Does 10 EEG arousals/hour mean sleep apnea?
Does 10 EEG arousals/hour mean sleep apnea?
I was always pretty good at algebra but I can't make sense of this set of data.

Normal AHI is 0-5; above that and you have sleep apnea.

Normal RDI is 0-5; above that and you have sleep apnea.

RDI = AHI + RERAs/hour*

So, if you have an AHI of 5, even a single RERA all night means you have sleep apnea!

Yet normal people have at least 10 EEG arousals PER HOUR - which are essentially RERAs!!**

Where have I misunderstood?


*A RERA is an abnormal breathing event which does not meet the criteria of an Apnea or an Hypopnea, but is an “arousal” event associated with a respiratory effort as noted by EEG.
