Sleep study

I had my sleep study in preparation for my WLS. It came back that I do not have sleep apnea, but it did show that at one point in my REM sleep my oxygen level went down to 74 for 14 minutes but then retuned to normal. My doctor had an overnight oximetry done at home, and now has me at 3 liers of oxygen overnight until another oximetry shows other than low oxygen. My RNY surgeon does not seem to be phased by this as long as I do not have sleep apnea.

did anyone else have something like this happen?

No.  I have sleep apnea.  But I do think its a good idea to get the oxygen, it helps you feel more alert and metabolize better.

Best wishes in your journey!

Thanks so much for the information, especially about the metabolization. I have been using the oxygen almost every night.

Sleep position matters too. Positional asphyxia occurs when you sleep on your stomach but don't roll over when your air exchange suffers.
