New Sleep study - lots of questions

Got a copy of my initial sleep study and I don't have a clue - but a lot of questions!

I don't know what's important, but I will post some info that looks like it might be helpful.

Sleep architecture - efficiency 94.8%, arousal index 47.0 (I'm assuming efficiency is good - but what about arousal?)

TST 491.8; Sleep latency - 2.2 minutes?; 28.2 REM sleep. REM sleep latency 103.0 minutes. 4.1% of Stage 1 sleep, 43.0% Stage 2, 24.8% Slow Wave Sleep.

Respiratory - 423 respiratory events - 3 Obstructive Apnea; 73 Hypopneas; 0 mixed; 8 Central; 339 RERAs (What does it mean to have Central apneas - even if it's just 8? Also, is there anything differently that should be done when there are so many RERA's?)

AHI - 10.2
RDI - 51.6 (High?)

Respiratory arousal 45.6 (Is this high and what is the significance?)

Oximetry - Lowest saturation 87.0; 1.4 minutes below 90%

Alpha intrusions were seen. Especially evident during slow wave sleep as "alpha-delta patterns." What is this?

Parasomnias noted during REM sleep, consistent with RSBD.

Sleep study doesn't offer much in explanation other than OSA.

Would appreciate any input!

You have mild sleep apnea, but you have a lot of breathing pauses that don't meet the criteria to be "scored" as apneas (a complete cessation of airflow to the lungs) or hypopneas (partial cessation of airflow to the lungs). However, they are significant, and occurring more than 50 times an hour.

There's no difference in treatment for RERAS, hypopneas and apneas. The gold standard treatment is CPAP.

Interestingly you also look like you may have REM behavior disorder.

When do you follow up with your doctor to go over this all properly?

Alpha intrusions are usually caused by being on medication. Medications for depression are usually a big culprit. Not a bad thing, it can just make the brain waves difficult to analyse.

I don't have sleep apnea or any other sleep disorder but I did have alpha intrusion. Just makes it a little harder to interpret the waves :~)

(Sorry to put this in several posts. I'm on my phone and it's playing up)

Did you use a cpap during this sleep study?

This was just my initial sleep study. I don't have the titration study yet.

I do know I have RSBD. I've run into walls and knocked off everything off of my night stand several times!

I don't take any depression medication. But the report said that chronic pain syndromes & fibromyalgia have been associated with the alpha-delta pattern intrusions. I have both so that makes some sense.

Does anyone know what are the normal rates for RDI & Respiratory Arousal Index are?

Yes chronic pain is definitely associated with alpha delta intrusion.

Your arousal index is 47 an hour. This means your brain is "waking up" 47 times an hour.

It's normal for it to wake up during the night (without you knowing) but when your sleep apnea is controlled this number should drop to much lower (<20 per hour)

Keep us updated how you're going. In a sense it's great that you now have a diagnosis of REM behavior disorder, because now something can be done about it!

Confused....You joined this forum in 2006 and you just had your initial sleep study? What's been going on for the past 7 years?
Reading your old messages indicate that you had a previous study.

Yes, I have been diagnosed with Sleep Apnea, but decided to have surgery instead of CPAP. It's been so long, that I don't remember much about my previous sleep study. I had had a very low oxygen level (67) previously and pulse of 28. So that part seems better. But obviously I still have sleep apnea. Don't understand the Central Apnea, that's new. At what point would one be on a BiPap for that?

And I don't know what numbers are high and low. the RDI and RAI seem like they might be high and it does seem like a lot of RERA's as well as Hypopneas added in.

I know that 67 was low for oxygen. Is 87.0 for lowest okay? 1.4 minutes under 90?

Never heard of Alpha Intrusions, but interesting that might be cause of the Fibro and chronic pain I have. Does it make a difference though? Anything that can be done about it?

My mother has Alzheimer's and I have inherited her gene. Recent testing shows I have Mild Cognitive Impairment. I want to make sure I do everything to maintain a healthy brain, so I am committed to wearing the CPAP at this stage.
