Thrice...did you get a copy of your sleep study? Your sleep study will tell you how many obstructive apneas, central apneas, hypopneas, and RERA's (respiratory effort related arousals). I have almost all RERA's and 7 Hypopneas and am technically "UARS - Upper Airway Resistance Syndrome." If you have the report, that can help a lot in determining which.
yes, i have a copy but it's not with me right now. i'll be able to look at it tonight though. i do remember that the majority were hypopneas. there were 2 centrals which he said was normal and there was a decent number of obstructives if i'm remembering correctly. my oxygen levels stayed in the normal range.
