Hey there,
So i recently had a consultation with a professionally trained sleep study expert. It's $400 and he does it over zoom. He looks at your Oscar data and then teaches you how to read the data, and then goes on to provide recommendations, and we'll meet you several times until you have good results. He also has a YouTube channel.
What I learn from him was pretty remarkable. First of all he completely disregards everything on the left side in the panel. That's because that is not Oscar data, but rezma data and the algorithm is highly unreliable. He demonstrated by going through my waveform data how there were numerous incorrectly marked hypopneas, apnea's, flow limits, and even more missed events throughout the night.
He actually taught me how to look at the waveform and how I thought seemingly normal or good waveform patterns were actually bad. As an example a night where my ahi was less than 1 and I did not have a massive amount of flow limits, actually contained at least a dozen hypopneas within a 1 or 2 hour time frame, all missed. Turns out my pressure settings and my approach to leak were completely way off despite all the advice.
This form has taught me a lot, but it shouldn't be your last stop. In your case, kind of like mine, a lot of independent fix-it was tried but yielded subpar results, working with an expert can help a lot. And compared to the cost of other options you're thinking this is substantially cheaper. Also even after surgery or dental appliances, using CPAP in conjunction is still not a bad idea.
Here's the guy
