Banning from Apneaboard can be temporary as a warning, but maybe you were permanently banned. Please read the rules section if you can re-enter.

You've got to be fucking kidding me.

They ban innocent posters just because they think it's me!!

I do not have an Albercook favor asked of me.

Let me refresh your memory:
Thanks for nuthin'!!

Where are you living now? Did you spend time in the flatlands then go back to 8000 feet?

Does anyone know why some have such a breath wave shape?

Yes.

Using APAP not BiLevel so what do you think causes the steep to a point waves?

Did you do that favor about Albercook that I asked you to do for me?

I heard it can be reprogrammed. Does anyone know how to do it?

Easy!

Yes.

...when the OP starts inhalation, there isn't smooth acceleration at the outset; instead there's a pointy bump or lump. Oh right! I should have paid attention to your original point: One is that many of your inhalation curves have a more pointed shape than we usually see. Anyway that's probably BiP...

I'd love to learn why the "bump" in the first part of inhalation is part of the "expiratory limb." It's not the first part of inhalation-- it's the last part of exhalation. Inspiratory phase is only when there is actual inspiration. Expiratory phase is everything else. expiratory-flow-pattern-n.jpg

On CPAP in an in-lab sleep test I was having 11-12 non-movement arousals per sleep cycle, so apparently that's enough for my sleep quality to tank. Arousals/sleep cycle is not what you'd call a "traditional parameter", but if a sleep cycle is ~90 minutes, then the arousal index would be ~8.0. Would...

there does appear to be a very slight decrease in the presence of naps

And even that doesn't look like it's going to be sustained.

... the data... When I switched from CPAP to BIPAP I felt 10x better and had deeper more restful sleep. Well, looking at "the data": semb.jpg there does appear to be a very slight decrease in the presence of naps, so I'd say maybe 0.3x better. However, what jumps out is the amount of "sleep" (and I...

...the bumps or lumps in the inhalation trace.

That's actually part of the expiratory limb, so IMO probably cardioballistic artifact.

...should I just keep cranking it up?

Based on the data presented, you don't even need BiPAP, much less more pressure.

Or is it something else?

It's something else.

Inspiration is only that part of the waveform above the -0- line.
