Got Additional Sleep Study Data

[SleepySandy]

I was able to get a bit more information from my sleep lab. I'm including scans of the study summaries as well as the new "Respiratory Disturbance Event Summary" reports. I'm still trying to process this new information.

Any thoughts you have regarding my new information will be much appreciated. I have an appointment with a new sleep doc tomorrow, so please share any questions you think I should ask him.

Sandy,

Is your data online or viewable anywhere ?

Happy to take a peek & offer humble opinions

Hi dsm,

You can't see the scans? I posted 4. I can see them. What am I doing wrong?

I uploaded them to photobucket and pasted the image links.

I'm not going to get much help if no one can see them...

Help.

Sandy

[dsm]

Perhaps they are in a sep thread you started ?

I can't see any links to images or anything in this set

Cheers

When I pull up this thread, the images are there. I have another computer and checked from it as well, thinking somehow I was seeing the images because they're also on my laptop. I was able to see the scans both places.

I've never posted images before, so I don't know what I'm doing wrong, especially since I can see them.

I'll type them instead. It's going to take a few minutes.

I see the images, and well, welcome to the UARS club.

There is a great article on line about Upper Airway Resistance Syndrome, titled Upper Airway... etc. ten year later. If you google UARS it should come up. I find it a nice comprehensive explination of UARS. I feel better since I started on cpap, and cpap seems to work for most people with UARS. I already have fewer headaches, am less cold (cold extremities and poor cold tolerance are common symptoms of UARS,) and much less tired.

Let me know if you have more questions about UARS, not that I know that much, but I seem to be one of the few around here with that instead of sleep apnea.

DSM can't see my scans, so I typed the information.

The Respiratory Disturbance Event Summary data is below. My initial and titration study summaries are on page 2 of this thread: viewtopic.php?t=17322&postdays=0&postorder=asc&start=0

Goshes, DSM! The scans showed up fine for me. That's how I was able to make the comments I did.

[Slinky]

Say what??? I can still see the original scans, your comment, DSM, about not being able to see them (which I wondered about when I made my post right under yours) and now I can see the reports Sandy typed up - but "my" post is missing. The ghosties must be busy tonight!!! Weird!

[dsm]

I can see both sets now - possibly because of the distance (to Aust) I didn't see them at 1st - certaily others could.


The data is very comprehensive and very well laid out.

I was interested in the desats & the mean being 97% (roughly same as mine for my PSG last night).

I see the report registers a 3% drop as a trigger for a 'desat' in this report. Also shows a dispersion of them through various sleep stages & the rate per hour !.

Very informative.

The good thing is of course that your SpO2 nadir (lowest) is still over 90% & in my book that is good

The overall AI score is not bad but I see the HI & Centrals score is the higher part.

More later ...

DSM

[SleepySandy]

but "my" post is missing.

Slinky - Did your comments reappear? If so, can you PM them to me?

I do see about my numbers from Rachel and DSM.

I hope other comments aren't disappearing. I'm really intersted in feedback.

[dsm]

Heres a question for SAG or SWS

What is the significance of a REM Desat Index ? (allowing that this report sets the desat trigger at 3%).

I see in this report it shows this index as 27.1/hr while the NREM Desat Index is much lower (7.4/hr). My reaction is to assume that REM sleep triggers most of the desats ?


DSM

[dsm]

The report appears to be a very good one in terms of cpap effectiveness between the initial sleep eval & the titration part.

In sleep study AHI of 14 then with cpap titration 0.7 - that is pretty good as AHI goes. Also it shows zero desats during the titration night. LMs & PLMs show a very big drop as well. 10 CMS is a nice pressure to manage

I would be happy with that result.

DSM

[kteague]

No problem seeing the results. I don't know much about UARS, but bless your heart, your report speaks to how difficult things must be for you. May you find your treatment to be effective real soon and get the sleep you need to feel good again.

I have a question if anyone has knowledge about such things. In the breakdown of events by position, is there an explanation for why there would be events on the left side but none the right? Is this common to see? Guess I was wondering if there was some anatomical reason. I try to stay a lot on my left side because I was told it would help reflux, but if apneas are more likely on one side or the other, I'd like to know.

[SleepySandy]

I've had some time to review the Respiratory Disturbance Event Summary reports and I have a couple of questions:

This report is the first time I've seen anything about Central events for me. In my initial study, there were a total of 11 REM and 3 NREM events. Is there a threshold number of Central events that must occur in order to diagnose someone with Central apnea?

Does it seem odd that my entire titration study was done on my back? I've read other posts where the tech asks the person to sleep in different positions.

Does it seem odd that I didn't have any obstructive events during my titration study? I sort of think if they were moving my pressure around I would have had some. How else would they know what my lowest effective pressure is? Clearly, I have no idea how they do a titration.
