RERA vs. AROUSALS

[tedburnsIII]

RERAs apply in determining RDI. Do 'arousals' or 'micro-awakenings' apply as well in computing RDI?

What is the distinction between them- that one requires respiratory effort and the other does not?

My limited reading on the subject indicates that 'arousals' as to persons 50-60 years of age are considered 'normal' at 20-22/hr.

Thus, arousals appear normal up to 22/hr but what is the story with RERA? RERA must be some kind of event that matters, whereas 'arousals' ???

I may be wrong, but I understand that RERA (was it Respiratory Effort Related Arousal)? is breathing-related arousal. RERAs are subset of arousals.

Here is an interesting study about arousals and heart rate.

RERAs have to last a certain amount of time to be counted in RDI. There is a tendency for women to have this and hypopneas rather than apeas. As a result, many women with OSA don't qualify for machines because Medicare only considers AHI and many insurance companies follow that lead. I barely qualified myself, although my oxygen level would have qualified me for an exception due to another health issue.
