Sleep onset breathing issues

Hey guys, i'm Stephenie.
I'm new here but have been lurking for a couple months.
I have OSA and have been faithfully using Resmed 10 Auto Pap since the end of June (before that, I was using the Dreamstation from December-to June) so I've essentially been treating my apnea for about 9 months. The past few weeks i've been noticing a new issue that I used to have when I didn't have my cpap and was just not treating my apnea. It didn't happen all of the time, but it was really frightening when it did and now lately it's happening again. Whenever I drift off to sleep, I notice I feel like I'm holding my breath and my ears will whoosh with pressure like when you're in the pool and really need to come up for air. That's how it feels. But i'm wearing my mask when this is happening, and it ONLY happens when i'm falling asleep. After I can actually get to sleep I never have any (known) issues with this feeling the rest of the night. It happened really bad on August 30th. I will attach photos of Oscar data in here) and it happened again today. When it happened on August 30th, I woke up and saw my oxygen was 80! I completely panicked thinking I had some kind of lung disease because why would my oxygen drop so low if I had my mask on? I messaged my pulmonologist/sleep dr, and he told me we would schedule and oxygen/titration sleep study so he can see what's going on. When it happened today I made sure after the first time I had that holding my breath feeling to put my pulse ox on and leave it on (just a regular Walgreens one, not the recording one) and when I'd wake up my oxygen would be fine. It was 99-98. so the issue with the dropping oxygen I had on the 30th didn't happen again with this but it was still the same sensation. Any ideas on what's going on? I don't have any history of COPD (never smoked) and my oxygen during the day is usually 96-99. It doesn't help I have severe health anxiety that is fueling my fear of going to sleep in fear that it will happen again. Thank you in advance. The two images is when it happened on the 30th (double check me but it looks like I stopped breathing for almost a minute at one point) and the the other image is today.

And last one

It would be a good idea to post the graphs as laid out in Oscar - you've skipped important ones and added those we don't need to look at.

I’m not sure how

You also need to learn how to zoom in and look at the flow rate (each individual breath) at the time you are experiencing whatever problem you seem to be having.

You might want to consider getting a pulse oximeter that records all night and is compatible with OSCAR. Spot checking isn't very reliable.

And as Julie said...re do your posted details in the generally accepted basic format. We have to start with basics first,
Nothing you posted is particularly useful.
Read this thread for examples

So the basics and then zoomed in flow rate at the time in question in about a 2 or 3 minute segment.

Is this better
