Is it "snore" or mask cushion vibrations?
Is it "snore" or mask cushion vibrations?
This question is especially directed to S9 Elite and S9 Autoset users.
It seems to me that my "Snore Index" on the ResScan graphs, often, originates from the vibrations of the Silicone cushion in my mask.
Is it possible?

You can test it to see. Put on your mask and turn it on while noting the time. Clear you throat, cough, move the hose in various ways mentioned above. Give it 5 or 10 minutes, turn it off and read the data. Works on the Intellipap and it should on the Resmed.

Re: Is it "snore" or mask cushion vibrations?
Here is something from a past post here:
RERAs: Respiratory effort related arousals. Episodes that are not apneas or hypopneas, often related to loud snoring, that generally do not cause a decrease in oxygen saturation.
Vibratory Snore: How many times the machine *detects* snoring. However, its pretty inaccurate because the sensor can pick up a lot of artifacts such as dragging the hose over covers. If you have a cold, it can cause snoring like vibrations or mask issues can also cause a higher number especially prong or pillow masks.
A personal example of this is I am using a PR APAP, in my case it was giving me erroneous VS numbers because my nasal pillow mask wasn't angled just so, and one side was vibrating with each breath. Its important to figure out what the cause is, because my high VS made my APAP increase the pressure (its one of the factors the machine uses to decide to raise or lower pressure on the APAP, which ended up giving me a higher AHI. But fixing the mask solved both the high VS resulting in needing lower pressure and that reduced my AHI.

Re: Is it "snore" or mask cushion vibrations?
I have no difficulty believing that mask farts show up as snores. I'm not quite sure what to do about it, though.
Maybe some experimentation while awake can help you figure it out if you can force some mask farts.

arcangel, I must be a bit off posting this conversation since my sleep specialist (MDs in Pulmonary + Internal) would not even take a look at my ResScan data from my APAP or any CPAP, saying that since CPAPs diagnose on the basis of air flow, the data are for the birds. Only PSGs with the appropriate sensors could provide reliable data. He also relies on the Apworth Sleep Score. He is ready to loan me a complete at home, unattended sleep study equipment to see if the results correlate with my ResScan data from my APAP.
ArcAngel, when your dog is going to wake up and open the eye? Have you noticed that I have elevated your status from a boring angle inside an arc to an Angel who guards the Arc of the Covenent?

Re: Is it "snore" or mask cushion vibrations?

Some thoughts on this - the modern cpaps as best I understand use airflow disturbances detected with pressure transducers to determine snore. In the early days they actually used more conventional microphones but there is quite a difference between a sound detecting device & a pressure detecting device.
Some of the stuf you can read via google is likely to refer back to when microphones were used.
Either way I guess it is possible for some hose rattling & seal flutter to appear as snoring vibration. After all the machine is often picking it up 6ft from where it originates.
Years ago we had discussions on this issue - I recall that snoredog had some good opinions on it.

Re: Is it "snore" or mask cushion vibrations?
I don't always look a the Snore graph though I do pay attention to the Flow Limitations graph. Sometimes I see a clear correlation between the Snore and Flow Limitation graphs in ResScan, sometimes I don't. I have been having problems with 'mouth farts' from the cushion on the Quatro FX. I have some mask liners coming and if the liners decrease the problem, it will be interesting to see if the graph shows less 'snoring'.avi123 wrote:It seems to me that my "Snore Index" on the ResScan graphs, often, originates from the vibrations of the Silicone cushion in my mask.

Re: Is it "snore" or mask cushion vibrations?
Your MD is a fool. Yes, a PSG is better quality data for the one night every x years that you are in a sleep lab. It's the best data that he doesn't have for 99.5% of the year. Absolutely beautiful data that's not available for your actual sleeping conditions in your own bed, sleeping normally, not hooked up to wires in a strange bed with a rude sleep tech, etc.avi123 wrote:

arc, when your dog is going to wake up and open the eye?
The CPAP data may not be as detailed as a PSG data, but it's all you have for 364 days out of the year. If your CPAP shows 10 120 second obstructive apneas per hour, you've got a problem no matter what happened in your PSG. Yes, you may not want to panic when it shows x apneas per night, but it's got airflow diagrams. It may be inconclusive some of the time, but very often it's VERY conclusive.
Funny that he only is willing to look at the data that generates revenue for the medical mafia, isn't it?
I noticed a guy under the street light in front of my house one night. He was crawling around in the grass searching for something. He was obviously drunk. I asked him what he was doing. He said he was walking home from a party at a friend's house and he dropped his keys so he couldn't get into his house when he gets home. I thought, "well, at least he's not trying to drive home." I helped him look for his keys for about 10 minutes.
Finally, I asked him exactly where he was when he dropped his keys. He pointed down the street and said, "I stumbled into those bushes over there where it's dark." I asked him why he's looking here then.
He said "the light's better over here."
Your doctor is insisting on looking for your data under the street light even though you were in the bushes when you dropped your data.
When the dog's awake, she wants to play and I can't get on the internet.

Even if I see a correlation between the Flow Limitation and the Snore Index graphs they both could originate from mask seal flapping and not from snore.

Re: Is it "snore" or mask cushion vibrations?
AVI, I am not sure that it is from vibration (though wouldn't be suprised). My snore index is not as spiked as yours and my wife says I nolonger snore.avi123 wrote:fiberfan wrote:I don't always look a the Snore graph though I do pay attention to the Flow Limitations graph.

As I am at work right now I cant post a recient chart but here is a link to see one of my charts with a snoer index.

Re: Is it "snore" or mask cushion vibrations?
Jabman, I looked at your graphs and IMO you don't have OSA b/c the definition does not apply. Could be narcolepsy?
Since I don't get a satisfactory answer to my question I am removing my graphs which will also remove them in your quote.

How could you say I don't have OSA? I was Dxed with 71 events an hour with hardly any centrals, since putting on the mask I have done great. It's not narcolepsy.avi123 wrote:Jabman, I looked at your graphs and IMO you don't have OSA b/c the definition does not apply. Could be narcolepsy?
