If you do not get much of a relpy try the following forum:
It is a very good forum dedicated to CPAP users. and has helped me a lot.
personally it took me about 9 months of struggle to defeat centrals. I basically had to try cpap and fail, bipat and fail. (part of the problem was that most of my centrals were late in the sleep cycle. the sleep studies always woke me up early.) Anyhow I got a home sleep study that verified the centrals that the RESMED cpap and bipap were recording but could do nothing about…
Both CPAP and BIPAP can keep an airway open, but they can not breath for you.
Anyhow after there was an official study that showed the centrals, I was finally prescribed an ASV auto (Auto Servo Ventilator.) This machine actually breathes for you when you do not. (during a central)
My AHI on cpap and bipap only got down to 10 and 95% of them were centrals.
On the ASV my AHI is 0.0 most of the time. Past month my AHI was 0.45 (which was 5 events over a 10 hour noght). My average for the month is 0.14 according to sleepy head…. That is less than 2 events per night…..
So….. try cpaptalk.com.
But I would try to get an ASV machine prescribed first….. It has done wonders for me.
