I have been losing weight so I thought I would try adjust the range down a little to see what happens. Somewhat surprising results. I have slowly reduced the pressure range down to 8-10.8. I still wind up with a mean pressure very close to the max (10.6) whatever it is set to, BUT my AHI is now typically 1-3 !
Something is going on here. Seems like the higher pressures are inducing apnea events and/or hypopneas are causing the pressure to stay high or ???. My general impression is my sleep quality has improved as the pressure and AHI get lower.
I was expecting that if a lower pressure was sufficient the S9 pressure result would automatically adjust lower along with my AHI becoming lower.
I am losing confidence in the S9 algorithms.
