Do you have a Windows computer by chance?
What are the PS minimum and maximum settings?
Without seeing the detailed reports and when the events are getting flagged....and assuming that you aren't spending large amounts of time awake with the machine and mask on....maybe more EPAP minimum to see if it will deal with the obstructive stuff a little better.
PS 0 min, 20 max
Sorry, I don’t have access to a windows machine or I would use encore.
Some nights I may have as much as 1/2 hour awake with mask on. On these nights if I check ahi on the machine I notice that it drops from the time I awaken until I give up and get up and start my day.
