Is There a Complication of Choking on Steak?

If someone choked on their steak sandwich and then arrested, ther c t can in the emergency department shows tonsulr herneation. Probably someone who's brain dead. If anyone's ever watched a donation, after cartia das, usually the heart is the last thing to go right. Usually there's some profound hypoxemia going on before the heart arrests. So not a good mechanism. How about other confounders though? So we're not going to put all the weight on the mechanism. What other factors, on history, and more importanty on clinical exam and laboratory investigations am i going to be careful about?
