Becca's Mom~ Emily just had a bronch and endoscopy done at the same time last week. She did very well with the anesthesia (propofol.) Her o2 levels were on the low side immediately following but came up nicely with a short period on o2, and then when they dropped again a bit on room air, a short period of just blow-by o2+albuterol.
They did not induce a 'deep' level of anesthesia for either procedure and she never stopped breathing on her own. Her cough was more frequent/productive the rest of that day and night but she's been fine. (She has a baseline cough anyway.)
This procedure was the 8th time she's been sedated and I still worry each time... that is definitely normal.
