Then they see the residual AHI is 6.7 (not really a show-stopper, and certainly not able to justify ASV) and say "Hey we can fix that with more (HAHAHAHAHAHAHA) pressure."
That assumes the events are pressure-responsive (obstructive) and not pressure-sensitive (some/most kinds of centrals).
So in her mind, she's thinking "The AHI was 36.7, now it's 6.7", and pretty clear why she
continues to believe that straight CPAP therapy is the way to go.
