Yes.

I wouldn't be discouraged because the above isn't entirely true. Remember that in your diagnostic sleep study, you were battling mostly apneas. Your problem now is residual hypopneas. The academic literature I've read says that yes, hypopneas should be taken seriously and treated, but it's a better problem to have than pure apneas. One of the problems with AHI as a statistic is that it treats all of these types of events as equal, when they are not. Another reason I wouldn't be discouraged is that you have good nights and bad nights. Your average long-term AHI still seems to be an improvement compared to your baseline diagnostic.
I would give it a few more days, but so far, your data exhibits many similarities to mine, JIMCHI's, and other posters'. Despite the underlying causes being different, that may ultimately be helpful. One of the questions I plan to ask my neurologist this coming Friday is precisely about such large variability in night-over-night hypopneas.
The increase in min PS could be having an iatrogenic effect upon your respiratory drive. This was the case for JIMCHI -- see
viewtopic.php?f=1&t=60687&start=105#p573970. If this persists, -SWS's logic would suggest lowering min PS again and allowing the machine to increase it as needed. Remember that your ASV can change your IPAP
very quickly with its breath-to-breath algorithms, while it adjusts EPAP more slowly.
Other than feeling discouraged this morning, how else did you feel? Are your current settings better, worse, or the same as your previous settings in terms of how you feel?

With due apologies to both Paper Nanny and JohnBFisher for my inability to turn the other cheek: I've read thousands of old posts here as part of getting myself educated, so I'm pretty familiar with the evolving cast of characters. Only one other poster has made the emphatic and ridiculous claim that ASVs will "burn out" if max pressure is set to a high value. That poster shares your writing style, your advocacy of rampant dial-twisting, your love for tweaking PS, and your propensity to state (incorrect) beliefs as fact. Miraculously, he stopped posting the very same day as you began -- even in the same thread! This doesn't strike me as coincidence.
I respond not because I'm worried about Paper Nanny taking to heart, say, the advice to plug her ventilation holes, but rather because people's searches lead them back to these posts days, weeks, months, and even years later. It would be tragic if a new ASV user took some of the things written here as gospel simply because the poster gave his advice using a sure and authoritative tone.
