodic limb movement issue.
