I don't understand the mechanism by which a bilevel would "allow" the CAs to go away. All I can think of is that a higher PS would allow for a more complete exhalation given that there is less relative pressure during the exhale. I suppose a high IPAP blast with an ASV would be another way to have ...

. Hmm, an ASV/bilevel, I hadn't heard of that. I assume by PS you mean pressure level. Anyway, that would make sense based on your reference to PS/EPR. In regards to figuring out what causes mine, it would seem to make sense for me to reduce my EPR (say, to 1) just for investigative purposes. If I ...

Also to be kept in mind is that bi-level machines are MUCH more expensive and there are usually strict insurance requirements before they will pay for one. Usually, the doctor has to certify that you have tried and failed on a regular cpap for a reasonable amount of time and he has to recommend tha...

I did not read through your long thread, but I am sure it is in there somewhere: Are you using EPR. If so what setting,1,2,3? EPR can cause CAs with some people. EDIT: If you have not tried running without EPR, I would. Won't hurt anything to give it a try. Hi Lilly, yes my machine --Resmed AirSens...

Hi all, it's been a while, but I've been dealing with labyrinthitis for almost 7 weeks now. It came on me suddenly one day, and has been quite an ordeal since, with balance issues and all. Still dealing with it, and getting vestibular therapy. In the meantime, I haven't been able to get my AHI score...

They called it mild/moderate because the events were not that bad or long, or something like that. the mild/moderate/severe rating of apnea is purely based on your uncorrected AHI. there's no measurement standard for the individual events, aside from the 10 second minimum duration. That's interesti...

Whatever they call it, 22 events/hour is significant. It's like being poked almost awake 22 times an hour throughout the night. No wonder you are tired. Some of these doctors piss me off with their ignorance. Mine told me anything under 6 is "great". Wonder how she'd feel if I went over to her hous...

I've been trying my nasal mask again for a few nights. I have to strap it pretty tight to get a good seal. I get more leaks than with a FFM, but my AHI is down quite a bit using the nasal (I think I know why). Keeping a good seal, in my experience, is easier with the FFM than the nasal. Hi Mudrock....

what she said (points to OkyDoky's msg) the leaks aren't therapy compromising, though if there had been any apneas during them, the machine may not have been able to tell which type they were, and might have reported an unknown apnea. but leaks certainly can disturb sleep to a large extent. Good to...

What I see is that almost 19% of your time on the machine you had large leaks. Leaks can cause arousals and false CA's when you are holding your breath and tossing and turning, so I wouldn't be concerned about the increase on the numbers. It's probably not a bad idea for a small minimum increase bu...

Hi all, if anyone has any feedback here, it would be welcome. On the night of 2/17 I think my sleep was pretty good, as I felt rested and had good mental energy. And my AHI was low as well. On the night of 2/18 I had an AHI about 3 times as large, and much higher leaks, and felt foggy-headed the nex...

My speculating so far have been concerning mask leak and AHI correlation, I'm curious as to whether you've gone back in sleepyhead to those days and looked at what was actually happening with AHI and leak. ah, good question palerider. No, I haven't had time to look at in depth. But that would be in...

As for the silly arguments, my arguments regarding CPAP with you have been over serious matters. There's a much better way to educate, and it's to have a more respectful tone. Such as---don't call them silly arguments. Although I've learned more what I don't know, so my speculation and arguments wi...

no "mea culpa" from you? mea culpa, mea culpa, mea máxima culpa. you actually DID ask someone for instructions on how to set your machine, and someone answered... you'd be wise to pay attention to what OkyDoky says, she gives good advice. again, should you ever want to learn things, instead of ente...
