I've used my machine every single night for the last 11 months, averaging about 7 hours a night of use while asleep. Here's a summary of my results for the last 7 months (I've excluded the first 4 months, which weren't terrible, but not respresentative of my current situation since I was fiddling with different masks, chinstraps, mouth tape, and becoming acclimated to sleeping with an APAP machine):
AHI -- monthly averages between 2.0-2.7, mostly in 2.4-2.5 range
OSI -- monthly averages between 0.2-0.5, mostly in 0.2-0.3 range
HI -- monthly averages between 0.5-0.8, mostly in 0.6-0.7 range
CAI -- monthly averages between 0.9-1.9, mostly in 1.4-1.6 range
Leak Rates -- 90% rate monthly averages between 1.2-7.2%, mostly in 6-7% range; 0% over the Leak Threshold
I've made a few modest pressure adjustments over the last seven months, with little apparent effect. In November the setting was 9.6-13.6 cm, December was 9.6-14.0, January-February was 10.0-14.0 and March-May has been 10.0-12.8. My in-lab sleep study titrated me to 11.0 cm CPAP.
I'd like to reduce the Clear Airway events, now that I've adjusted to APAP therapy, but I'm unsure whether that's a reasonable endeavor.
