Yes, pre-oxygenation buys you more time for apnea if you have airway difficulty, but it isn't a lapse in safety if it doesn't occur. So if there had been airway difficulty, it would have been a lapse in safety but since there wasn't, it was okay. I guess that doesn't make sense to me but as long as I don't have to chart it, I'm okay with it. I guess what really freaked me out about this whole experience from a safety point of view is that apparently no one did a sensory or motor check on the patient before the surgery started either. She clearly felt pain and was able to move her arm when she tried to get off the table. After the patient was out the surgeon basically tore the CRNA a new one about it. I guess I feel bad for the patient - somehow I let her down. She was really scared and now the chart doesn't even reflect what she went through. I guess I'm being too soft. I suppose after a few months I will get over it. Thanks for the responses.
