REM in sleep lab

First Question:
Is having apnea or hyponea in REM in the first half of a split study the only way to determine if I have OSA? I was told I didn't have any events in the first half of my sleep study and no REM either while sleeping on my side. I had REM in the second half with some events (while sleeping supine) but because it was the second half I was not titrated. Will ask my Dr for a copy of the hospital study results. I want to educate myself before I read it to understand it better.

2nd Question:
I am registered, but when I start a new topic the board says:" The username you entered is already in use, please select an alternative." That's me! Where do I go in here...or how do I properly use this forum. It took me to a lot of dead ends before I found how to enter my equipment info. Now I cannot find that page
Thank you for your help!

No. The actual definition of OSA does not depend upon REM, nor does diagnosis require that you have events during any particular period of the night.

That is because you are not logged in. When you are logged in, you will not have a place to put the username when you start a new topic. You need to login. Look up in the upper right-hand corner of most any page to find the little word "Login". Click there and you will have a screen where you can fill in your username and password. The "keep me logged in" option is meaningless with some browsers.

Login first, then in the top left-hand corner of most any page click on the little phrase "User Control Panel". From there you should be able to edit your profile again.

Did they tell you your events were not enough to merit a titration on another night, or are they going to schedule you for one? Not being diagnosed during the first half of the night doesn't mean you don't have it, just that it didn't show up during that time frame. So many reasons in a sleep lab to not be able to sleep much. Whether your study was enough to adequately determine if you need treatment depends on how much sleep, how much in REM, and how much supine in REM they were able to capture. When you get more specific info, let us know.

First...Thanks for your answers. Much appreciated. And finally discovered how to log in. I just didn't look far enough to the right (small monitor?) More likely some brain fog in action.
In my split study it felt like I slept for 7 hours but Dr. told me study reported I slept only 50% of the time. Loud talking right outside the door woke me up and that went on and on. I laid there, gosh, I don't know how long as there wasn't a clock. When I finally pushed the button for the tech it was 3:30am. I asked her when would I begin titration and she said I didn't have enough events to do it.
You can bet I wasn't happy as the first home study indicated an AHI of 27 and O2 of 83%. The Dr gave me his report and suggested my apnea was positional. He told me I could use a tennis ball in my sleep shirt. I tried it and still got up each morning with a sore throat and reports from my husband of excessive and very loud snoring. Also, I get muscle cramps and enough hip soreness to make me limp around before my shower. I requested a second home study as a tie breaker. It came in with AHI= 13, 127 Hyponeas and an O2 of 84%.
Thanks again,
Cindy

It is possible to make a diagnosis with just a tiny bit of sleep.. all that is needed are events...

if you have enough, even in a half hour period, you would probably be sent home with an auto machine for a week to do an at home
titration...

I happen to have events the very first minute i fall asleep, so they were able to diagnose me, but not titrate me..


they should be able to diagnose you.. and if you are having apneas and cant stay in one position (who can really) you need to be treated..
