I should first note I've been going through some very difficult health troubles that tied into hypertension, and now GI issues.
I was diagnosed with "mild to moderate" apnea based off a home apnea test that some cardio doctor ref'd me to.
I am not sure how the test I took was accurate, as the heart rate sensor fell off early in the night because it couldn't stick to my chest.
I really do believe I may have sleep trouble, as daytime fatigue along with much difficulty falling asleep has been the biggest problem lately, as it seems to trigger hypertension.
I have had the resmed cpap machine for over a week now, but the guy who set it up in my home mistakenly gave me a WIDE fitting f30i mask, and it does not seem to seal or work well.
Later, they sent me the n30i nasal mask. I tried that, but don't seem to be a nose only sleeper. I've also been having lots of trouble with burping, so the nasal mask only makes that worse.
I'm really looking for the best possible mask out there for someone new. Having lots of trouble adjusting to the pressure. When the home setup guy put the flow to 14, i felt chest pains and worse. Since then I haven't set the machine to do that, but did turn off the ramp. It still sets at a range of 6 to much higher, I guess when I actually fall asleep.
I don't want to be worries about the cpap somehow choking me as this is the only problem I've noticed most with my sleeping. The moment I fall asleep, I seem to sort of forget to break sometimes, and wake back up panicked. Strangely, I think the same thing happened with the f30i mask when I was close to falling asleep.

Between my hypertension problems and all the misery it's caused me, I feel overwhelmed at times. I hope to actually use this cpap someday soon. THanks much for any help or advice.
