Wow, I didn’t think surgeons were allowed to smoke around all that oxygen equipment.

Seriously, though, please explain to me how a surgeon’s mask protect’s a patient from breathing in viruses the surgeon doesn’t know he has when the patient’s mouth and nose are well-covered by mask used to give him the knockout gas.

Back when I rode an ambulance, our medical director told us to stick anyone we suspected of being contagious on a non-rebreather mask.

Never been in an operating room except as a patient or to observe, but I know they're super concerned about infection, especially staph.
