What is the least a person's SpO2 can fluctuate during REM? - rbwilli - 08-27-2017 When I use a CMS-50F pulse oximeter to measure my SpO2 overnight, I get the same pattern every time: the first half of the night is very steady, and the second half of the night is much more "noisy." I understand that if a person has sleep apnea, muscle atonia during REM sleep can cause apneas, which would explain why their SpO2 drops further and more frequently during the second half of the night. I don't think I have sleep apnea, but I sometimes wonder whether I might have more mild breathing problems. My question is this: What is the least a person's SpO2 can fluctuate during REM? In other words, what does SpO2 look like for a person who is 100% free of all sleep-related breathing problems (apnea, UARS, etc.)?
