What do these silverlining numbers mean? Need help.

I slept 5 1/2 hours last night.

apnea events-2 And what is the point of the tallying
apnea w/cardiac-2 pressure events report:
hypopnea-7
hypopnea w/flow limitation-3 120 apneas 1.3
acoustical vib-72 110 hypopneas .04
run-55 1495 acoustical vibs. 16.5
1314 flow limitations 14.5
normal cycle- 83%
int. cylcle-8%
flow limited 9%
invalid-0%

I live alone. Does this mean I am still snoring??? Thanks in advance.

Yep, Seagull, you be snoring!

Take a look at your numbers again. Look in the extreme left column where it shows "index." These are the index of events per hour.

I can't tell from your post which numbers apply to which category very well so I'm not going to take a shot at trying to figure out your data just yet.

You can, however, add up the 'apnea,' 'apnea w/cardiac' and the 'hypopnea' index numbers in the 'index' column. The total is your AHI, per hour, for the entire duration that you slept. If this number is below 5.0, you are doing pretty good. If the number is higher than 5.0, you might have a bit of tweaking to do regarding your treatment. More importantly than these numbers, how do you feel during the day?

I'd say to not worry about the 'cycles' yet. Focus more on the apneas and hypopneas.

Which machine are you using? 420S or 420E? It is my hunch that you are using the 420E. If so, what is the range of pressure that it is set at? Also, which mask are you using and what does the leak line look like in your data. Is it a flat line, slightly jagged or, big spikes that indicate big leaks?

If you want to e-mail me a file that has a few nights of data in it, I'll be happy to look at it and tell you what I think is going on with you while you are sleeping. I'm not a Dr., but I've gotten pretty accustomed to understanding the data that Silverlining spits out.

Let me know if you want this and I'll send you my e-mail address.

seagull,
not sure what "acoustical vib-72 110" means; the two numbers confuse me.

If you go into SL3 in the Synthesis, on the bottom right of the screen there is a button that lets you generate a report. You can then cut-and-paste text out of that report directly into this thread.

At a guess which could be wildly wrong, I think (but I don't know) that you had 72 "snores". Or did you have 72,110 snores? (Not possible, I know.)

If you really are snoring that much you might want to try bumping your pressure by 0.5 at a time, watching to make sure you aren't making other numbers worse.

Sorry, I had this written in two little neat columns, left and right. and when I posted it jumbled it all together. Here it is again.

apnea events-2
(with cardiac)-2
hypopnea-7
(with flow limitations)-3
acoustical vib.-72
runs-55
This is what was on the left.

Then I was asking what is the point of the page that has a running tally?

120 apneas 1.3
110 hypopneas .04
1495 acoustical vib. 16.5
1314 flow limit. 14.5

Ok, will succeed, at the clinic set on 12, they got me to quit snoring. Do you think the auto is just not responding quick enough for the snores. I have it set from 7-12. I was titrated at 12, being the 90% pressure. I ranged last night only around 8 or 9. But had 72 acoustical vibes.

I have been using the comfort gel, and the leaks look fine. I had about the same results with the swift. I do have questions for later at how to read the leak results.

Seagull:
I'd still want to look at the dita file so that I can give you a (hopefully) thorough answer. Just send me an e-mail with your data file as an attachment.

I'll send you a private message with my e-mail.

I just bought and installed this software for my Knightstar 425, and all I can get is compliance data, nothing on apnea, hypnopnea, snoring, etc. Any advice or counsel on this would be appreciated.

I am not very good at cutting and pasting, but I may be able to figure out how to send it.
Hopefully these are little bitty snores.

I'm not Will Succeed, but I'm willing to pretend.

It sounds like your lower limit is too low. I'd raise it if I were you.

I'm fairly certain that an "accoustic vibration" isn't necessarily a full throated noisy snore. In fact, from what I can see the 420e can respond quickly so that you might barely start making a faint snore and then the pressure is increased and it cuts off. It would still count as an "accoustic vibration".

If I could ever stay awake long enough once I put my mask on I could probably run some experiments. But I keep falling asleep!

WAFlowers, You are sooo lucky. I can't get to sleep. I did up my lower from 7-8.

WAFlowers · Post by **WAFlowers** » Thu Sep 08, 2005 3:18 pm

I'm already reaching the point where if I lay down without my mask on I don't feel right. I went to bed very early the other night and was going to read for 10 minutes to unwind, but I had trouble relaxing because I was in bed without my mask!

I can imagine that I'll soon be completely "trained" to never sleep without the mask, and that the mask will trigger a sleep reflex.

Pavlov's dogs had him well trained; every time they salivated he rang a bell! .

It would still count as an "accoustic vibration".

My hunch is that WAFlowers is right with this but, I'd still like to see the data file. All you have to do is download the data from the 420e to your computer, the way you do when you hook-up the ocmputer to the 420e and save the file. Give the file any name that you want, and save it to your desktop so that you can find it.

Then, send we an e-mail (not through this system) to the e-mail account that I sent you and include the data file as an attachment. I'll open the attachment in Silverlining and see if I can help you figure out what is going on.

I don't know why the data for the 425 would be different than the 420E. The compliance data should include info on apneas, etc.

Do you have a tab labeled "Synthesis"?

Morpheus · Post by **Morpheus** » Sat Sep 10, 2005 10:02 am

Thank you for responding about this. Synthesis only provides compliance data and respiration rate, nothing on other info. I don't know if this is because the 425 is a bi-pap and the others are CPAP's. I was very much hoping to get the detailed info with the new software and am disappointed to find that I can't. Before I bought the software from cpap.com, I searched these boards in order to determine if this would work for me and had the apparently mistaken impression that it would.

My software came with manuals for the 425. You are exactly correct. It seems that additional data is not there.

Being relatively new to all of this (two weeks), I only know enough to be dangerous. I hope you find the answers!
