Unfortunately, since last time my best numbers are about twice what they were before (from below 2 to about 3.5 AHI). A SWAG nightly average would be between 4 to 5. Some of this may have been due to the gain of about 10 pounds (due to medically-directed "thou shalt not do squat" associated with the above recoveries - I'm currently in the process of recovering from the recoveries), not sure how much.
Some background info since the last time:
- Bonjour suggested that I up my minimum pressure from the factory-default 4 to 7. I made this adjustment at that time: may have improved things a small amount.
- Based upon leak rate, at the suggestion of a couple of folks I tried to switch to a cervical collar: both a "standard medical" foam one and the "Releaf" travel version. Despite attempts to "tough it out", multiple nights trial with each resulted in waking up with a significantly-stiff neck and a splitting headache due to the pressure that this was placing on my neck. Aside from getting some resulting quality time with my chiropractor, my numbers were actually worse, due to the fact that the collar was essentially forcing me to sleep exclusively on my back. I'm therefore back to the chinstrap at this point.
- During one surgical recovery when I was directed to sleep face down, my numbers were consistently below 2 AHI, frequently below 1 AHI. My apnea is very positional, with a significant tongue-obstruction component. Unfortunately, forcing myself to sleep all night exclusively on my side or face down creates other physical problems.
- I'm still battling somewhat with my mask. The AirFit P10 seems to work best overall from a comfort standpoint, although it's a bit sensitive to being bumped when I shift position. My AirTouch F20 is okay for short naps, but AHI numbers were actually worse when I gave it multiple nights, not to mention the couple of experiences of being force-fed air. I tried the AirFit P30i, but couldn't find a way to keep the pillows from being painfully forced into my septum.
