I see nothing in this literature which describes my central apnea. I am not saying central sleep apnea, because I have it 24/7 and have for 25 years. I've been diagnosed with OSA for 13 years and using CPAP for that period of time. Beginning in 1990, I have had periodic (never measured) short gasps/snorts/deep breaths which have been noticed by others. The first time someone asked "Carol, are you OK?" I was startled. Once, after I gave a lecture a doctor approached to ask if I needed oxygen. Like any other mannerism, such as a tic, if you do it for all those years its just part of who you are, how you act. I am an extremely compliant CPAP user, all night every night, traveling whatever. In November, 2015 at my annual check up my sleep doc, looking at the chip data, muttered, "Lots of breakthroughs, looks like central, nah......" First time the word registered with me, and I came home and began to research (I'm a RN) and had an AHA! moment. Made appt to TELL sleep doc what was going on, and saw cardiologist next day - told him too. Now we know why 2 ablations, 15 cardioversions, every known medication known to man hasn't touched my A Fib. Measured my O2 sat, 98%. At this point (I'll be 82 in July) all that will be done is check oxygen sat periodically. I think I should be a research project candidate for somebody!
