My thanks to everyone here who has posted, both questions and answers. This is a totally awesome resource, and I am glad I found it.
Accept my apologies for a potential re-post of this question, however the search function will not accept a search with terms like "AHI", "AI", or "HI" in it as they are "too short"
(there should be a "Doh!" smiley)
Looking at my efficacy data, I see, (among other things), readings for AHI, AI, and HI. (the rest are things like pressure, how often I use it and for how long, leak rate, etc.)
So far, I have not found anyone who discusses what these readings actually mean, (i.e. their definition), and their relevance, (i.e. what do these readings actually tell me.)
I know that an AHI of less than five is boss, (mine is currently 3.2), and the sub-readings are AI = 0, HI= 3.2.
An explanation of these readings, their meaning, and their relevance would be gratefully appreciated!
What say ye?
