He has poor dentition, bad breath, and smells like a macro-brewery. You manage to extract the patient from your coat and have him led to a stretcher as you make a quick escape to see a different patient. While the patient is being placed on the stretcher, he becomes very excited, and short of breath. He has a generalized seizure lasting a few seconds, and suddenly stops breathing. You immediately stop whatever you were doing, and rush back to intubate this fellow.
Intubation is messy but accomplished without difficulty.
A foley is placed. The cardiac monitor shows a narrow complex sinus tachycardia. A chest x-ray, and, a drug screen, and of course an alcohol level are requested. In the meantime, a ventilator is brought. Although this patient will probably need to be admitted, you await the laboratory, hoping that his alcohol level is closest to your guess.
