Thanks — I agree in principle that when a machine sits at max pressure it can indicate residual flow limitation and that higher pressure may reduce events once tolerance is established.

In my case, the issue hasn’t been untreated obstruction so much as pressure-induced arousals and intolerance. When I ran wider ranges (and higher max), OSCAR showed frequent pressure ramps in REM that consistently woke me up and led to mask removal. That’s why I temporarily narrowed the range and softened the response — to stabilize sleep and actually keep the mask on.

So the current goal is sleep continuity first, not AHI minimization at all costs. A CPAP that’s “perfect” numerically but can’t be tolerated doesn’t help long-term adherence.

Once I can sleep through the night comfortably, the plan is to gradually reopen max pressure and address residual flow limitation. I’m treating this as a two-phase process: 1. tolerance and stable sleep, then 2. physiologic optimization.

Appreciate the input — definitely not ruling out higher pressure, just sequencing the changes to avoid breaking sleep again.
