Hey Sammy,
It seems strange to me that if your tech doing the titration started to see Central events and stoped going up on the pressure, then why did your Doc then order an increased pressure above where the Tech stopped. Were you still having obstructive events? Do you know what pressure the Tech maxed out at? What is you machine set at now, 11cm?
When I am doing a titration and start to see central events I stop and ask my self questions. The first question is if I am still seeing any Obstructive events. If the answer is no, then I will drop the pressure back down to a level below where the central events started. Perhaps I went too high too fast and my patient was not ready for the increased pressure? Most of my patients will start having central events if I get the pressure too high. (I tend to get you where I think you are good, and then go up some more to see if you can tolerate a higher pressure. My job is to gather as much data for my Doctor as I can and being able to show how much pressure you can tolerate gives him the ability to adjust your pressure with out having to do a new study. If you go home and start to snore again in a month he can look and see how you did a higher pressure and then make the adjustments)
If I start to see obstructive events again, then I start going back up. If the central events continue in addition to the obstructive events, then I will change to bi-level after a trial of C-Flex.
If the Central events start from the early stages of the titration, I will consider changing to Bi-level sooner. The bottom line is there is a lot of trial and error durring a titration.
The other thing is about the scoring. All events get scored. It may be an obvious post arrousal central, but all events get scored.

Need opinion on PSG results
cohodependent,
my events were hypops. centrals, and mixed. the pressure that the tech maxed out was at 11cm; however, my sleep doc says that there were "residual" apneas present that I could go to 12cm. No, right now I am unable to go pass 10 as that's when the centrals and the machine goes crazy. The machine has been calibrated and it is accurate.
I am trying to get the cd/dvd of my sleep study but the hospital is not co-operating. Perhaps under the direction of my sleep doc.
For me a bilevel is not good according to the people in Boston Israel. I was advised that based on my information, PSG et al, it would now be considered by some physicians in the Boston area to be malpractice to offer you CPAP or BiPAP as a therapy once the diagnostic criteria for CompSA have been met.
