My AHY is 17 on the info screen of ResMed S9. What does it mean?
I have just started using CPAP the S9. The user manual is
very short and does not explain the screens or what the data means.
Is there a way to download the data at home to my home PC analyze and look at the data and then send it to the clinic for additional analysis?. Is there software for S9 that I can download to do that?
E
Can someone explains what AHI OAI CAI means and how to interpret the numbers below?
I am using ResMed S9 and my presure is 7, AHI= 17.8, OAI 15.5, CAL=0.4

I just would like you to know that the hypopneas of the S9, and all ResMed's flowgenerators, are not true hypopneas. To determine a true hypopnea, and additional oximeter is needed to measure a 4% saturation drop. The flowgenerators are very sensitive to flow limitations, and that's what you are looking at. As a healthcare provider I am more interested in the AI (apnea index) than the HI (hypopnea index).
The recently launched S9 flowgenerators measure centrals, but also specify an apnea to 'other' if it cannot determine whether it's a central or an obstructive apnea. It's a neat feature.
BM, What should the HI and AI numbers be?

Don't want to rain on anybody's parade here (nor be a smart ass), but the Resmed website says the figure it uses for scoring the AHI, AI and HI is NOT THE AVERAGE. Instead, they use the MEDIAN because it is more "robust" than the average.
