Explanation and Range of CPAP Numbers
08-10-2012, 02:12 PM
Hi. I have a ResMed S9 Elite. I opened the data card in ResMed Version 3.16 software. Can someone please explain the numbers and the normal ranges. What do the numbers mean as to how bad my apnea is? (Apnea Index, Obstructive, Central, Hypopnea Index and AHI in particular). What is the acceptable leak level? I a;lso saw a sotware called Dream Driver. Is it available and if so where? Thanks, BobF.

Wiki page on acronyms:
If a wiki page exists for the acronym (or what the acronym stands for), it will have a link to that page.
Such as for the AHI:
But, in a nutshell, you want the AHI to be less than 5. I think it is the same for central events.
I think the leak level depends on the mask.

If you to to the webpage for your mask in ResMed (I am not sure about others) there will be a table and your intentional leak rate is determined by a combination of mask and pressure. It is on a graph that show the leak rate increase as the pressure is raised.
As always, YMMV! You do not have to agree or disagree, I am not a professional so my mental meanderings are simply recollections of things from my own life.
