Hi allielb83, welcome to the forum!
Here is an article which includes discussion of RERAs (Respiratory Effort Related Arousals) and suggests bi-level treatment can often improve sleep quality beyond that achievable by common CPAP therapy.
However, in your case about half of your AHI is made up of Central Apnea events, and I think standard bi-level therapy tends make CA events more frequent.
CA events usually resolve themselves during the first several months of PAP therapy, decreasing on their own to just a few per hour or less.
If you eventually try bi-level therapy to see if it will improve your sleep quality, after 6 months if the CA events have not decreased to a few per hour or less, there are types of bi-level therapy which can handle both OA and CA events. One is called Adaptive Servo Ventilation (ASV) therapy, but new ASV machines are nearly $2K from Supplier #2
, and I think some insurance programs will not cover ASV machines unless the majority of the events making up the AHI (Apnea Hypopnea Index, average number of events per hour) are Central Apnea events, AND the CA Index (all by itself) is at least 5 per hour (or with some insurance programs, at least 15 per hour). So perhaps one may need to pay for that type of machine out-of-pocket.
