When I first got my machine, after my sleep study, it was determined I should be at 8, so I came home on a fixed setting at 8. However, after 6 weeks I was still having high AHI 15-20. They told me they were going to switch it to a variable between 8-12 or 8-13.
My question is.....can I tell by looking at my machine if they did that? It's still showing 8.0 cmH20 when I turn it on.....
2 weeks after they told me they were changing settings my AHI still high. Last night it was 19.
I have Phillips Respironics REMstar Auto A-flex System One.
if you had it set to 8-12 or 8-13, it would start at 8, and the screen would say 8 when you start. later, if you watched it thru the night, it would display higher pressures as it changed.
