I finally did a home sleep study from my dentist's office using my oral appliance. On my new Resmed machine, my AHIs are about 1 or something.

What I'm wondering is if this is good enough to just use for travel and stuffy-nose nights, or if they're good enough to use it more often. I am seeing the dentist this week and can also have it adjusted more as it is still comfortable. I had eye surgery a short time before this, so I may have slept on my back a little more than usual so as to not disturb sensitive parts of eye. I may have him tighten it up and test again.

What do you think?

Overall AHI: 7
Overall RDI: 14
% time <90% SpO2: 2.2%
Mean SpO2: 94.3%
% time snoring > 30db: 29.7% (So, they weren't all lying!)

More from the narrative: slept 5.1 hours with a sleep latency of 9 minutes and a sleep efficiency of 86.1% Mild disordered breathing is noted based on a 4% hypopnea desaturation criteria. Slept supine 17.4% of the night based on valid measures of sleep disordered breathing, the overall respiratory disturbance index is also mild (RDI=14) based on a 1% hypopnea desaturation criteria with confirmation by surrogate arousal indicators, predominantly in the supine position (19events/hour). The apneas/hypopneas are accompanied by minimal oxygen desaturation. The average across all sleep disordered breathing is 2.8%. 14.5% of the snoring is very loud. Mean pulse rate is 80.

The patient should avoid sleeping supine. The non-supine RDI is 1.5 times less severe than the supine RDI.

I wish I had been awake for the surrogate arousal events, whatever the hell those are! :-)

From the report, it sounds like it would be okay if you were to stay on your side.

I think how much you use it depends on how rested you feel and/or your tolerance level. For stuffy nose nights some people just use a full face mask. Or they get a travel CPAP. (basically they'll do anything to use their CPAP.) The only way to really see how it works for you it by trial and error.

To me though, the statistics (RDI) is still quite a few unnatural awakenings per night.

:lol: Those are just markers that are used when there is no EEG. With EEG it's obvious when you wake up. It's a direct measurement. Surrogate arousal events are things like increase in heartrate, one or two louder snores than the baseline, and in increase in respiratory all at the same time. Usually with a HST, these are pretty weak. In the lab these would be things like a leg movement, chin tension increase, etc. HST's don't have those.

Thank you! I just figured out what "RDI" is. I guess that means 14 disturbances per hour, on average.

The dentist tightened the device at my request and encouraged me to use it occasionally for the next several weeks and then we'll do another test. As I mentioned, I was recovering from an eye surgery and probably avoided side-sleeping a little to protect my eyes. I think the next test after the adjustment and no eye issues will be more telling and hopefully better.

I feel okay after I use it. It's a little bit of a tradeoff with the CPAP. I think the CPAP works better....in fact, I know it does from the statistics. I'm aware of both of them during the night. Perhaps the oral appliance a little less which makes it feel almost even.

Yes, exactly. But it does have to be Respiratory related. Respiratory Disturbance Index.

Spontaneous arousals wouldn't count.

That's good the oral appliance doesn't bother you that much. Some people start to report problems with their Temporal Mandibular Joint and start getting headaches because of it...especially true if it's over-tightened.

I got terrible jaw pain after about a month of this device. I also got reflux one night and couldn't get the device off. Horrible.

After trying some of the alternative treatment options, many people decide that CPAP isn't so bad after all. :)

I had my oral appliance tightened somewhat, although the dentist is conservative, and then I had an in-lab sleep study that was split with half the night my oral appliance and the other half my CPAP.

With the oral appliance for 3 hours, my AHI=1.4 and my RDI=5.6 which is considerable better than before. It is with the caveat that was all side-sleeping and not a lot of REM. But, it's good enough for what I need to use it for.

What does the dentist's political affiliation have to do with it? :lol: Just kidding!

Too bad there wasn't REM sleep. That's very often when the wheels fall off with sleep disordered breathing.

How did the oral appliance numbers compare to the Oral Appliance segment of the recording?
