Can I get a SleepyHead analysis? Paging DeltaDave

Sure. Any information is good information, and the more the better.

Dave it didn't look like could IM you. Let me know how to get you file.

This is a VPAP S....so straight bilevel pressure. They won't vary. There is no auto adjusting mode with this machine.

Error. One of SleepyHead's bugs.

I have bafflement. Does not Sleepyhead say that this is an S9 VPAP Auto? So it is simply set in S-Mode?

SH does say VPAP Auto but OP profile says VPAP S and thus no auto mode. It also says APAP with pressure 0 -0 which is obviously an error. I am pretty sure Tom has the VPAP S. SleepyHead seems to have some bugs with reporting modes.
I have a VPAP Auto.
Here is what my machine says I am using..10 EPAP PS of 5 and IPAP 18max


But it has it wrong.. My settings are auto mode but EPAP is 9....PS is 4 and max IPAP is 20.
I did hit 19.15 max IPAP this night for a very brief period of time.

So for SH and this particular area shown...buggy.
I have not used my S mode on this machine to compare it to Tom's reported settings but I expect it would be off.
The statistics page of SH where it shows my RX changes and uses...those are off also.

Well, rumour has it that ResScan says it's an S9 VPAP Auto, too, so perhaps Tom picked the wrong machine type.

This also opens up some very interesting possibilities...

Then you have seen the reports... I was going on the machine chosen in his profile and trusting that he had it right. That's what I get for trusting.
SleepyHead still has a bug there though.

If you have time would you mind taking a look at this thread of mine?
viewtopic.php?f=1&t=81000&p=737152#p737152
I am still trying to learn about sleep wake junk or what I call awake/semi awake garbage. Most of the time when I see it I know for sure I was awake and the flow pattern is all over the place and I can pretty much chalk it up to junk.
This one in the thread above I don't know what to make of it. I don't remember any awake time at all. It was a rarity so I didn't dwell on it. Mostly just curious because I like to look for answers if I can find them. Always like to learn something when I can.

Given that there is some semblance of organization and considering location, I think I would go with "Sleep-Wake Instability" (usual disclaimer re: inability to determine sleep stages).

However, what did John mean when he said:

That tended to be what I thought especially considering the location. If I have clusters of centrals it is almost always associated with known awake/semi awake times right before I normally just decide to get up after laying in bed dozing "thinking" about getting up. That night I didn't remember doing it (most often I remember) but of course I don't expect to remember all of the "awake" stuff. I know that often I wake up with my back hurting like the devil (on my back) so I change position and go back to sleep. I have had times where I remember dreaming that my back was hurting really bad...maybe that was partly to blame when those centrals occurred.

Don't know what John meant. I have had rare (very rare) PB show up on my PR S1 reports and sometimes with associated central involvement (but not always) but pretty much for very brief times and never all night. In fact my central index long term is really quite low. None of the usual central producing suspects in my history either. Most nights my central component is either none to maybe a handful throughout the 7 to 8 hours and nothing to be concerned with.
That one night with 17 centrals in 17 minutes...totally not common for me so I don't worry about it.
Mild passing curiosity as to "why" but other than that I don't give much consideration. If it happened often...then I would start digging deep but since it doesn't...I just shrug my shoulders and blame it on the aliens.

Those 17 "centrals" looked a little more like the "real deal" centrals with real CSR than I usually see yet still not quite like I would expect to see with real CSR. Most of the time the difference is so glaringly obvious I can quickly discount them.

Thank you for your thoughts though. I was just wondering if maybe I was missing something obvious. This up close and zoomed in looking at each breath is not something that I am all that comfortable with deciphering. Not enough experience yet.

I bet that's what I'm getting. What I'm going to lose on this one is the capability to go 'Auto'. I'm not on Auto, I'm on fixed 16/12, but they thought of trying auto was intriguing.

So there are 3 possibilities:

• There is event misidentification and the centrals are obstructive;
• There is event misidentification and the obstructives are central; or
• Event identification is correct, the events are scored correctly, and there is a mix of events.

Rather than dial wingin' (jack up EPAP, assuming the events are obstructive, and see if they respond) or machine wingin' (stick in a back up rate and see what happens)(which "IMHO" is a bad idea cause if they're central they're going to get worse, and if they're obstructive, the present pressure settings may or may not overcome the obstruction, and if they (eventually) do then that would indicate that a backup rate wasn't necessary and dial wingin' was the appropriate (HAHAHAHAHAHAHA) selection), it seems like a much better plan would be to perform diagnostic testing with a Portable Sleep Testing unit. Something like ResMed Apnea Link Plus (since they seem to be ResMed fans) could reliably differentiate central from obstructives.

First....let me apologize if I had the wrong machine listed. I'll be careful when I edit my profile tonight. I have the new machine. BTW.....I'm kind of a prisoner to my sleep doc's prescriptions. My previous machine had an automatic mode, but I was on a fixed bi-pap pressure of 16/12.

So I got the new machine at 10:30 today annd was told it had a backup rate set to 8. Since (as usual) I was tired, I layed down for a nap about 12:30. I could feel a difference in the machine, as I had a sense of breathing in and out constantly and thinking "Hmmmm 60 seconds divided by 8 is like breathing every 7 seconds. That's a lot". And every once in a while I could feel I was not breathing when the machine wanted. But I didn't feel I was fighting the machine.

I didn't think I ever fell asleep but when I saw the clock it was 2 hours so I must have. When I popped the card into Sleepyhead, I saw some intersting numbers.

My AHI was 19.47, but they were all Hypopneas (which had always been close to non-existent for me). My OSA and CSA were 0.00

In addtion, for the first 1:15 my AHI was 29.86 but in the last 45 minutes it was 1.54

So I'm not sure if I just got used to it, and went with the flow.... or if the last 45 minutes were the time I was asleep, or what.....?

But the numbers on the last 45 minutes has me kind of stoked for tonight.

By the way..... I don't know how one goes about getting the lists of machines updated, but my new machine the S9 VPAP™ ST is not listed. And SleepyHead is not listed in the software

All items in the equipment drop down menu are tied to our forum host cpap.com. If cpap.com hasn't ever sold it then it won't be offered as a choice. So there are some things that won't show up. It is just a limitation within the system.
SleepyHead is free so obviously no choice there.
Just add the S9 VPAP S/T to your comments section and omit the machine choice feature that doesn't offer your machine. Cpap.com has never sold the VPAP ST
You can include Sleepyhead in the comments if you wish.

Events at the beginning are new. That usually (most often) wouldn't be a REM period; yet, you have other data that suggest that the events could be REM-dependent. Consequently, the mystery continues-- position-dependent or stage-dependent?

While this is promising news, it still may not be Nervana (the neurological equivalent of Valhalla)(the upper Westchester County version of Brooklyn).

BiLevel with a Back-Up rate is going to "generate a waveform", and mechanical breaths are only about 50% efficient as spontaneous breaths, so a little more work may be needed.
