Resmed airsense 10 AHI readings

[cparke]

I've been using cpap and the resmed 10 for 300 days now. On the sleep report the AHI every morning shows 0.2 and has for several months now. If I understand what I’ve read correctly this is well within the “normal” range which is supposed to be below 5.0. Is that correct? And I feel like there should be some deviation in the number I get at 0.2 once in awhile but it is always 0.2. Am I missing something? Is the machine accurate? Or should I just be glad the reading is 0.2? Also the “Events per hour” after waking up usually read between 0.0 and 0.6. All of this seems good but I still feel groggy and lethargic in the mornings. Does anyone have any input or ideas to share?

welcome to the zoo!

yeah, that don't seem quite right. it is well known that we don't sleep the same way every night. there ought to be SOME variation there.

could you share some of the graphs with us? if you aren't using oscar, please try it so we can see what is going on-

eta: i seem to remember someone else having this problem recently. but i can't remember what the result was.

The default for overall average parameter is 30 days...it wouldn't be impossible for you to maybe have this overall average but of course it is odd. You can check using the software and see each daily AHI for sure.
But sometimes daily numbers don't fluctuate much or enough to change overall 30 day averages.
You can change this parameter...explained in the manual...to 1 day, 7 days or the default 30 days.

Now there is one thing you might try and that is unplugging the machine from the electric source for a couple of minutes and then plugging back in. This forces the internal software to reboot itself. Very similar when we reboot the computer to clear out the cobwebs sometimes. The prior model of ResMed cpap machines was well known to have a little bug in the internal software where the machine got stuck reporting the same thing every night. Rebooting seemed to fix the issue. I haven't heard of a similar issue with the AirSense models but you never know. Hurts nothing to give it a try. It won't change past reports but you can do it and then use the machine and see what the report shows the next day.
Bear in mind that anytime the power is interrupted like that then when the machine reboots will default to the 30 day parameter and if you want a different parameter you will have to reset it again to what you want.

eta: i see, i copied out of your text in a message. all i copied was the shortened part. got it now. thanks again!



grabbed the links from you and didn't think to check 'em!

thanks for the correction. i'll save out the proper ones.

[cparke]

Thank you. I’ll check out the Oscar. I will definitely try rebooting as well. Since I posted this I had a lengthy conversation with my brother in law and he told me to try changing the setting on how long I keep track of the information. Right now it’s set on a year. He pointed out that having it keep track one day at a time is probably gives better feedback than accumulating information over a year. So I’m going to change the settings to keep track of my nightly sleep information day to day. Thanks again I greatly appreciate the input and information.

yeah, that just may be it.

good luck!

Right now it’s set on a year.

I think this will likely resolve your issue to set it to something that is going to reflect variances more easily.
It takes some really big different numbers to change an average based on a year's worth of data. Will take forever to move off an average based on a year. Heck, takes quite a while base on averages for just 30 nights.

[cparke]

Once again thanks much. I have already found the info and suggestions from you both helpful. Hopefully with some of the data I’ve accumulated on this SD Card the Dr can give me some indication why I remain light headed and groggy in the morning as sometimes that is even worse than when I started cpap. I read on another board sometimes the lightheadedness is caused by a change in pressure in the inner ear and recommended seeing an Ear, Nose and Throat (ENT) doctor which I’ll most likely follow up on. The Resmed shows average pressure used (automatically determined by the machine I presume because until recently I never change the auto-pressure from 4-20 default setting) A few months ago I changed the high setting from 20 down to 10 with no change in being light headed then back up to 12 with no change in being light headed so now it’s back to default with high setting at 20. Still showed pressure used at 10.6 and still light headed. I saw a YouTube video that strongly suggested leaving EPR at 3 so EPR is always 3. I tried 2 for a week and no change in how I feel in the morning. The first three months I was on cpap I did not have this feeling. It’s like it began one morning and I can’t shake it which is part of the reason I’m convincing myself something with the pressure is messing with my inner ears. Hey, thanks again. I plan on changing the length of time the machine is keeping track of data from a year to a day at a time, tonight. Have a great Memorial Day weekend.

Inner ear issues aren't all that common with cpap use but they can happen when there is an issue with the eustachian tubes and/or dysfunction.

If it is related to cpap pressure at all (there can be other reasons) it is most likely going to be your minimum pressure that is going to affect it the most...not the maximum. Reducing the maximum doesn't really do anything if you never reach it in the first place.

Since people can have inner ear issues without even being on cpap we always suggest that people see an ENT doc about any inner ear or vertigo issues. The one thing I have seen suggested that a person could do until they see a doc is maybe take an oral OTC decongestant.
May or may not help but worth trying.
There is also a condition called BPPV Benign paroxysmal positional vertigo which can manifest itself in various unwanted symptoms...it's not related to cpap use and cpap doesn't normally make it worse or better.

let us know if you need any further help. that's why we're here.

If OP's machine is set with a minimum of 4, he/she is not getting the full benefit of EPR. What about raising minimum to 7? In my mind, this is significant in view of Pugsy's earlier comments. I hope one of the experts here can provide an answer.

if the OP wants the help, he'll be back.

and we'll help him.

Just because someone's minimum is set to 4 doesn't mean that EPR at 3 never ends up being used. If using the typical auto range default of 4 to 20... yeah, while at 4 EPR can't kick in but just as soon as the pressure starts to increase then EPR starts to kick in.
The majority of the time the pressure will increase fairly quickly and the machine will end up using a pressure where EPR does its thing.
I have seen reports where the minimum goes from 4 to 10 in about 15 minutes and never returns to 4...the machine sets its own new minimum of 10 and with EPR at 3 they get at least 10 inhale and 7 exhale all night long. The original minimum of 4 becomes a moot point.

We don't really know what the OP's machine is doing at whatever setting is being used because we haven't seen any detailed reports at all and he really hasn't asked for pressure advice at this stage anyway.
I won't go advising any pressure settings ever without at least seeing the detailed reports when available. I just won't do it. Not in any one's best interest to go making wild ass guesses.
Not to mention that sometimes increasing pressures willy nilly causes problems....just because someone on you tube suggests EPR at 3 is needed...doesn't mean it is and doesn't mean that the 3 EPR doesn't cause a problem.

The only time I will make a guess at pressure settings is when someone is using a machine that doesn't give us any detailed data to look at.
Anyone else must share the data before I comment on changing anything related to pressures beyond generalities.
