Question about endoscopy procedure (depression, nose, sleep, cause)

[rlrl]

I had the upper endoscopy today and there was no problem. but i have a question, why did they put an oxygen mask on me after they injected me with the first shot (the second one was the anesthesia which put me out)?

was it because i told them i believed i had sleep apnea (I have a sleep study in August) or it's just standard procedure? does the first shot deplete you of oxygen? how does it work?

No, it's routine. I don't know what you got first, I only had the one of propofol.

i was told the first shot is some type of saline preparation

standard procedure - the sedation used in such procedures can cause respiratory depression - use of oxygen is entirely normal

i freaked out a bit when they put the oxygen tube in my nose because it reminded me of my folks when they were dying and i never had this done before, and i had thoughts of if the tube weren't in there would i die right there

all i can say is i went out like a light after the shot...
