New APAP user
About a week into APAP therapy (started end of June) for diagnosed OSA — baseline ODI-4 was 8/hr. AHI is now sitting under 5 most nights, which I'm happy with, but a large share of my remaining events are flagging as CA (central) rather than obstructive, and I'm trying to understand whether that's something to act on or just ride out. Another issue is that I am getting very low deep sleep numbers like 30 mins or less per night.

Current setup: APAP 5–20, EPR 2 full-time. Pressure is running low (median ~5.3, 95th ~6.6) and leak is basically zero.
What I'm hoping to get your read on:
Given I'm only ~1 week in, do these CAs look like treatment-emergent centrals that tend to settle on their own, or a pattern worth addressing now?
With centrals in the mix, would you narrow the pressure range or move to a fixed pressure rather than wide-open APAP? My understanding is that chasing pressure can sometimes make centrals worse — is that what you'd watch for here?
Does EPR 2 help or hurt in a case like this? I've read pressure support can aggravate central/loop-gain instability — curious what others have seen.
Anything in the flow-rate traces that tells you these CAs are genuinely central vs. mislabeled?
