What do you think?

I finally received the raw data from my sleep study in May 2009. I've found something that are somewhat concerning. Here is some of the info:

Stage 1 sleep: 41.5 min
Stage 2 sleep: 266.5 min
Stage 3 sleep: 0 min
Stage 4 sleep: 0 min
REM sleep: 33.0 min

Apneas were average of 19 sec with max of 33 sec.
Hyponeas were average of 34 sex with max of 52 sec.

My SAO2 nadir in NREM was 81 and in REM was 91. I did actually fall to less that 60% in NREM for 12 minutes (?).

If there any wonder I don't feel rested in the morning?

Hi tvmangum

I read your post, but am unsure of what you are concerned about.

You have your machine, and presumably you are using it. You say you are not feeling rested in the morning, but the data you posted is from your sleep study. You imply that the sleep study results are connected to your not feeling rested in the morning, but I cannot see the connection.

So if you could be more specific please, about what is concerning you. Is it something about the sleep study, or is it something about your present situation.

cheers

Hi. Yeah, once I got my sleep study results much after the fact I got a glimpse of just why I had felt so bad. I still feel bad, but I know my sleep is still fragmented due to limb movements. If you are feeling bad still, have you done anything yet to pinpoint if it is OSA related or otherwise? How does your data look, including your leaks? If your treatment is therapeutic, those scary oxygen numbers seen in the diagnostic study should be resolved, unless there is something else going on with you. If you are concerned about that, you could ask your doc to order an overnite home monitoring of your oxygen levels. Best wishes as you seek to determine the source of your continued sense of not being rested in the mornings.

My only confusion (my numbers were similar) is that you actually had REM sleep. I thought Stage 3/4 was required prior to entry into REM sleep? I had 0 min REM sleep during my study.

My o2 sat was 78, but I don't know if that was before or after they administered O2 (1 liter) during the night

PS: you had "sex" 34 times so it can't have been all bad

The sleep stages is confusing. As I posted last week on sleep stages, the "book" (doctors, scientists,etc) give numbers of how long each sleep stage should last, how many times you cycle through them, etc. In the lab I get to see numerous patients come through that don't even come close to the "book" rules. Some people do skip stage 3 ( there is no longer a stage 4) and enter REM. This could also possibly be an error on who ever scored the study. They may have missed some stage 3 and counted it as 2 or REM, not sure. Just a side note did you know that when infants fall asleep they go immediately into REM ( called quite sleep) then into NREM sleep (called active sleep) then back to REM. Too bad we can't continue that path as adults~~

Montana User, I also understand from my reading (not just the internet, but various scholarly articles) that patients who are sleep deprived can often skip deep sleep. My current neurologist / sleep specialist noted that it can take quite some time after good compliance and effective therapy before the body starts to return to "normal" (whatever that is) sleep architecture. I personally know that's true for me. I still struggle to sleep more than six hours a night. However, that's up from three hours when I started using my ASV unit. I was so sleep deprived when I received my unit that if I closed my eyes I would start to dream. (Talk about short REM latency!)

So for the original poster, it might just mean that his body shifted him to REM sleep after Stage 2. Or, as you note, someone might have scored it incorrectly.

Hilarious!

sex with 34 - quite an orge for a sleep study

You are absolutely correct JohnB... you can skip deeper sleep and hit REM. In fact we see what we call REM rebound in the lab during a first time CPAP titration. These are the people who do not get REM/deep sleep very often and will spend the better half of the night in REM. It is just amazing to watch so much REM in a person. When I worked in the 6 bed lab we would call it- REM Marathon, and we would see which Pt. would come out of REM first.( yes we would get bored sometimes) Some patients just had allot of deep sleep to make up for.
