Anyone good at reading OSCAR data?

Hello, just wondering if anyone is good at reading OSCAR data and giving suggestions?

I've struggled to use my cpap machine ever since I got it many years ago. But I always try to use it every now and then to see if anything changes.

I used it for about 4 nights and each morning I will wake up with a stomach full of air, which is a common occurrence whenever I use the machine.

I also noticed that most of my AHI is made up of clear airway events, any ideas on why that might be?

Thank you!
