So setting my my VAuto to EPAP 8.2, PS 3 was to initially create an experience similar my APAP (11.2 EPR 3) Which effectively gave me a pressure on exhale of 8.2.
On the VAuto we just set the EPAP to be the effective pressure we want on exhale.
Basically, we establish a minimum expiration pressure that manages our events and keep it at that, increasing PS, will never drop below that.
It's the EPAP that holds your airway open, if that's too low, then your airway closes, and you can't initiate a breath, so the machine will never switch to the IPAP pressure... so IPAP (and thus) PS don't have anything at all to do with preventing obstructive apnea... (unless, like me, you see little attempts at breathing before an apnea which was why I set the trigger to very high, thinking "well, if I'm trying to take a breath, but it's so choked off by my throat closing, maybe if I set trigger to very high, then the machine might be able to help me through it... and it seemed to help. )
