Did anyone have difficulty with this during or after surgery?

I have sleep apnea and I use the CPAC.  I'm worried about the impact of anesthesia and narcotics during and after surgery. I am going to discuss this concern with my surgeon and anesthesiologist before surgery although, I'm sure they have extensive experience in weight loss surgery and that they will take appropriate measures to maintain the airway for a safe surgery. Did you have any experiences during surgery with oxygen levels because of sleep apnea? Did anyone have difficulty with this during or after surgery? If so, what were they and how

i have sleep aptnia and had my toncils removed  a few years ago. they used general anesthesia. and i had no complications. just be sure to inform them of your  cpap settings and severity of  aptnia. i woke up after surgery with a ventolator mask on me. and they said the procedure went very well no complications.
