REM SLEEP - Home Detection
Sorry about the link, not used to that.

Yeah, I'm no stranger to the math and I'm not sure how deep I should dive into this one myself.

My son thinks that the 5 channel may not be enough to determine REM, but may need 14 or a full 24 like they use in a sleep center.
These were the most advanced off the shelf ones I could find for single purchase and would need to be adapted.
Their setup and software is for a different purpose.
If we could make it work, I had some ideas for gear to help apnea tinkerers like are here.

Tough project though and if it requires 24 channels, it would be so expensive might as well just buy a used one from
a medical supply outfit.

If it doesn't work I am sure we will have fun playing all the way.

too many variables, the site on which i found the math, they were analyzing the data to control air conditioning, lighting, noise etc. to improve the quality of an individual's sleep.  if it would improve my sleep as well as xpap, I might buy the thing, probably have to trade my car to afford it

What a cool idea - even if speculative.

reading articles about REM sleep, such as http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3199805/  and http://jap.physiology.org/content/83/6/1923 (on respiration and phasic REM sleep) will give you a start for what kind of indications you may have from sleepyhead data that you are in REM sleep.

Awake breathing usually looks different than asleep breathing in both normal and apnea subjects.  REM breathing looks a bit like awake, but some interesting aspects generally give it away.  Transition from sleep to awake usually increases Tidal Volume.  Transition from {non-REM} sleep to REM sleep usually shows as a mild decrease in Tidal Volume.  In REM sleep Respiration Rate generally varies widely with less control, like a regulating mechanism has slowed or is not bothering.

You may dream only during REM, or maybe during other sleep stages.  review post http://www.apneaboard.com/forums/Thread-...#pid125322 and http://www.apneaboard.com/forums/Thread-...#pid121660.

happy searching.

by the way, I had a plan to get EMOTIV device and just haven't yet.  Maybe someday.

Dedicated to QALity sleep.
