Hi OpalRose,

That is very interesting.

It is well-known that, with some patients, limiting the top pressure will lower the number of central events which occur.

Theoretically, however, raising the pressure should tend to reduce RERA, because true RERA events (true Respiratory Effort-Related Arousal events) are obstructive in type.

I suspect your machine was mistaking some central almost-but-not-quite-hypopnea caused arousals for RERA-caused arousals.

Congratulations on the excellent job done in fine tuning your therapy.

Membership in the Advisory Member group should not be understood as in any way implying medical expertise or qualification for advising Sleep Apnea patients concerning their treatment. The Advisory Member group provides advice and suggestions to Apnea Board administrators and staff on matters concerning Apnea Board operation and administrative policies - not on matters concerning treatment for Sleep Apnea. I think it is now too late to change the name of the group but I think Voting Member group would perhaps have been a more descriptive name for the group.
