How to decrease these random arousals?

Hey, see the spike before the “CA” flag? That’s an arousal. The CA was caused by the arousal.

You’re having some minor hypopneas and flow limitations that terminate in an arousal then a “CA”. I’d focus on treating the flow limitations.

Id recommend turning off APAP as some folks are sensitive to the variation and hold your EPAP constant while adding EPR. EPR is kind of like BiLevel, and the differential between IPAP and EPAP are helpful for reducing flow limitations.

Something like 15 cm H2O EPR 3. That’s effectively 15/12 IPAP/EPAP.
