OSCAR for me has been a very useful thing especially when the time in synched with my fitness tracker. It allows one to see if changes they make to their routine help or not. It takes a bit to understand the graphs and the event types, but it's worth the time.

I found that my sleep events are terrible when sleeping on my back and good when on my side. Like night and day. A soft collar didn't help with my chin-tucking, although it does for many.

Also when I get a cluster of obstructive apnea events, it usually wakes me up - as in a "get out of bed, make a stop in the bathroom and go back to bed" awake.

Also found few to no large leaks, but several non-large leaks which adjusting the mask a bit tighter helped.

Sleep med had bumped my pressure from 8 to 9, then 9 to 10, which didn't help much if at all, so I'm seeking a bump up to 11. Doc wants me to sleep on my back, but pain forces changing to my side, then changing to the other side and back to the back. - then repeat. It's a bit similar to sleeping on a rotisserie!

I was kidding with my sleep med doc about having a "million dollar idea" of building an AI app to analyze the plethora of CPAP data and make a recommendation.
