That's what I thought originally but it's sticky and all a uniform color. Found the sound abatement foam if it's useful for others to see (ick I should've changed my filter more often). It's a much different color than the stuff within the pump, so perhaps it was just dust. :roll: IMG_0190.jpg

Looks like plain old dust to me {shrugs}

You just had a massive logic fail. (Unless your fan runs in reverse.)

Ah good point, but seriously dude you could be more respectful.

We're all going through this shit - that's totally uncalled for.

Nobody here can (or should) confirm that the particles you see is the sound abatement foam. However, on the RemStar, the filters were placed at the air intake, before the pump. The particles you found on the filter could *NOT* have come from any of the device internals. Thanks. True, but your specu...

I decided to take apart my (broken) old REMstar to find where this sound abatement foam is, and I think I found it inside the pump assembly. I recall seeing this crap on the filter and not knowing what it was. I think I breathed this in for years. Does anyone mind confirming that this is the same is...

Pugsy, how do you like the TAP PAP, by the way?

Well, I didn't care so much about the max. It was really just increasing the min and keeping it on APAP, because of those times when I really do need higher pressures. That being said, I also like the concept of keeping the range relatively small. So, ugh, final tweak - I'll make it 10-15. Let's see...

I'll try tonight at min 11 and max 11 and post the results tomorrow.

Thanks so far for the help.

You understand, I'm basically scared to use a straight up fixed pressure setting, one that is lower than where I was actually seeing apnea events in the graphs.

A lot of my apnea events appear to occur where the pressures are much higher than 10 or 11. All things being equal, if we drew a line at 11, I would still be having a crappy sleep. This is why I opted for continuing with APAP therapy... Also, I understand the point of trying to eliminate wide pressu...

OK. Here's what I'll do. I'll increase the base pressure from 9 to 10. And just for kicks, I'll increase the upper limit from 15 to 20 (even though, according to many, it shouldn't make a difference unless I'm hitting my upper boundary).

Thanks so far for all the help.

OK. I didn't actually read Den's response: Notice in the reports that your apnea events are higher when your pressures ramp up and are fewer when your pressures are lower. Switching to straight pressure makes the machine stop responding to snores and flow limitations......which should improve the qu...

Is there any reason why I seem to have more OA's on higher pressures? Could the drastic changes in pressure be causing OA's? All of this seems really quite absurd and non-sensical.

To clarify, yes, A-Flex 1 was what I've been using for a while. The only change now is to change the min and max pressure ranges for auto from 9-15 to 11.

Yeah, was looking at the flex options for CPAP mode and noticed that there was C-Flex and C-Flex+. C-Flex+ appears to be the CPAP-mode equivalent of A-Flex. Lovely.

So based on feedback, it sounds like what I'll try is auto mode fixed at 11, and will stick with A-Flex set at 1.

Thoughts?
