No issues with facial hair and a full face mask myself. Deviated septum makes a nose mask a no go. Unfortunately, even adjusting the heat pad under the water tank and maxing out the humidity I tend to wake up after 2-5hrs max with terrible dry mouth and dehydration. I do take a bunch of medications, which can't help, but without the machine I can sleep much longer (6-10hrs, more if I haven't slept for days).
Right now I'm off the machine. Type 1 bipolar and an obliterated sciatic nerve seem to be my bigger issues. My first sleep study said, of the two main metrics, one number was under and one was just over the point of concern. I opted not to get a CPAP machine at that point.
Then I was having more sleep issues, which was most likely due to the bipolar issue, and medication changes, but I figured that since I have excellent insurance, why not go back and see if anything changed? Worth one crappy day or two.
Now the second test was interesting, because the doctor said she had never seen anything like some of my numbers. The two main metrics had increased enough to give the machine a try, so I did. However, apparently my oxygen saturation fell down to the 79-83% range and stayed there all night (it was low the first test, but not freakishly low).
The doctor was sure that the equipment was broken, but it wasn't. Due to my medical issues I see my GP monthly, so I have a solid record of my weight, blood pressure, temperature, and oxygen saturation since 2008. From that I know my normal, everyday saturation is lower than most.
Every time I see a new nurse I have to tell them it's not the digital finger monitor, it's just me. I've tried putting the oxygen monitor on my right pinky, which is the only finger I don't use playing bass, so it's not an issue of calluses or torn up, more delicate arteries from blisters, burns, or cuts (I cook a lot and like knives, plus I've played until my fingers have bled more times than I remember [I keep pieces of electricians tape on my rack for this]).
I've never been all that vascular, even when I ran 12mi+ a week (up at 5am) and worked out 3hrs 5 days a week (3-6pm) and got down to 7 or 9% body fat. I forget which, I just know the athletic trainer guy (was a gym at a D1 college, so there were academic/professional sports medicine folks that would give you those numbers). All I recall is him saying I would go temporarily sterile at 4%, which was fine by me at the time.
I get a full blood workup twice a year and it always takes a while to find a vein in the lab, and when nurses try it in the exam room they almost always call in someone from the lab. But I see my doctor today, so I'll have him pull up the oldest info he's got just to see if there's anything interesting or any pattern.
Anyone else have abnormally low oxygen concentration? I'd love to hear from both pick and finger style players to truly rule out calluses or other possible finger wear and tear. Never woken up gasping for air, but with so many medical professionals reacting the same way, clearly something is off.
I have an ultra crazy theory, but need a couple more tests to really see if I'm onto something.
