What do these silverlining numbers mean? Need help.

The events that are reported Apneas, 2 Hypopnea etc - are these events that were detected and stopped ?

I have read numerous times throughout this forum that you need an AHI under 5

I have now been using a 420E for 2 nights and my AHI is > 50 (fivity) each night.

So is my CPAP treatment working and stopping these events when they occur or should my CPAP treatment be reducing my API to <5

Seagull:
I responded to your e-mail that included the Silverlining data file. Did the info help at all (I hope)? Also, have you had a chance to talk with your Dr. about your treatment?
Hope you are well.

I am just starting to download and dig into Silverlining on my 420E.

A really basic question...
What is a "run" ?

I seem to be able to view my data when the computer and machine is hooked up, and I seem to be able to save something, but when i try to open the file later (or even the demo files) I get an error message and its says it can't open the file(s). Anyone else have a problem like that?

Snork,
A "run" is defined in the manual (page 33, or 37), it's a number of consecutive flow limitations. You'll get an option of choosing a manual if you click on the question mark in the opening screen.

Instead of clicking on the file name, and hoping SL3 will launch, open SL3, and then use the "file, open" option to select the file. That should solve the error problem.

I had this problem under the following conditions:
Win. 98, older version of SL3.

I don't have it on win2k and version 3.6

I have been attempting to open the files from within SL, but I am running SL3 version 3.2 on Win XP. I am wondering if its a problem with an older version. The error message is:
Silver lining2 unhandled exception (open file()[sl.cpp]

My workaround (thanks to a tip from the forum) is to use the export function while the machine is still hooked up and save it as a text file. At least I can capture the basic data.

Any other workarounds for this problem?

Yes, It did help. I knew I would get in trouble for changing the settings constantly! I haven't changed them since!
Also, I hate to say I eat, read, watch tv, and basically live in my bed, except now when I am in the computer room or when I am outside, or gone. I do realise this is not good sleep prep. I also eat late.
I eat late in bed while watching stimulating tv shows. I know that goes totally against the sleep rules.
I too, like waikiksnowman, wanted to know if these figures are what the machine responded to.
Also I don't have anyone to talk to about treatment except you guys. I went to the sleep center right before my insurance ended. My nurse practictioner sent me. I never met the Docs. They are in Atlanta and I am in Tennessee.
That's why I wanted an auto.
Thanks WS. Dee

waikiksnowman and seagull,

Are you sure you're looking at the right side column, the one which says index/h? If you are, then you are getting far too many events.

The auto should function on a low range pressure that keeps your airways splinted open, so that most of the apnea an hypopnea events are avoided, or a the very least, preempted. A total index of 50 (50 events per hour!) is totally unacceptable. With proper therapy, the events should be reduced to less than 5. And some of us feel distinctly better when the events are less than 3.

snork
I had problems with version 3.2 on windows 98!.

Do your best to get 3.6.
In the meanwhile, try the following:
Give the files old fashioned 8.3 names without spaces, (XXXXXXXX.YYY) and put them in a dos style directory (eg. c:\sl3\patient).

And maybe try to unistall and reinstall the 3.2. into a very primitive directory structrure (not into "program files"\sl3\)

osij, No that was the left column. The daily number of events. The right column looks fine. A lot of runs and snores though.

I have been using my new 420E for the last two days/nights. I used my Ultra Mirage Full Face Mask for the first night and got much higher numbers of every categories (Apneas, Apneas/CA, Hypopneas, Hypopneas (FL), and Acoustical Vib) except for Runs compared to the second day/night with my Swift. The Ultra Mirage FF leaked alot more than the Swift and the leak graph was more eratic than the Swift's. I am getting effective therapy numbers for the Swift but not the Ultra Mirage FF but my wife complains about my snoring/puffing noises with the Swift but not the Ultra Mirage FF.

What is the significance of the Runs number? With my Ultra Mirage FF, I had an Index of 17.6 for Runs and for the Swift, I had an Index of 35.2. Also, I did change the pressure increments to .5 and the IFL1 to off before I used the Swift. Is there anything I need to do to decrease the Runs number?

You can't compare the masks when you made two other changes at the same time.

IFL1 is the switch that define the reaction to flow limitation runs. What made you turn IFL1 off?

I turned off the IFL1 because I thought that I was having the pressure run off.

ozij · Post by **ozij** » Sat Sep 17, 2005 12:55 pm

I'ld try each mask for at least a week, with the same setup as the other mask.

Can you tell me what the leak graph should look like if the masks is 'perfect' no leaks

Also what does Leaks Max (l/s) and leaks (l/s) Mean ? what is 'l' and 's'

My Leaks Max seems to stay flat at about 1.2 .

And now heres a mystery in perception.

Having been getting disastrous results with my new Ultra FF and Mirage Swift Nasal Pillow masks (AHI > 50 0 ) and the leaks (l/s) line looking like an earthquake with a Richter Scale of 10. Out of desperation tried my very very old
ComfortClassic Mask never used before with my 420E. With a constant CPAP pressure of 12 it appears to leak like a sieve. I wake up after about 3 hrs with the seals flapping like the main sail of a yacht. - feeling so uncomfortable and needing to replace it with the FF mask for the rest of the night. This I should say feels quite comfortable an appears to me to be leak free.

OK when I check the results with silver lining of the nights battle , I find the session with the ComfortClassic Mask has a virtually flat leaks (l/s) at approx 0.7 and AHI 4.7

Whereas the session with the FF masks leaks (l/s) which zig zagz between the extremes of the scale the AHI >30

The above is true now for 2 nights in a row - same senerio

Go figure

In both cases now I am tapping up my mouth.

What do these silverlining numbers mean? Need help.
