Re: pressure changes
Thanks Jay. Same SH version that I am using.
Now I expect my Adapt reports to show up the way that they do in SleepyHead and ResScan but I don't understand the OP's report with the UAs.
I haven't been able to figure out what the problem might be....or even if it is a problem. In this situation I am out of ideas and pretty much resigned to "I don't know".

Re: pressure changes
Without doing an exhaustive search, for me it would appear that all UA reported by Sleepyhead are likewise reported by ResScan and vice-versa. It also appears, for me, that all UA occur during periods of high leak (>30L/min). My search sample is fairly small, but the results seem consistent with the ResScan definition of UA I posted earlier in this thread.
In looking at the OP's SH post, I notice there is not a line for OA in the Event Flags box. Do you suppose this is a function of the machine type? Or, is it turned off? Or? Is yours the same, Pugsy?. I have a line for the flags even if there are no events.

Re: pressure changes
And that is as I would expect it but for the OP here...no large leaks and ResScan isn't calling the SleepyHead UAs as ResScan UAs...ResScan is calling them OAs (I think).Jay Aitchsee wrote:Without doing an exhaustive search, for me it would appear that all UA reported by Sleepyhead are likewise reported by ResScan and vice-versa.

Re: pressure changes
I have all the usual events on my Adapt SH report even if I don't have any of those events flagged and my SleepyHead version is the 9.8-1 open GL version just like the OPs.Jay Aitchsee wrote:In looking at the OP's SH post, I notice there is not a line for OA in the Event Flags box.

I am wondering if there is a little SH bug going on here....a bug particular to the VPAP S. The UAs should be OAs .....
Hey Sharhamm....could you maybe find the time to get me a copy of your SD card and let me try my various SleepyHead versions to see what I might get? I have about 3 different versions that I can try.

Re: pressure changes
Re: pressure changes
Here's the sleepyhead report for the same night. I didn't know how to post both together, sorry about that.
I would be happy to give you a copy of my SD card if you will tell me how to do that.
One of the things you've been talking about is that perhaps the VPAP ST is not recording OA's. They did back in Dec. and the last one a week ago. Unfortunately the graphs for December no long show and the one a week ago was when I forgot to put the SD card back into the computer overnight so I only have the summary.

Re: pressure changes
I don't see a leak at this time, but it's possible that a very small, but very noisy leak occurred around this time. Certainly there are no events at 22:34. There is a break in the leak graph at around 20:40. Is that when you woke with the noise?Sharhamm wrote: 2234 (approx.) awakened with whistling noise in the mask.
There's a gap in the leak graph that indicates the machine was turned off and back on at more like 23:05 to 23:10. And there's a tiny leak around 22:45 or 22:50. It's possible you were breathing with your mouth open just a tiny, itsy-bitsy bit during that leak. And as pugsy said, for some of us, even the smallest bit of mouth breathing can lead to a very dry mouth.2334 awakened with extremely dry mouth and throat
There is a medium-sized leak that lasts from about 01:40 to 0:1:55 or so. This leak looks like mouth breathing even though the size of the leak is well below the 24 L/min RedLine. In other words, this leak is NOT large enough to affect the efficacy of your therapy. However, the machine compensates for a medium sized leak by blowing additional air into the "semi-closed system" in order to maintain the desired pressure level. Once you closed your mouth, it may have taken the machine a few breaths to detect the decrease in leak rate and appropriately decrease the amount of air being blown down your throat. It's quite possible that some of that extra air wound up as the large air bubble in your mouth at this wake.0210 awakened with large air bubble in my mouth
If you were particularly restless between 03:00 and 04:00, it's possible that some of those apneas and hypopneas are sleep transitional and/or misscored wake breathing.From then on a very restless night with tossing and turning and mask adjustments.

I don't know if this is relevant because I don't know the ins and outs of the S9 VPAPs as well as you.
In the screen shot of last night's data that Sharhamm included in his last post, ResScan indicates that the machine is an S9 VPAP ST, which is NOT the same as an S9 VPAP S. The ST does have a back-up rate mode and is a more expensive machine than the S9 VPAP S and the S9 VPAP Auto; the ST is usually not prescribed unless there are documented problems with central apneas. Is it possible that the VPAP ST scores events in the same fashion that your S9 VPAP Adapt, which is also used to treat folks who have problems with centrals?

Re: pressure changes
I caught the ST thing this morning and have asked for clarification since the profile shows the VPAP S and that had me confused.robysue wrote:In the screen shot of last night's data that Sharhamm included in his last post, ResScan indicates that the machine is an S9 VPAP ST, which is NOT the same as an S9 VPAP S.

I asked that in a PM where I explained how to send a copy of the SD card to my private email.
I think that the ST is behaving like my Adapt and that's likely the explanation for the mysterious UAs. It doesn't differentiate between centrals and obstructives and calls both "Apneas".
I suspect that if I can run her data through my various versions of Sleepyhead that we are going to see what I see on my Adapt reports.
But she says that back in December it did flag OAs...so that doesn't make any sense...but she doesn't have those old reports to confirm.
If it is doing like my Adapt does....it (SleepyHead) shouldn't have shown OAs in December.
So I think you are correct and the UAs shown are just SH doing what it does with my Adapt reports...but the comment about SH showing OAs in Dec bugs me if the same machine has been used all this time unless maybe a different mode??????
I still would like to run the data through some of my SleepyHead versions though....because I am curious.
According to SleepyHead it says the S9 VPAP STAMER model (which I think is ST-A and I don't know what MER means) used in VPAP S mode...so no backup rate and the report flow rate looks like VPAP S pressure and flow.

Re: pressure changes
From the S9 VPAP Manual.
Which implies that in the S and ST modes there is no differentiation of type of eventsIn VAuto or CPAP mode, these VPAP devices detect both obstructive and central sleep apneas (CSA).

I saw that SH didn't show it as a S the other day, but didn't quite parse out what it said, resscan shows it better.robysue wrote:I don't know if this is relevant because I don't know the ins and outs of the S9 VPAPs as well as you.

indeed the ST is a different animal, and you're very likely right.
