Hi,
I am just going to start using my APAP again after 3 years. Just had an overnight sleep study, I used to have 39 events per hour but the latest study said it done to 7.6 due to major sinus surgeries (turbinates removed) a few years ago. I just started reading my owners manual for my RESMED S8 Autoset II and the machine had been set to provide some Efficacy Data.

Can anyone tell me want these abbreviations mean:
PRESS (I am guessing pressure, but is it maximum or average?)
AHI (Apneas, but per hour or for the whole night?)
AI (cannot even guess)
HI (cannot even guess meaning, maybe high something).

Thanks Dave

Pressure but not maximum or average...instead it is 95% pressure meaning that for 95% of the night you were at OR below that pressure. People tend to forget the "or below" part of the definition.

Per hour average of the AI plus HI

Apnea Index...per hour average for obstructive apneas

Hyponea Index..per hour average for Hyponeas

You might like to get the provider manual for your machine as it explains things in more detail.

Pugsy,
Thanks very much for your help, I just sent the email to get a copy of my CPAP setup manual.
