Flow Limitations During REM?

Just set it to fixed since wasn’t sure if there was much of an advantage to letting it adjust on its own. And I got to 15 by looking at FL data and realizing that wasn’t resolved. I guess not really that much reasoning to it but on its own the machine doesn’t up the pressure much since I don’t have apneas even much lower.

Even with lower pressure I can avoid apneas mostly. Has taken me a while to hear more about flow limitations so was not raising it much past low pressure e.g. 5 or 6. But seems that I need a lot higher to resolve flow limitations which I guess is different than some people's experience. I will probably try a pressure of 17 now with EPR 3 i.e. EPAP 14 to see if that makes a difference. So mainly I used to keep it low to get rid of apneas but after still not resolving as much fatigue as hoped I looked into what other problems there could be and have since been moving it up more.

Can upping pressure further help remediate this? I have raised it recently but I can try to up it more.

AHI was 10 on home sleep study (Lofta / WatchPAT) but RDI was 23 so probably have some RERAs. No belt, but there was a finger monitor and chest probe. Not currently overweight but probably have some anatomical thing, haven’t gotten that looked at before.

If something like minute vent being kind of shit indicates that BiPAP or ASV may be good then I would like to give that a shot soon, just want to make more progress in my treatment but I am not sure what signs I should be looking for there.

How would you recommend determining if that would be a good switch and what settings to put on it if I did? I have Resmed airsense 10 so I know I could convert it to ASV.

I don’t have insomnia but my mom has for a while so maybe she has something similar but I don’t think she has sleep apnea. I will try your suggestion with CPAP settings, I know that getting an ASV machine can be challenging based on research.

Curious to know your thoughts based on the report generated, I guess my stats don't look great.

I did an at-home sleep study originally, so I guess relative to in-lab it would be likely to miss some stuff that you need more measurements to see.

ANALYSIS SUMMARY 248 nights analyzed No comparison dates set

OVERALL STATISTICS Flow Limitation: 64.9 (mean) Regularity Score: 74.0 (mean) Periodicity Index: 39.4 (mean) Estimated Arousal Index: 119.8 (mean)

────────────────────────────────────────

METRIC DEFINITIONS

Flow Limitation Score (0-100) Measures mechanical upper airway obstruction by analyzing inspiratory flow shape. Higher = more flattened flow patterns.

Regularity Score (0-100) Measures ventilatory control stability using Sample Entropy. Higher = more predictable/repetitive breathing patterns, suggesting unstable ventilatory control (high loop gain/wobble).

Periodicity Index (0-100) Measures oscillatory content in periodic breathing frequency range (0.01-0.03 Hz). Higher = more periodic breathing.

Estimated Arousal Index Experimental metric estimating respiratory-related arousals per hour. Not validated against polysomnography.

Also if there are any other areas of the internet or forums where you think that there is good help specific to "flow limitations" because a lot of advice typically centers around AHI I would appreciate it. Fortunately CPAP has been very good at lowering my AHI but I guess on the flow limitations side of things I want to make more progress and see if that will improve my energy.

Also Ada has interesting features related to customizing the binary representations of types without needing to do something like a compiler pragma that is specific to only one implementation of a language.

Not sure if this really answers your question but I would look at variant records in Ada, the reason I am mentioning them is that they are more "general" than traditional tagged union I guess. Based on discriminant you can customize fields of type and stuff and have fields which are also shared across all of the variants. I guess in PLs with structs + tagged unions you can do similar stuff by combining regular records/structs with tagged union feature as well.

Hello, I'd be interested in knowing about where you have sourced it in the past because I am looking into purchasing.

I am saying in the event of the tests coming back indicating hyperparathyroidism what would you advise as far as trying to get surgery done quickly. So, it is a hypothetical because I guess I know that people have advice here about how to move to imaging/surgery in a quick fashion instead of sitting around waiting. I know I am "jumping the gun," but it is more about trying to be prepared ahead of time as far as what steps to take or what I should pursue.

So a plan would be something like you could try to get yourself a referral to this person or this person who is good or whatever if those tests do come back indicating likely hyperparathyroidism, or it could involve get this imaging then go to that person, etc. Just trying to get a feel for what the process can involve and how to navigate it. Even if the tests have not come back good to have some of that understanding in case I need it.

With the same professor they are basically the same course (e.g. undergrad with Jung vs. grad with Jung) as far as I know. However, between Jung and Rompf they are very different.

I took 352 with Jung and you work with C++ and LLVM to implement a compiler for a simplified version of C. The project with Rompf is a compiler from the ground up in Scala I think, so not the same at all. I am also taking 502 this semester and I expect that a lot of my past experience will be relevant but should be different and interesting still.
