Are there any indications I should watch out for that would suggest that APAP would work better for me, such as particular events in SleepyHead or physical indications?
Static pressure can be an effective treatment for OSA, if the pressure is at a therapeutically effective level. The only disadvantage, is that the pressure needs to be generally higher than an APAP to cover all stages of sleep, sleep position and other factors. Indications that pressure may not be optimal are increases or high residual snores, hypopnea, and OA events. CA events can generally be ignored. If the machine measures flow limitation and RERA that can also be considered in optimization, but most CPAPs do not measure those. Snoring is an early sign of airway collapse and is generally used in APAP as a signal to increase pressure.
CPAP pressure can be reduced to the point where any snores or AHI begin to increase, then should be reset back to levels where those events are acceptable. It's a little more work than APAP, but both machines essentially function the same, and both are CPAP variants.
