✓ The patient
Team leader-organize team/empower members
core team-technical skills- airway/vascular access
contingency and support survices- RT
Characterisitcs of an effective team

Kinematics
✓ study of energy transfer as it applies to identifying actual or potential
injuries
Biomechanics
✓ general study of forces and their effects
mechanism of injury
✓ how external energy forces in the environment are transferred to the
body
Newtons 3 laws
✓ 1. an object in motion will stay in motion
2. force = mass x acceleration
3. for every action there is an equal and opposite reaction
5 forms of energy that exist

✓ 1. Mechanical- energy transfer from one object to another in form of
motion
2. thermal-heat transfer from environment to host
3. chemical- heat energy trnsfer from active chemical substances such as chlorine, drain
cleaner, acids
4. electrical- energy transfer from light socket
5. radiant- energy transfer from blast sound waves, nuclear, rays from the sn
eternal forces in trauma
✓ 1. deceleartion- falls and collison = sudden stop
2. acceleration- sudden onset of motion- hit by a car
3. compression- hit stationary objects; bullets; blast forces

internal forces of energy in trauma
✓ stress- internal force that resists external force
solid organs good at pressure wave energy
air organs better at shear forces
4 main types of traumatic injury
✓ 1. blunt trauma- falls; mvc; trauma
2. penetrating- stabing; GSW
3. Thermal
4. Blast Trauma- bomb
deceleration vs acceleration forces
✓ -Deceleration: injury that occurs as pt slows down
acceleration injury: injury that occurs as a result of other parts of the body stopping before
the organs do (concussion; shearing of aorta)
environment and pathophysiology when MOI is a fal
