NRAH: Non-Responsive Apnea/Hypopnea Index - verysincere - 03-31-2021

I see the NRAH Index discussed in some technical articles and I also noticed that the term is defined in the SleepyHead Wiki.   ("It is detected when the patient has at least 2 apneas and/or hypopneas, the pressure-level of the therapy device increases at least 3 cm H2O, and the patient continues to have apneas and/or hypopneas.")

This NRAH Index would seem to me to be a very valuable metric. Why don't we see it within OSCAR reports?

OSCAR (Open Source CPAP Analysis Reporter) reports the data generated by CPAP and BPAP machines. If it's reported by the machine, Oscar shows it, but if it is not reported, by the machine, Oscar does not do independent analysis. We look for clustered apnea and hypopnea events when helping members with their charts because it is a strong indicator of positional apnea. http://www.apneaboard.com/wiki/index.php/Optimizing_therapy#Positional_Apnea
