Home sleep study vs hospital sleep study

the breathing doesn't look like REM.

Got an example of documented REM breathing handy? I would sure like to see one and compare it to non REM breathing.

Went to look in Encore2 but it's busted. Obviously from playing with Encore 1.8 for that guy.

Gonna go right to the sledge...

Bummer...get the extra heavy sledge.

If all you need is some wave form graphs from Encore I think I can get one of mine for you and then you wouldn't need Encore.

Easy enough. Somewhere in the 1.8 install the MSSQL Encore2 server got turned off. GTK.

I got nothing, Time to Google Patrick Regina and tonic REM.

Oh man. You know it's time to get a life when you start showing up in Google searches:

Another one at ~03:53. Maybe that's REM sneaking in there, but the breathing doesn't look like REM. Or maybe it's tonic REM.

What is tonic REM?

And one of the links you gave talks about phasic REM? What's that?

And what's the difference between the two?

And what's "normal REM" if there is such a thing?

Also thanks for posting the full PSG look at REM, but for those of us who are mere patients looking at our own CPAP data, the questions are:

Can the breathing pattern give us a good indication of when we're are likely to be in REM?

And for those of us who have a fair amount of documented WASO, how similar is REM breathing to wake breathing or drifting-in-and-out-of-sleep breathing?

...for those of us who are mere patients looking at our own CPAP data...

So you want the Easy Answer to a Complex Question(s) without the benefit of complete data.

No problem! I can do that!

Parasympathetic nervous system activity is increased relative to wake and remains so during both tonic and phasic REM. Sympathetic nervous system activity is slightly reduced during tonic REM so parasympathetic activity predominates during tonic REM. In phasic REM, sympathetic drive is dramatically increased, thus predominating despite the aforementioned increased parasympathetic activity. Consequently, there are similarities and differences between the two.

So all you have to do is collectively look at the night and find the physiological changes and voila! you've got it!

However, it only works on somebody who is normal (anticipating the ensuing question from everybody, the answer is no). Wake and sleep fragmentation can disrupt the REM timer; drugs and alcohol can delay the REM periods; and xPAP intervention can alter the one and only parameter you (mere patients) have to work with.
