Similar situation. In my own car. Shots fired. Less that two block. First question? Where's shooter? Second question, where's shootee. Found mid 20 man sitting cross legged on floor holding neck. Very minimal bleeding. No obvious esophageal or tracheal trauma, Patient removed hand from GSW site, still very little blood. Good vitals, patient calm. Other "medic" runs in. The best way I could put it is that he "was all in a tizzy". My query? IV, KVO, NS, monitor vials. Patient remained ambulatory. The other medic, at least one large bore IV 16g, LR, O2 NRB.
Anyone's input?
BTW. The actual shooter was in his 80's. Shooting victim was trying to get his SS check, so the old man shot him. The older man dies two hours later AMI.
