Differentiate between high and low velocity gun shot injuries
Low velocity has the tumble effect where it redirects and causes damage all over
High velocity severely damages everything but also brings in a massive shockwave.
Major blunt trauma case (HBC) what is the first thing you do?
Evaluate all major body systems before you put any effort into outside of animal
Example of vascular injury?
Cast complications sliding up and causing huges damage
Give an example of septic injury?
