yep. your pressure is low so I would not expect it to be causing your centrals. You need to look into ASV machines, they are the ONLY ones that treat true centrals (not CPAP induced ones)
The headaches in the morning are from retained CO2 or so my doctor said. Mine tweaked my settings and no more headaches.
Thanks... will make another call tomorrow.
My buddy is going through the same problem. He started off with CPAP, and he began to have frightening episodes where he would awaken choking and gasping for air. He was actually afraid to use the machine at all. His sleep doc told him that he has complex apnea and needs an ASV machine. Apparently the use of the CPAP machine brings out centrals that were absent without the therapy.
Interesting... the thing about my centrals... they were never absent. I've always had them, they just don't happen all the time. The past few weeks I've been having them. Tomorrow it might stop and I'll go back to an AHI of < 2 for a few weeks.
The fact that your central apneas are intermittent might suggest there is an environmental or behavioural factor contributing. For example, do you travel a lot, have occasional very late nights, work shifts, have occasional exposure to chemicals or other environmental changes, use alcohol or other drugs on occasion? Do you have other health issues which may be periodic in nature?
The reason for these questions is that I don't think it's normal to have severe central apnea on occasions, then none for weeks. There may be a factor which is triggering them. If here is such a factor and we can isolate it, then you could work to eliminate it. Or alternatively, you could try and time the exposure to suit your next sleep test.
In any event, an autoset is probably not doing you much good at the moment. It can actually aggravate your central apnea, which is obviously counter-productive. A well set-up ASV machine will eliminate central apneas and generally control obstructive events as well. If there is no environmental factor to eliminate then I see an ASV in your future. Unfortunately these are expensive and the "system" will make you jump through hoops to get one.
