Of course!

I hate charts and squgglies.

But when it comes to NPSGs and evaluation of sleep cycles and stages, the first few pages of this chapter seem to give a nice overview, I think:

A Graphic Representation of Sleep Stage Percentages:

Again, since this is a "basics" thread, including ("Sleep Study") after the initials NPSG would make the meaning of the topic more obvious to true n00bs. Although this thread is less about the study itself and more about sleep architecture.

Thanks for this explanation, mollete! I have recently been doing a lot of reading on this. I want to learn more about the effects of deprivation of different types of sleep. It appears that deprivation of N3/4 brings about different symptoms than deprivation of REM sleep. Not all sufferers of sleep apnea have the same type of sleep deprivation and may experience different symptoms. For instance, in my case, I have a lack of REM sleep but increased N3 (deep) sleep. I score only average to low and even 0 at times on the Epworth Scale, (it varies wildly for me) but I have many symptoms relating to response to stress, ability to focus, memory, etc. One study even showed increased alertness and CNS irritability in people deprived of REM sleep. Someone who has N3 deprivation will likely score much higher on the Epworth scale, but if they are lucky enough to have less deprivation of REM sleep, they may not display the other symptoms I described. Deprivation of overall sleep hours will bring on drastically different symptoms that deprivation of any one type of sleep. I found these interesting studies/ articles that I am learning much from and I'll be happy to add more as I come across them:

"The Effects of Dream (Stage REM) Deprivation on Adaptation to Stress"
http://www.psychosomaticmedicine.org/co ... 7.full.pdf

"The Effects of REM Sleep Deprivation on the Level of Sleepiness/Alertness"
http://www.journalsleep.org/Articles/210607.pdf

"Sleep Deprivation" (A web page from Macalester College dedicated to the topic - scroll to bottom for outline)

"Dreams: Night School"

Blessings,

"IMHO", the 2008 or 2012 "Da Rules" book should have allowed an amplitude "handicap" for age, or perhaps a NREM2△ stage (low frequency NREM2) to account for this phenomenon, and give credit where credit is due.

This "older person" thinks so, too. Thanks!

Yes, I'm still ignoring my PLMD and still feeling completely rested on CPAP.

Oh, and a few months ago, I switched (completely and forever) from smoking to vaping. I know, I know... but hey, of the two....

Congrats! I did the same after I was hospitalized with pneumonia in early February. I tried to not do it, but after 37 years of smoking... well. You know. I find the vaping helps a lot and I have no desire to smoke. I did try smoking once when I left my e-cig home. The cigarette tasted terrible and actually hurt to inhale (thank you, Lord-- if it hadn't, I might not be an ex-smoker!) I find I don't even use the tobacco flavored carts any longer. I use the V2 and like the menthol, cherry and especially the mint green tea. My pulmonologist at the time said "I'd rather you not, but if the alternative is that you start smoking again, then go right ahead and use the e-cigs."

Blessings!
Kate

EDITED: Ooops.. we took the OT V-Cig convo here: Sorry!

WTG, Kate.

The V2 is a convenient size e-cig, from what I've read on the ECF.

Here are the two I use:

Hope all goes well for you, Kate.
