sleep stages-sleep study

hello all, Was thinking my sleep stages are not great ,in pre-cpap or optimal(on cpap) in my sleep study report.
stages n1, n2, n3/4, r (rem),

pre cpap 24.2% 75.8% 0 % 0%
cpap(optimal) 2% 39.6% 4.7% 53.7%

the report says my ahi went from 68 to ahi 0 ,which I'm loving but am concerned of the low percentage of stage3 or 4 sleep. I am in my forties , no meds, with a pressure of 8 prescibed. so far my numbers on cpap are around ahi2.0 ah .6 hi 1.4 leak .00 on a good night. So dont want to change any settings now.
Should I worry about the stages of sleep on and off cpap during the sleep study or just wait a year or so and find out what the next sleep study says? thanks for any insight.

I'm no physician, or anything professional in sleep medicine - so I may be wrong. Your sleep architecture looks to me like what they call "REM rebound". When cpap therapy reaches optimal pressure (and your's sure does) and you are no longer snapped out of REM by choking, the brain suddenly -- and temporarily spends a disproprtionate amount of time in REM - that's normal, and settles down after a few days. I don't know what REM rebound looks like numerically, but this sure fits the description.

thanks Ozij, Was hoping this was a short lived event ( lots of rem sleep with low 3 or4 level sleep). Besides a sleep study just don't know how you would figure out which stages of sleep you're in down the road on cpap.I seem to feel better so maybe it doesn't matter much.My doctor who sent me to the study is not really a sleep doctor so im seeking answers from the much more knowledgeable here.

I'm not one of the more knowledgeable here about cpap, but I have read a good deal about sleep architechture (and I stayed at a Holiday Inn Express last night). Normal time spent in stages 3/4 for adults (25-55ish, but not older) averages about 15% and will range around a bit on that average person from night to night maybe between 10%-20%. But it definitely would be crazy to expect the cpap titration night to be normal. It is part of a transitional period, not the new baseline. I wouldn't worry about it.

I'm with the previous 2 posters. I don't see anything there to worry about. Your body is doing exactly what it needs to do to recover.

Thanks brain_cloud and millich, the worry is subsiding for sure, and it is better to be crazy than injured without a cure.
