Pressure reductions - what's happening?

Post by dataq1 » Sun Dec 12, 2021 2:20 pm

What is happening here (see attachemnt)
More specifically, why would the pressure be reduced 10 seconds after an Obstructive Event (reduction from 12.7 to 10.7)
BTW, the pattern of breathing beginning at ~ 01:17:30 remained consistent for the next 2.5 hours after which snoring occurred (then all bets are off)
So my question is two fold:
a) is there any significance (or what might be occurring) during the breathing pattern seen ending approx 1:17 (which had been going on for about 45 minutes)
b) why would the Apap reduce pressure almost immediately after the OA at 01:17?
