I just started a week ago, after an at-home sleep study (50+ AHI), then a study with titration at a sleep facility. Used a nasal pillow, the tech came up with 10 cm h2o.
First fun complication, I had a dacryocystorhinostomy (DCR) a few years back, which cuts a direct port from my tear ducts to my nasal cavity. Helped my tears drain, but now any pressure in my nasal cavity produces airflow into my eyes. Using a nasal pillow causes air regurgitation into my eyes, which will end badly - causes dry eye, eye infections, and a really strange flapping sensation that makes it tough to sleep.
So now I have a FitLife Total Face mask. I struggled through the first several nights, and my results (in terms of events) were pretty discouraging. Average 34 AHI, worst night was 49. I called the doc twice this past week, only got the med tech who said that I should persevere until my next appt on 2/1. Patience is a virtue, but waiting for two weeks with severe apnea while struggling seems heroically patient, and I'm not that.
With the help of this board, I figured out how to change my machine to Auto, set with a min of 8 and max of 12 (baby steps). Last night my score was 28, 15 obstructive and 13 central. SleepyHead is also great - the med tech told me that 35 isn't that bad, because the "events" number is made up of lots of confusing things that I couldn't possibly understand. Grrr.
My trouble is with the FitLife mask. It's well made, seems to be a good fit for my face, but leaks like crazy once the pressure jumps to 12. 10 was borderline, but 12 is tough. I have ratcheted down the straps, but that's getting so tight that it's painful. Anybody have experience with cleaning, glue, gaskets, staples, nail guns? Any advice would be greatly appreciated.
