Vocabulary (12)

Mechanism of injury (MOI)
The force or event that caused a patient's injuries; used to anticipate the patterns and severity of trauma.
Kinematics
The study of how energy is transferred from one object to another — applied to predicting injury patterns in trauma.
Blunt trauma
Injury caused by force that does not penetrate the skin — e.g., motor-vehicle collisions, falls, assault with blunt objects.
Penetrating trauma
Injury caused by an object that breaks the skin and enters tissue — e.g., gunshot or stab wounds.
Golden Period
The first hour after major trauma during which definitive surgical care most strongly improves outcomes.
Platinum 10 minutes
The first 10 minutes of EMS patient contact in major trauma — the window during which critical interventions and packaging should be done.
Newton's first law of motion
A body in motion stays in motion until acted on by another force — explains why occupants continue forward in a sudden vehicle deceleration.
Cavitation
Tissue displacement and damage along the path of a projectile, extending beyond the visible wound track.
Trauma center
A hospital with specialized resources for severely injured patients, designated Level I (highest capability) through Level V.
Triage
Sorting patients by severity and likelihood of benefit to allocate care when resources are limited.
Index of suspicion
Clinical anticipation of specific injuries based on mechanism, even when external signs are limited.
Field triage criteria
Evidence-based decision scheme used by EMS to determine which trauma patients should be transported to a trauma center.

Sequence practice (2 puzzles on Quiz Me)

Trauma scene to handoff priorities

Order the EMT's macro priorities for a major trauma patient.

  1. Scene safety and BSI
  2. Identify mechanism and number of patients
  3. Primary survey with simultaneous critical interventions (catastrophic hemorrhage, airway, breathing)
  4. Make the load-and-go decision early
  5. Brief secondary exam and ongoing reassessment in transit
  6. Activate trauma center; structured handoff at arrival
CDC field triage decision steps (simplified)

Order the simplified CDC field triage decision steps from most to least urgent.

  1. Step 1 — Physiologic criteria (vital signs, GCS) abnormal
  2. Step 2 — Anatomic criteria (penetrating injury, flail chest, two or more long-bone fractures, paralysis)
  3. Step 3 — Mechanism criteria (high-energy MOI)
  4. Step 4 — Special considerations (age, anticoagulation, pregnancy, burns)
