vibratory snore

What exactly does this mean on my encore report? My ahi was .9, and I had almost no leak spikes, and yet my vibratory snore is at the top of the graph. If I am opening my mouth, wouldn't the leak go up? I use a nasal pillow mask and if I open my mouth the air all shoots out. I feel great, but just can't figure out what it means. Thanks

I wear a FullFace mask which allows me, when necessary (nasal congestion, for example), to open and breathe through my mouth without leaking any pressurized air and possibly compromising my therapy. I suspect that you, with a nasal mask, would see leak spikes if you are opening your mouth and snoring. However, I am not 100% sure as I have never investigated this possibility. Someone experienced with a nasal mask and snoring needs to address this.

I rarely have any VS (snore) events. When one occurs, I can usually and confidently attribute it to one of two causes: 1) my hose rubbing against my headboard , or 2) coughing with my mask on. My hose rubbing against my headboard occurs only when I have turned on my machine and am getting into bed. I try, in the dark, to keep the hose (it is attached with a cord to a slat in the canopy of a 4-poster bed) from hitting anything when I lay down and attempt to get into a comfortable side-sleeping position. However, my rare VS events indicate that I am not always successful.

BTW, I do believe that some CPAP users may have real "honest to goodness" snores. You might be one of them. The way to check if your machine is registering "false" snores is to make sure that your hose does not rub against anything while your machine is turned on.

You might want to update your machine type in your profile as that machine only reports compliance hours. Your posting indicated that you are using a data capable machine with EncorePro or EncoreViewer reporting.

I have previously posted data which demonstrates that , with the same Respironics machine settings, different masks present very different vibratory snore characteristics:

From my post:
viewtopic.php?f=1&t=42646
the figures given for each mask are the average of VS indices for the indicated number of nights, the range of values, and the standard deviation



which demonstrates that both for AutoPAP 6 - 20cm, and for fixed pressure 11cm, the Activa nasal mask products virtually no VS (most surprising since with associated mouth leak, more snoring would be expected), while two full-face masks, and in particular the UMFF, produce considerable VS.

I will soon be adding to the above post additional data, at AutoPAP 10-20cm, showing the following average VS indices:
Activa: index 0.0 (never any VS) for 20 nights
UMFF: index 2.7 (range 0.1 - 7.2, sd 2.1)for 20 nights
F&P 431 ff: index 2.7 (range 0.3 - 4.7, sd 1.2) for 10 nights.

As Cinco777 points out, "some CPAP users may have real 'honest to goodness' snores", which is undoubtedly true. Given the data I have collected, I cannot attribute my own VS to "real" snroing, nor to hose rubbing nor to coughing. I find VS to be a mask artifact. As I have also documented, I have encountered "runaway pressure increases" due primarily to VS which I doubt to be a physiological reality. VS for me, then, is a niusance and a "red herring". (ResMed autos also raise pressure in response to "snore", but this information is not reported without the add-on ResLink module.)

Velbor shows the following for a F&P #431 FF mask

F&P 431 ff: index 2.7 (range 0.3 - 4.7, sd 1.2) for 10 nights.

I have used a F&P #431 FF mask for the past five months (over 150 nights). I run my AutoCPAP with a constant pressure of 8. EncorePro Analyzer reports that my Snore Index (SI) for this five month period of time is 0.0. As I mentioned in an earlier post, I rarely have snores registered by my machine and when I do see them, I can attribute them to either hose rubbing or coughing. If there is an artifact with the F&P #431 FF mask causing increased snore counts, it must be an artifact that comes into play at higher pressures than 8 (based on my own usage and a SI of 0.0 over five months of use of the F&P #431 at a pressure of 8 cmH2O).

I have often seen the term " vibratory snore ".

Is there such a thing as a ' non-vibratory snore ' ?

I would think by definition a snore was a vibration of tissue causing the noise so why call it a " vibrator snore " when a simple " snore " would do.

Unless there is some other kind of snore.

Curioser and curioser.

Hm...what is vibratory snore? Never even heard about it...
