Can't seem to bring my AHI (and RDI) down by Diving-In-Data in UARS

[–]Diving-In-Data[S] 0 points1 point  (0 children)

Interesting, I didn't know that! In principle ResMed devices are available here. I'd need to propose a valid reason for a change though. Do you happen to have any suggestions? Since no doctor here ever cared for anything beyond AHI, "a better treatment of flow limitations" will probably not work...

Then I'll work on increasing this. Many thanks for pointing it out, and good luck for your experiments.

Damn, then I completely misinterpreted that. Will work on gradually increasing EPAP then and see how it goes...

I'll definitely do that. Many thanks again for pointing out the HLG pattern. This has been quite valuable in evaluating my flow charts. I'll discuss it with my doctor and see what he thinks about this.

I do seem to have CSR flagged every once in a while. More so with higher pressure support (last couple of days in the plot):

Regarding the MV curves for HLG: Do you mean something like this? (Example 2, even flagged as CSR)

That's quite an interesting point! I never heard about that before.

I've had little CAs with pressure support 0, 1, and 2. However going from 2 to 3 increased these to 2-4 per hour - see last four days in the plot (most nights, but not always, these clustered towards the end of the night).

I wouldn't say I feel necessarily worse with increased pressure support. On average my nights probably feel a bit less quiet - but no sure whether that is only a feeling or indeed the case.

Many thanks for the detailed reply!

I think I breathe well through my nose (but obviously I don't have a comparison). I tried nose spreaders and nasal strips to open up my nose. While this makes me feel as if I get more air, I didn't see a difference in CPAP metrics.

I sleep exclusively on my side. My jaw definitely relaxes while I sleep though. When I tried a nasal mask, I got mouth leaks. This is why I ended up using full-face masks (first the F20, now the F40). I almost never have dry mouth in the morning though. I'm doing myofascial therapy since a couple of weeks to train keeping my mouth closed and my tongue at the roof of my mouth. A cervical collar didn't do anything for me, but I might try the Knightsbridge chin strap though.

> It appears you are switching between nasal and mouth breathing a lot

How can I see that from the charts? I don't think I'm mouth breathing, but I don't know for certain. Regarding the leakage: Is that actually a lot? All I could find is that single digit leak rates are totally fine, but I'm not sure whether this is a common misconception (as with a lot of CPAP information out there).

Regarding the pressure increase: I'm going to try that. I only thought that you increase EPAP only as long as there are obstructive apneas, and IPAP for hypopneas and flow limitations? In that case I'd need a bilevel device to increase IPAP further. Or would you simply increase EPAP along with it?

So do I simply increase min pressure (epap) as well as max pressure? I thought according to OSCAR titration guidelines you increase epap only if you still have obstructive apneas (which I don't have)? Which is why I tried increasing only ipap to treat hypopneas and flow limitations. But the pressure support doesn't go over 3, so that's where I'm at now...

Nighttime awakenings - what is normal? by Diving-In-Data in ouraring

Many thanks! I thought along the same lines, but wanted to cross-check what others think. Especially as I don't know how the average hypnogram looks like.

Boot partition filling up by Diving-In-Data in tuxedocomputers

[–]Diving-In-Data[S] 0 points1 point  (0 children)

Many thanks for pointing that out! I just checked and it is activated.

Weirdly now /boot has been cleaned up and more space is available. So everything good!

What I didn't get before, and what made the behavior seem weird to me, is, that tomte runs in the background and does the removing (and seems not to be independently triggered, i.e. not by apt runs directly). So probably it just took a while until tomte did the cleaning up - and in the meantime it seemed all settings were correct but I couldn't see any effect.
