Where is he shot at?
It's probably obvious, if it's a suicide..
They taught us how to handle this in our "school for rangers"..
Since PGC and BOF has to initiate a full investigation into all hunting accidents, on state or private land, they would have run of the scene over state police. Unless there is a crime.
Don't step in the blood, clear any non ems/pd personnel out.. that means firemen too. Don't move the victim, don't move the gun, don't touch anything other than the victims neck for a pulse. If death is obvious, or condition is not compatible with life, don't even try to get them back. It's not worth keeping someone on a respirator w/ their memory and quality of life dripping out a hole in their cranium.
Check for pulse > if there is one, take his hand off the gun. If there is no pulse > listen w/ a scope for 60 seconds and write down the time b/c he's a DOA.
If it's a DOA, clear the area, only cover them if it's snowing. Walk in the steps you came in with. Note any steps off other than yours, and the victims. Note anything suspicious, etc. Take polarides if possible.
200 Yards off the roadway is considered a woods rescue. So we don't start CPR unless it's a drowning that JUST happened. In wilderness EMS, CPR is a no no. AED is also a no no. You can't do CPR on someone that is in a stokes basket, it's just not possible, you'll end up dropping the patient, or injuring someones back.
If the idiot has shot himself in the leg, and he has a pulse.. Don't rewarm till you have a pressure dressing on it. In this case, Hypothermia is your friend.
Apply a 12x30 to each exit and entrance. Apply an inflatable splint, and fill it to the max, clamp the hose w/ a hemostat. Back board him, stokes him, apply O2, wrap a hot pack around the oxygen hose, or use warm humidified water. transport. Fly him if possible. Special case > OMC>Consider MAST for shock; two IV's NS/LR 1000 bolus; ekg; dextrose/thiamine/naxalone; keep the epi and atropine on hand in case he arrests; third large bore IV; rapid infuser w/ hot packs; 10 mcg/Dopamine; intubate; place the pacer pads on just in case; field foley (lots of fluids given)
