9 Central apneas??????
I recently had a sleep study and had 9 central apneas.....had 64 obstructive trype....is that something that should concern me? My O2 dropped to 79% at one point. I am getting a CPAP but someone told me I should be most concerned about the central apneas.

Depends upon when the centrals happened. Many experience centrals upon going to sleep. I would suggest talking with your doctor and seeing when they happened. Were they in a cluster? Over a period of all night? In talking to your doctor try to pinpoint the cause. Without knowing more info it makes it hard to advise you.
Hopefully one of the sleep techs can give you more guidance.

No one has really explained anything to me. I am in the military and was referred off base for the study. Upon completion of the study I walked out and no one explained a thing. Results were sent to the military and it took call after call to get someone to speak to me about it. So I can't answer any of the questions you posed about the time frame of the apneas. I spent the night and had 9 central and 64 obstructive. Of the 9 centrals they were all NREM and mean duration was 18 and range duration was 16-21. I don't know much other than that. Also I've decided to attach the study. I am being fitted for the CPAP in a couple of days, perhaps things will be explained to me then. Which leads to another question...will I walk out with a CPAP that day or what? I am so confused. Sucks I have to rely on messages boards for education.

Sorry Charles I am not familiar with the way the military does their "thing".
Ask for a copy of your script, a hard copy in hand. Hopefully you will be given a data capable machine, better still if it is an apap that is fully data capable. Just because it has a 'smart' card doesn't mean that it provides detailed data. I would say, again remember I don't work in the sleep field, that you are in the mild or moderate range of sleep apnea. Severe sleep apnea is having over 30 events per hour. Do you know about how long you slept?
Did they use a cpap on you during the sleep study? If not then you will be given an apap to titerate your pressure.

No CPAP was used for the initial study my AHI was 14.1 I slept a total of 315 minutes....sleep effeciency was 79.2%. I am having the titration done on the 10th.

Okay then you are scheduled for a titration study on May 10. Chances are you won't get your cpap that day, at least that is how it works in the civilian world.
Your pressure requirements have nothing to do with the severity of your sleep apnea. Someone with mild sleep apnea may need a greater pressure than someone with severe sleep apnea. "Typical" pressure requirements are usually around 10, but that is a rule of thumb and depending upon whose thumb you are measuring by. :) During the titration study they will start you off on a low pressure and slowly increase it where you are no longer having apneas. Your pressure needs depends upon how much is needed to keep your airway open. The pressure splints your airway open so that it doesn't collapse, the cause of obstructive sleep apnea. If the doctor deems your centrals of to be of concern, then that will be addressed and may depend upon which machine you get. Centrals typically do not respond to straight cpap since the cause is different. Centrals are where the brain doesn't send the signal for you to breath. I am not that familiar with centrals and so can't be of much help there.

Hey Charles,
First off, Thank you for serving!!! Secondly, I'm not a MD. If I had to tag a worry lable on those 3 items you mentioned (9 centrals-64 obstructive events-desats to 79%) for a family member of mine...not knowing the lab/center you went to, I would be more inclined to worry about the 64 obstructive events first...which very likely led to the the desats (which I would move to worry #2), the centrals I would put in last place. There are some sleep labs/centers out there that will call a resp events after an arousal a central, and some don't. When studing pts, when they have a resp event I will most likely never call the pause in there breathing which occurs afterwards a central. Personally think you should snag a copy of your sleep report and go to your base clinic/sick call and ask to speak with your MOD or Flight Surgeon.
In regards to your cpap...really don't know if you'll walk out with a machine that day. Some do, some don't. If you don't, you should get one within 5-10 days (again should...that might be off).
I know it's a bear not to get the answers you are looking for from your docs...but there are a lot of helpful folks here and other sites, so if you have ?s/concerns KEEP ASKING. Let us know how's it going.
Walt
