Trauma Overview: The Trauma Patient and the Trauma System
Show Answers:

  1. Kinetics of Trauma
    • The science of analyzing mechanisms of injury
    • Helps you to predict the kind and extent of injuries as a basis for your priority decisions regarding continuing assessment, care, and transport
  2. Kinetics
    The branch of mechanics dealing with the movements of bodies, so understanding kinetics is helpful in understanding mechanisms of injury and trauma
  3. Law of Inertia
    A body at rest will remain at rest, and a body in motion will remain in motion, unless acted upon by an outside force
  4. Trajectory
    The path or motion of a projectile during its travel
  5. Dissipation of Energy
    The way energy is transferred to the human body from the force acting on it
  6. Drag
    The factors that slow a bullet down, such as wind resistance
  7. Profile
    The impact point of the bullet
  8. Cavitation
    The cavity in the body tissues formed by a pressure wave resulting from the kinetic energy of the bullet
  9. Fragmentation
    A bullet that breaks up into small pieces or releases small pieces upon impact increases the body damage
  10. Primary Phase Injuries
    • Due to the pressure wave of the blast
    • Primarily affect the gas-containing organs
  11. Secondary Phase Injuries
    • Due to flying debris propelled by the force of the blast, or blast wind.
    • Lacerations, impaled objects, fractures, and burns
  12. Tertiary Phase Injuries
    Occur when the patient is thrown away from the source of the blast
  13. Level I- Regional Trauma Center
    Can manage all types of trauma 24 hours a day, 7 days a week
  14. Level II- Area Trauma Center
    • Can manage most trauma with surgical capabilities 24 hours a day, 7 days a week
    • They are capable of stabilizing more specialized trauma patients ad then transferring them to a level I center
  15. Level III- Community Trauma Center
    • Has some surgical capability and specially trained emergency department personnel to manage trauma
    • Focuses on stabilizing the seriously injured trauma patient and then transferring to a higher-level center
  16. Level IV- Trauma Facility
    Small community hospital in a remote area capable of stabilizing seriously injured trauma patients ad then transferring them to a high-level trauma center
