I didn't have much luck and this was with the DME applying the settings per my doc's Rx. They changed the auto Rx to Min EPAP 5, Max IPAP 25 with PS from 2-8. Problem is, the pressures would never get high enough to work effectively. The EPAP stayed pegged at 5 no matter what and the IPAP would never get over about 12. After two nights my AHI had jumped up to 8.4 (even with zero large leaks) so I changed the machine myself back to Bi-Level. My doc did authorize a reduction in pressures down to 15/11 and last night my AHI was 0.4. But to control leaks I'm having to screw down my Quattro FF mask to the point where I get the hamburger nose syndrome every morning.
I'm theorizing that something they did in the PS settings would not allow the machine to truly free-float between 5-25 cm but the doc's RRT swore it was set right. Here's the Encore Basic chart for that night.
Any thoughts would be appreciated. Theoretically anyway I would think that an automatic setting from 5-25 would be ideal in trying to control leaks, but it doesn't seem to work for me. I just can't figure why the pressures didn't get any higher than they did, obviously causing a rise in AHI.
