I am not a medical professional. Nervous system was instantly affected and his body flung to the so callev teapot arms position. You are VERY unlikely to survive a shot like that under the BEST care in the world given that as we all can see, no amount of pressure on the wound can stop the blood loss. The last 5-6 seconds of your life are just a fade to black, pain is no longer a concept for your brain, you got quite literally unplugged and your body never knows what happened.
