Also attaching my sleep study info that I did in January when my exhaustion was worse. It was an in-home study (just had a couple of thin hose prongs in my nose and a pulse-ox monitor) and if I'm reading this correctly, shows almost no CAs or OAs. It put my AHI at 8.5 My first night with my CPAP 5 weeks ago showed an AHI of 13 with 43 CAs, 47 HYP, and only 4 OAs. The different types have swapped places all the time over the last month.
I don't have any info on titration of my machine. I just bought it and started studying up and doing my best.
My current plan is to try to keep my ahi around 2 or lower for a couple of weeks and if there's no improvement I'll go see the cardiologist. I'm very fit and my resting pulse is around 60 and my blood pressure is good and my basic blood work was all normal.
