If ou look through your respiratory flow rate chart zoomed in close enough to see flattening from flow limitation, then where it goes back to normal or larger flow rate than normal, that may be RERA. Whether that corresponds to an awakening we can't say. Arousal are just sleep stage changes and may or may not be awakening.
Your results look great, and you've done a very good job of optimizing. I don't see how settings might be contributing to arousals as the pressure is nearly steady and appears to control events and flow limitations well. About the only way to improve on this would be with a Vauto bilevel machine...maybe. I hope you will continue to feel more refreshed as you continue to use these settings, however keep in mind "perfect sleep" is elusive, whether you use CPAP or not, and it doesn't seem to get better with age.
Thanks Sleep rider for the explanation and words of encouragement.
Nevertheless I have a question.
Last night, my AHi jumped from 0.52 (09022020) to 1.87 (10022020)
I noticed some strange long lines at 1230 and 0145 which seems to correspond with the minute vent charts
At 0312, this could probably be during my toilet break but why is the minute vent going down instead of up like the leaks at 1230 & 0145 ?
My CAs have also increased and seems to be clustered. I didnt feel that good upon waking up and felt a bit bloated.
Any possible explanation ?
P/S : I did not pull off the mask except during the toilet break.
Could the long lines of leaks be mouth breathing incidents ?
