Increased AHI
I have adapted to my mask and been sleeping (not more than 6 hours as at some point throw it off!) and my AHI for most nights has been less than 1. Last night it was 1.7 and I could tell I was not sleeping well. What causes a rise in AHI? Does this mean that the pressure needs to be changed? I can't correlate it with anything in particular...

Have you downloaded the SleepyHead software?

The only way to determine how well your therapy is going (besides how you feel) is to use the software.

A rise in AHI could be from many reasons. Without seeing some of your data, it's hard to advise.

It is normal for AHI to swing from near zero to as much as 3 for well-treated people. One night at 1.7 is meaningless in the context of treatment. Do not change anything or worry about it.
