Right. If obstructive events are the main problem, it usually helps to increase the pressure, especially the Min Pressure.

Your post count is not yet 7. I think you may be able to post several short posts (like "Hi") until you reach your daily limit or until your post count increments at least to 7. After your 7th post, I think you can post a link to an image.
Quote:According to the daily report, CA is most part of the events. During night when I am about to fall asleep, sometime I can sense that I stop breathing and I wake up to breath. So I think now CA is my main concern, hopefully turning EPR off will help resolve it.
Having central apneas as we are falling asleep is not uncommon, maybe even for people who are not very susceptible to CA's.
I'm glad turning off EPR helped. To me that means it is likely you will not be able to use a standard bilevel machine (which, like EPR, produces a pressure drop when we breathe out and a pressure boost when we breathe in), that you will need an ASV machine (unless simply by turning off EPR you are lucky enough that your AHI reduces to less than 5).
I also suggest increasing your Min Pressure gradually (changing the Min Pressure setting not more than 1 or 2 cmH2O per week) to see if a higher Min Pressure improves or worsens your AHI. Every night will be at least a little different in some way, so our AHI varies each night. After making an adjustment it is often best to leave the settings unchanged for a week or two, so we can obtain an average over many days before changing settings again.
