Sleep study report

It will be a few weeks before I meet with my doctor so I was hoping some of you could tell me what these results mean. I am confident that I am in the clear, but just want to be sure. Here are my results:

Results:

The patient was seen in the sleep lab for evaluation for obstructive sleep apnea. The total recording time was 371 minutes with a total sleep time of 302 minutes yielding a normal sleep efficiency of 81.4%. The sleep latency was 63 minutes. Throughout the night, the patient had a total of 15 episodes of arousal yielding an index of 3.0/hour.
On the night of the study, the patient had a total of 1 obstructive apneic episodes, 0 central apneic episodes, 0 mixed episodes and 0 hypopneas. This gives an apnea/hypopnea index (ahi) of 0.2 per hournwith am apnea index of 0.2. The ahi for the supine position was 0.0. The longest respiratory event was 10.0 seconds and was obstructive in nature. The REM AHI was 1.3 per hour. The patient did not snore during the study.
The average oxyhemoglobin saturation was 98% and the lowest was 94%. ECG revealed NSR.

Total recording time 371 minutes. Sleep onset latency 30.5 minutes. Total REM time was 47.5 minutes. Rem sleep equals 15.7%. NEEM stages 1:5.3% 2: 61.3%. 3: 17.7%


Diagnosis: hyper somnolence


Recommendations: follow up with referring physician, educate patient on sleep hygiene measures, ent consult for upper airway evaluation may be of benefit, recommend weight loss reduction program.


Does this sound okay, as far as me definitely not having sleep apnea? I was tested mostly because of morning headaches and allergy related snoring. I never thought I had sleep apnea, but just want some opinions on the report.

Yep, that is what it sounds like to me.

Okay...I just wasn't sure since it said I had an apnea episode. Though if I recall correctly, many people do, it is just if you have several an hour that you should be worried. I also was curious since it said I only had 47 minutes of REM sleep. I just wanted to make sure that was enough to get a good reading. My total sleep time was close to 4it hours.

Anyone can and will have an occasional apnea episode. It is when we have a whole bunch of them that creates the problem. I had 53 and hour in REM sleep. No wonder I never got any REM sleep.
Even when on the machine the generally acceptable AHI is less than 5.

Sleep stage % of normal will vary somewhat with age.
You can read about them here...http://en.wikipedia.org/wiki/Sleep

Your Stage 2 sleep % is a little higher than norm which might mean that you have less chance to get into Stage 3 and 4 and thus decrease that % a bit. So decreased later stages along with decreased REM might indicate less than optimal restorative sleep cycles.

Just because someone doesn't have sleep apnea doesn't mean that their sleep is "perfect" for all the right conditions to come together to get optimal restorative sleep. It just means you have eliminated one possible factor.

Oh, and the sleep tech also said she "wouldn't see me again", so I took that as a good sign, but I guess I am hung up on the 1 episode.

Oh, I know I slept absolutely terribly the night of my study. I normally sleep quite well but did not sleep normally at all.

One apnea episode amounting to 10 seconds barely meets the criteria for diagnosis.
You will need to find another reason to blame your symptoms on because 1 single 10 second episode in REM sleep (you had ample time in REM to have a bunch of others if they were going to happen) isn't enough to come near to causing a problem.

I see you say you slept horribly the night of the sleep study. Probably in the back of your mind you are thinking that maybe you slept horribly and maybe they "missed" something but with 4 hours of sleep and you went through the stages of sleep...they got enough data to know if sleep apnea was the problem.

What do you mean "barely meets the criteria of diagnosis"?

I wasn't diagnosed with osa, was I?

The apnea event itself...barely meets the criteria to be a diagnosed event.

"Apnea is the cessation of airflow for 10 seconds or greater. "
so your 10 second event barely meets criteria to be called an apnea.

Unrelated to your overall diagnosis. I was just referring to the criteria for the apnea event needed to be met to be considered satisfying diagnostic criteria.

You didn't have enough of the "diagnostic" events to warrant the diagnosis of OSA.
