Just got my results from my sleep study and found your really helpful site.  My results seem a bit mixed to me but I don't know what I don't know.  Any info would be MUCH appreciated.  Here goes:

Age: 43 - a few pounds heavy but pretty minor - no medication or other health problems - mainly sleep on my sides and stomach - LOUD snorer

Apnea/hypoapnea index:  8.4 with 1 apnea and 51 hypoapneas

Sleep efficiency:  88.8%  study time was 419 minutes with 372 minutes of total sleep time

Sleep Architecture:
      Stage Awake: 7.7%
      Stage I:         8.7%
      Stage II:      63.4%
      Stage III:      1.7%
      Stage IV:      1.7%
      Stage REM:  24.3%
105 arousals and micro arousals from sleep and 14 awakenings.
Arousal Index: 16.9 events per hour

Baseline oxygen was 95.6% with a low SaO2 of 77.1%

Average heart rate was 56.1 BPM with a minimum heart rate of 46.0 and a maximum of 88.0

0 PLMS

 

Hello Clowntrigger!
Well, overall, looks like a very mild case of sleep apnea, might even be a good surgical candidate to fix your snoring!

Except for that.

That's a stonecrusher.  See if you can find out how many desaturations you had, and what your NREM and REM AHI's were.  Most important REM AHI.  Also supine and non-supine AHI.  Most important supine AHI.  And REM supine AHI if you can, you may not be able to get that without a graph.  If everything is well spread out, and there's only one desaturation, it might have been artifact.  If one of those other AHI parameters turns out to be highly elevated, then you're probably gonna need a plan.  Write back.

Thanks Sleepydave!  I'm going in after the 1st for another study.

Dave? I saw you just helped clowntrigger with his sleep study results, so I trust you have a good idea of how to read the results. Although, I do not have quite all the information I need yet on my study, I do have some information that I do not understand at all thus far. This is all new to me and real recent (last week) to be exact. Can you give me an overall rating of the information that I just provided here? I would appreciate any help you can give me on this subject. I am waiting for my CPAP machine as we speak.

Patient slept a total of 386 minutes with a mild sleep reduction in sleep efficiency. Latency to persistent sleep was shortened at 12.5 minutes. Latency to REM was also on the short side at 84 minutes. Awake time during sleep was mildly increased at 48 minutes. During the night, there was a moderate reduction in delta sleep? A total of 2 apneas with 104 hypopneas were counted. Overall AHI was 17. It did go up to 37 when patient slept on her back. There was some desaturation to as low as 84%. Delta sleep was moderately reduced.

Recommendations: Initiation of CPAP, and avoid sleeping on back and the mandibular advancement device? What is a mandibular advancement device?

Hi CC!
Well, let's take a browse:

Normal sleep latency is about 15 minutes, REM latency is 90 minutes, so those are OK.
Normal sleep efficiency is at least 85% (asleep 85% of the night) but that reduction could just be from sleeping in the lab.
Delta sleep is the most restorative stage of sleep, and can be reduced by interruptions in sleep continuity by stuff like OSA, or simply as a function of age.  Normal is about 20% of the night.
Your AHI puts you in the mild category, but that O2 saturation kinda moves you up into the moderate level.
CPAP, positional sleeping, and the mandibular device are 3 DIFFERENT treatment options.  You don't need all 3 at once.  IF you could only sleep on your side (what was the side AHI anyway?) that might be enough.  Course, there's no guarantee that you could be sure you do that, and that 84% saturation kinda makes this a risky option.
A mandibular device moves your lower jaw forward and theoretically keeps your airway open when you sleep.  You'd need another sleep study to make sure it works properly.
CPAP pretty much is 100% effective, so it's great that you're doing that.
Good luck!!

Dave? Thank you very much for your interpretation of my sleep study results. I realize that I do not have all the information I need yet to really know how to treat myself appropriately, but I just received a call today from my new respiratory therapist whom I will see on Monday, October 17th, so I should know a lot more by then. She is thinking about putting me on a Auto machine for a couple of weeks first to see where things stand with me, then transferring me to another CPAP machine, but I will let you know how I make out with this after this appointment.
