i hope theres someone whos kindly enough wanted to help me is anyone expert at central sleep apnea and obstructive sleep apnea? im confused why does my symptoms happen randomly. something i consume/take could make it worse. and when my health condition drop it got worse too. i've had 2 sleep test. 1 was long time ago in hospital but i couldn't sleep troughout the night so it would such a waste. one was recently, a home sleep test with oxymeter, 2 belt, and the nassal cannula (but it keeps getting off my nose) i used xanax low dose so i could fall asleep easier but later i found out that benzodiazepine prevents from deep sleep and i did notice that i got only light sleep. and i feel fine trhoughout the night (no attack). the result appeared to be in normal range only says some breath flow limitation. my symptom was started long time ago since i was a child i get awaken in the middle of the night cause i wasnt breathing and it keeps happening ever since. i didnt know what it was back then when i was a child i thought i was too lazy to breathe or i should teach myself to remember to breathe and it will disappear by itself. (didnt know about the autonomic nervous system) the problem is it happens randomly eventhough it has happened many times since the first attack but sometimes there are times when it didnt happened but sometimes its so terrible it almost killed me and causing me to stay awake. sometimes i also get what i learn later is breathe flow limitation. i noticed that i am breathless cause my throat was closing when i was about to relax and doze off. but then again it doesnt happen everyday 1 thing i noticed it likely to happened when my health condition worse. and cause of all that factors it confused me how to be able to detect those 2 issues on sleep lab when the attack is happening not when it isnt. cause it happens randomly. not to mention that sleep lab costs quite a fortune here and to me. also i read that apnea could cause heart problem and since i do have heart problem theres a possibility that it causes by that or apnea could makes it worse. i cant ignore that. also that one issue prevents me from any operation that needs sedation/anesthesia which i might need since if the attack strikes me when im couldnt be able to awake i would die. those 2 problems concerned me but i dont know what to do. please give me inputs i would greatly appreciate it.
