Re: Please interpret my flow limitations - UARS is debilitating

Here are some links to the nights I slept with a Resmed Airsense 10 last month, at lower pressures and lower PS. Thankfully that machine also records flow limitations on a graph.Pugsy wrote: ↑Fri Apr 19, 2024 6:33 amMe as a person or the forum members in general?
Rubicon is much better at this thing than I am. I just dabble in it and I only barely understand the basics. When I see something like your report my eyes glaze over. I don't normally evaluate flow rates from the type of machine you are using and mainly I just look for awake vs asleep breathing. The other subtleties I leave to the pros which I am not.
They don't look "normal" to my eye as they appear to be "too pointy" and not rounded. Why? I have no idea.
It could be what the machine is forcing your breathing to be doing and not you yourself and when not using the machine your flow rate is more "normal" looking. I do know that there is a lot of evidence of awake/arousal breathing going on during some of the night both with and without flagging. I also don't know anything about whatever surgeries you have had and their potential impact on the shape of the breaths.
Might be interesting to see a cpap report from your old machine if possible to see if the breaths looked the same on an different more traditional machine.
And we wait for Rubicon's thoughts.
Edit: One more question....has any of your doctors seen these reports and if so, what was said?
Please see my latest comment above and click on the links to look at my wave form data. I hear you are good at interpreting wave forms and I could really use your help.
In order for that to happen, I will need:
I’ve had:Rubicon wrote: ↑Mon Apr 22, 2024 2:04 amIn order for that to happen, I will need:
As previously requested, a description of every OSA-associated surgery you've had;
A complete report of every sleep study you've had;
A current list of all medications;
A 2-week sleep log (AASM has one);
The Oscar files; and
The broomstick of the Wicked Witch of the West (OK j/k on that last one).
I think that’s a moronic statement to make, considering you haven’t elaborated on why you think I don’t have UARS. You asked me for all that data which took me hours to compile, only to skim over it and dismiss it completely.Rubicon wrote: ↑Mon Apr 22, 2024 10:10 amBased on the information provided:
1. Your conclusion that UARS is the cause of your difficulties appears unfounded. Indeed, there isn't any evidence of it at all.
2. Your sleep quality is about 30 times worse than it should be.
3. A sleep log would help to examine overall sleep hygiene (it only takes seconds each AM to do), or looking at the entire Oscar folder (you'd have to upload it to a third party server) and examining trend data could serve the same purpose. SleepHQ says you're sleeping from 4AM to 11 AM but those times can be screwy as data is observed in different time zones. At any rate, sleepy hygiene would need to be put under the microscope.
Sure, no prob.
there isn't any evidence of it at all.
again underscoring the concomitant need for arousals as part of diagnostic criteria.It is characterized by an increase in upper airway resistance and/or flow limitation leading to sleep fragmentation, resulting in daytime sleepiness.
"Not programmed"? He could have (and should have) looked at the raw data himself and manually made that determination. He could have overwritten anything that was "programmed".genz9000 wrote: ↑Mon Apr 22, 2024 6:20 amMy sleep specialist said himself that PSGs aren't programmed to pick up on RERAs and flow limitations accurately. It's something to do with the fact that outdated definitions of hypopneas are used, meaning more subtle oxygen desaturations aren't picked up on.
Page 23. Tell the cheap bastard to start:He said the only way to actually test for UARS definitively is esophageal manometry, but no one does that here (Australia).
But you know what that aborigine fuck is going to say?
The PIFMF measured by RIP allows for the most accurate identification of UARS patients when breaths are selected for analysis immediately prior to arousals.
is because there are quite a few players in the mix here.
