Question about BLCPAP trigger and cycle settings

Question about BLCPAP trigger and cycle settings
Good day,

Recently changed from the AirSense 10 to the AirCurve 10. Sleeping much better on it. But I have noticed one thing.

On my AirSense, I usually had between 0 and 1 Central Apneas per night. And with my OAs limited to around 2 or 3 a night I was doing well. Generally an AHI of around 0.5. Since changing to the AirCurve and upping my PS to 4 (versus 3 on the AirSense) I have noticed that my Central Apneas have increased even though my IPAP has not gone up from my old settings. Looking at the last week I am seeing small clusters of CAs each evening, totally about 7 or 8 per evening. Not a big concern but since it is different than before I thought I would reach out to the members of this forum.

In the attached OSCAR screenshots you will see that the cluster was very early in my sleep cycle from 2 nights ago. In last night's sleep, they were later in the evening.

I have seen some mention of the Trigger and Cycle settings. Can someone elaborate on them and if changing them from the default of Medium to something else might help bring down my CAs to where they were before.

I do like having my PS at 4, it feels much more comfortable and natural than EPR of 3. And my I:E ratio is 1:20 now which seems better than the 0.8:1 ratio I had on the AirSense w/ EPR 3.

thanks.

RE: Question about BLCPAP trigger and cycle settings
many vauto users including me set trigger to high or very high to help avoid central apnea.
  Shy   I have no particular qualifications or expertise with respect to the apnea/cpap/sleep related content of my posts beyond my own user experiences and what I've learned from others on this site. Each of us bears the burden of evaluating the validity and applicability of what we read here before acting on it.

I would change the trigger to high for a few days and see how that goes.

Success! Thank you. Changing Trigger from Medium to High worked. 0 CAs last night. Good night's sleep w/ only 1 OA and 1 Hypo.
