Dr changed me from CPAP to Bipap

I’ve been on cpap for 4 years. I noticed last year that I kept waking up with the pressure so high I had to turn my machine off and back on to reset in order to go back to sleep. I obviously missed my 2020 visit due to COVID, and they finally listened to me in May to get an appointment. Everything is delayed so it wasn’t until end of July they sent me for what I thought was another full sleep study, but it was titration. They didn’t titration me on my cpap but rather a bipap, and then switched me to this BIpap nightmare. It’s been a month and I don’t sleep, have had a sinus infection from the pits of hades. I clean my machine religiously and never had one caused by my cpap ever. My events are increased on bipap, and I feel like garbage. Sore throat when I wake up (they adjusted my levels again last week because I was waking up snoring), now I wake up with this scratchy feeling in my throat that goes to my lungs. I’m exhausted, cranky, and feel miserable. They told me they switched me to bipap because I desaturated on the titration to 85%, and I’ve gained weight. Nobody knows if I desat on the cpap. Anyone have any advice?

My Airsense10 was set at Auto 5-16 and my Aircurve10 is set 7-13.

Does anyone have any ideas, suggestions, or questions I could even ask the doctor so I can sleep again? I can’t take much more of this.

Settings are 7 - 13... but in what mode?
What mask?
What are your humidity settings?
