I think I do best when my Min Pressure is set near my average pressure. For a time I kept my Min Pressure as low as I could stand it, to see if my CAI would get lower, but I found that my CAs were occurring just as often when my pressure was low as when it was high. Seemed to make no difference in my case.
One thing that quite a few patients have observed is their CAI gets better when they turn off EPR. Now that you are used to the therapy, maybe you could try turning off EPR for the next month and see if it helps in your case.
Just to add some more info to the discussion, my CA index went up dramatically when I switched from a CPAP at 13 cm of pressure to a BiPAP at pressures of 13 cm IPAP and 8 cm EPAP.
For some unknown reason, and this has been documented, the lowering of the exhalation pressure induces central apneas.
Mine were short in duration and the frequency fell to an acceptable level with time.
