Any clues to differentiate OA from CA just from data?

Hi,
I'm using S9 Vpap Adapt which scores events but cannot differentiate Obstructives from Centrals. RT would like to see fewer events so is keeping me on the machine for the time being with Epap increased from 9 to 10, on the assumption that most events are obstructive, its worse on my back so not a bad assumption, but I'm wondering if anyone has developed clues from Flow Data that might help identify Obstructives. RT says there is often a blip in flow with OA as the muscles still attempt to breathe, but I can't distinguish it. Anyone?

btw - snoring line shows zero, guess I'll try some fake snoring tonight to see if it registers

Did you by chance see this topic? viewtopic.php?f=1&t=74249&st=0&sk=t&sd=a

If not take a gander through it. I did some looking into the issue of OA and CA for the Adapt for Nate. There appears to be no reliable way to segregate them or Resmed probably would do it.
