Vibratory Snoring Index

DenverCathy · Post by **DenverCathy** » Sat Jan 06, 2007 2:23 pm

May I assume the vibratory snoring is not measured unless you have on a full face mask or other mask which covers the mouth? Just wondering about my 0 snore score on the Encore Pro with my nasal mask. Thanks!

False, it measures snores anyway, just dragging the hose can produce snores. If you don't show snores you are lucky, I'm not. The snores will also cause the APAP to raise the pressure trying to supress them. Jim

it is still scored, it just demonstrates the benefit of breathing through your nose.

If you are using a FF mask it is most likely done because of either chronic nasal congestion or mouth breathing, snoring is more likely to occur breathing through the mouth.

yes even movement of the hose can possibly score a snore but I don't think even if you were good at it you could move the hose consistently enough during the night to create a snore index.

My old UltraMirage Full Face mask used to sound like a bull frog as you breathed in and out, I'm pretty sure the machine was scoring mask "noise" as a snore, ever since I stopped using that mask my snore index has dropped dramatically.

Jim,
Sorry about your snores. It sounds like I lucked out. It's been several nights on some nasal mask (not sure which one) and narry a snore mark. Yea! At least that is going right. Now just to get my AHI down to 5 or below -- so far that's only happened one night out of 3 weeks and 4 different masks-- I'm usually around 8-10. Oh well. I'll persist.

Thanks for the info.

Thanks for the info -- the nosehose must be working! Interesting about the hose registering a snore.

What's your pressure set at?

If it's 17 or higher, the SI is disabled on my RemStar M-Series Pro.

So it could be you are still snoring, but it's just not recorded at your pressure rate.

It's set by the DME at 7, my sleep center study suggested setting, which seems to be working well except for the slightly higher than desired AHI's. Would increasing the pressure slightly help with that? I have the manual; I suppose it would tell me how to increase the pressure setting. What's been your xperience with increasing the pressure to lower AHI'? It makes sense it would work as long as I don't start puffing or snoring.

Bumping your pressure up by one or so wouldn't be the end of the world. (I'm not a doctor.) Just be aware that if you increase your pressure too much, you could start having central apneas and generally being uncomfortable, causing less restful sleep. So, I'd bump it up by 0.5 or 1 and try it for a week to see what happens if it were me.

At 7 it should be recording the VSI if you are snoring, so that's actually pretty good. I started off at 16 a few weeks ago, and my doc bumped mine up to 17, now I don't get that information any more.

I do agree with Blarg, although I would talk to your doctor before changing anything. (My Standard Disclaimer) It's not that I think changing anything by 1 will cause you any issues, but depending on your doc he/she may not be happy with you messing with things.

Do we serve them or do they serve us? Go ahead and turn it up to 8 CM/H2O. Reasons:

1) The accuracy of your machine is +- 1 CM/H2O. Therefore, you may be
running at 6 right now.

2) A pressure change from 7 to 8 is very safe. Remember you are not
dealing with a dangerous machine, like a curling iron.

If you are afraid of the doctor (as others, not you have implied), DON'T
TELL HIM/HER.

After what I have said (above) please note that I have not worked in the
field of medicine since 1985. Furthermore, I was a lab tech, not a doctor,
RN, NP, or RT.

My snore index has been through the roof since I have had a cold. I have been coughing and fidgeting with the equipment so I figured that would count a lot of snores.

I had noticed that my snores went up a little just before I got my cold but I didnt care since my apneas were almost gone and I feel good. My wife didnt notice snoring so I attribute it to the equipment moving aroung when I turn over and some adjusting during the night.

Primarily I was woried about my ahi with have been between 1 and 2 for the last 2 weeks (since I started cpap) and that is mostly hypopneas since I have only had one to 2 apnea events per night. One night I had zero!

Is the snore index something that I should be paying very close attention to?

Hmmmm. This is very interesting. I just got a machine that has software capability (REMStar auto APAP with CFlex set at 3).

My snoring used to literally raise the roof. But once I got the CPAP, my wife said the snoring stopped. My sleep study pressure is 10 and so far I have not changed it nor change the machine from CPAP to APAP.

As for my results over a 3 week period, most nights show well under 10 snores per hour. There are 4 days with between 20 and 30 and one night with 60. Sometimes the silicon outer layer on my mask vibrates. I wonder if that is what it is picking up?

My bet is that your post nasal drip is causing a light snore. The machine doesn't know whether it a "heavy" snore or a "light" snore.....it reads them all the same.
