Are isolated "gasps" arousals?

Obob, I'm following your thread with great interest. Do you feel better today?

More RERA-like flow limitation waveforms are shown in this post I just added onto my thread.
It might help new people learning how to interpret these zoomed images (such as myself).

Thank you AQ.  That is helpful for me.  I also "slept" with the PR APAP for some time last night and this morning to meet compliance.  Interesting the difference in flow waveforms between the two machines.  I haven't shown either but the difference is astounding: VAuto almost all well rounded while sleep wave forms with the APAP are almost all "chair"(see fig. at beginning of this post) or "plateau"  (classes 4 & 7 in the chart you show.)  Actually, following the VAuto sessions I didn't actually sleep very much while on the APAP -- perhaps 30 minutes out of 4.4 hours, the rest being a rollercoaster of mostly central apneas typical of my SWJ.  I will certainly examine the references in the google search that you linked.  Maybe I can find something to educate my sleep doctor there.

Thank you Dormeo.  Yes, surprisingly I do feel better today in spite of only a few hour of quality sleep with the VAuto, the rest with trash "sleep" using my APAP, but certainly also the good result has me hyped.  Time will tell but certainly feel optimistic. (A turn around!)

if the spikes in your screenshots are truly isolated (i.e., not repeating somewhat regularly), they could simply be sighs or they could be recovery breaths after a period of flow limited breaths. I think both have been mentioned earlier in this thread.

I don't think the gasps are periodic, sheepless, but need to look at many more examples (have over 11 months worth -- not 9 as I first guessed.)  Interesting thing I saw this morning with the VAuto is that although the flow limited inspires are gone I still do have gasps.  Have to keep an eye on these as I (hopefully) get more similar results.  Thanks again.

By the way, it turns out that the 3rd hit in that google search is the actual paper (for me at least).
I'm surprised google doesn't make it #1 since the match is perfect... but that's another story for another day.
https://pdfs.semanticscholar.org/0c30/43...370be1.pdf

You'll be happy to hear that "Subject 1" has results most like yours and was considered to be "the most normal of healthy males" in the control group.
Look at the final figure in that paper to see the distribution of waveforms to see the distribution histogram "match"..... then scan through the paper to see who "Subject 1" was.

That's only worth what you paid for it.  I have got very little interpretation experience (to date) but I CAN read.  ;-)

P.S. That paper is from Finland... interesting coincidence considering my initial Norwegian/Scandinavian youtube video.

That was an excellent paper apneaquestions

Dude! I told you so.

Give me a chance, and we might even do better.

"... or 'Your Dudeness' if your not into that whole brevity thing."

Actually I come from a different era, but appreciate whatever honorifics I can get.  I remain in high spirits even though last night's trial with the VAuto was not quite as stellar as the night before.

   

Aside from the SWJ stuff the over-all picture looks pretty good.  However, looking at the 2 minute flow rate, VAuto looks a bit more like the results from the PR APAP machine -- variously flattened tops (but not as bad as with the APAP.)  Note also from the attachment here that there are more flow limitations recorded.

I'll reveal (most) of the crazy things I do in my mostly futile quest for a good night's sleep in due course, but for now just three things:
  • Am splitting the night between VAuto and APAP until Dec 26 (feel Big Brother is still watching my every move) so, about 4 hours/night for each.  Even the lower quality sleep (or semi sleep) so far seem to be agreeing with me.  Fact, think I'm feeling better today than I have for several months.
  • During the night I take a small sub lingual dose of Zolpidem before every sleep session (each time I start or re-start the PAP machine.)  My hope in doing this is to shorten the wake-sleep transition.  I've not discussed this with anyone -- maybe it works.  Dosage is 1-2 mg/session.
  • Since Thursday I have used a nasal spray containing xylitol and capsacin (XLEAR MAX, just what I could find that wasn't even more ridiculously expensive.  Read about this in comment by ragtopcircus in recent AB thread by tarah.  Thanks)  Used liberally, 5-6 times per day.  Don't know if this was the cause, but my rhinitis has significantly subsided.  Also think the VAuto helps with this condition.
 Here are APAP pictures for Friday and Saturday "nights" (for comparison.)  Not pretty:

So, Sleeprider whats next?

PS: Having lots of trouble getting the pictures where I want them.  Sorry.

Results from Sunday night.  Over all, very encouraging for me:
   

Two minute view of flow rate (FR) starts off looking very good:
   

But after about one hour FR begins to show signs of flow limitation (FL) (some recognized by VAuto but many not identified.  -- IMO)  Then it degenerates further to what looks to me like quite distressed breathing with increased respiratory rate (RR):
   

This is followed by somewhat better looking FR but still quite flattened tops indicative of FL (not shown here.)  

I'm surprised that the FLs that are recognized by VAuto do not increase IPAP more.

What do you think?
