I need to make a correction. I was tested with the machine I had, a Bipap, which made me feel worse. I didn't realize a bipap is just an adjustable cpap. So you know, both bipap and cpap can worsen central apnea. I still was not able to tolerate a vpap.
If you are not feeling improvement with the cpap, talk to your doctor.
I will be keeping up the Maya. Take care.
