What roles are vital to a trauma team - ---✔✔✔ANSWER----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 - ---✔✔✔ANSWER----dynamic
interdependent
adaptive
common goal
COMMUNICATION
,COOPERATION
COORDINATION
Kinematics - ---✔✔✔ANSWER----study of energy transfer as it applies to
identifying actual or potential injuries
Biomechanics - ---✔✔✔ANSWER----general study of forces and their
effects
mechanism of injury - ---✔✔✔ANSWER----how external energy forces in
the environment are transferred to the body
Newtons 3 laws - ---✔✔✔ANSWER----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 - ---✔✔✔ANSWER----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 - ---✔✔✔ANSWER----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 - ---✔✔✔ANSWER----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 - ---✔✔✔ANSWER----1. blunt trauma-
falls; mvc; trauma
2. penetrating- stabing; GSW
, 3. Thermal
4. Blast Trauma- bomb
deceleration vs acceleration forces - ---✔✔✔ANSWER-----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 - ---✔✔✔ANSWER---
--point of impact on the body
-type of surface that is hit
-tissues ability to resist injury (bone is less flexible)
-pt pushed = more acceleration
3 impacts in a MVC - ---✔✔✔ANSWER----1. vehicle hits another object:
occupant = acceleration
2. occupant collides with interior of vehicle: internal organs continue
3. internal structure collide with body
