There was a horrific traffic accident and you run to help the victims. You feel a pulse from his carotid artery ,however the medic comes along and gets no blood pressure as he measures it from the arm. He claims the victim is dead. You think which of the following?

Medic is not correct since it is the difference between heart rate and blood pressure that determines life. No heart rate only means tha the sympathetics have stopped vasoconstricting the blood vessels.
B
Medic is correct since it is common to not have a blood pressure of 120/80 and no pulse due to stress as was discussed in class.
C
Medic is incorrect since there is a pulse. This means the person is still alive.
D
Medic is correct since there is no blood pressure there is no life.
