1

Cavitation

Pressure waves that can damage nearby structures

2

Multisystem trauma

Significant MOI that causes injuries to more than one body system

3

Kinetic energy

Energy of a moving object

4

Mechanism of Injury (MOI)

How the trauma occured

5

Potential energy

Product of mass, gravity and height

6

Blunt trauma

Result of force to the body that causes injury but does not penetrate soft tissue or internal organs and cavities

7

Penetrating trauma

Injury caused by objects that pierce the surface of the body

8

Work

Force acting over a distance

9

Index of suspicion

Awareness of and concern for potentially serious obvious and underlying injuries

10

Energy can be...

Converted

11

The amount of KINETIC energy that is converted to do work on the body dictates the ______ of the injury

______ energy that is converted to do work on the body dictates the SEVERITY of the injury.

12

Types of motorcycle impacts

Head-on collision
Angular collision
Controlled collision

13

Types of collisions in frontal impact

Car striking object
Passenger striking vehicle
Internal organs strike solid structures of the body

14

Appropriate use of air medical services

Distance to trauma center >25 miles
Traffic/road conditions decrease efficiency/timeliness
Mass-casualty incident

15

Type of velocity a handgun can penetrate

Medium-velocity penetrating injuries may be caused by what type of weapon

16

Compression injury due to motor vehicle collision example

Passenger's head hits windshield, brain continues to move forward until it strikes the inside of the skull, resulting in what type of injury?

17

The most common cause of death from a blast injury

Head trauma is the most common cause of what type of injury?

18

Airbags decrease injury to which body parts?

The chest, face, and head can be protected in a vehicle collision by what item?

19

What type of impacts are commonly referred to as T-bone crashes?

Lateral impacts are commonly referred to as what types of crashes?

20

What is the most common life-threatening event in a rollover

Ejection or partial ejection of the passenger from the vehicle in a rollover is what kind of event?

21

Types of impact associated with a motorcycle crash

Head-on
Controlled

- _______ = Energy that causes injury doubles
- _______ = Energy that causes injury quadruples

25

Whiplash-type injuries are caused by what type of impacts?

Rear-end impacts cause what type of injuries?

26

A compression injury to the anterior portion of the brain and stretching of the posterior portion

Coup-contrecoup

27

Pneumothorax

Air collecting between the lung tissue and chest wall

28

Formula for calculating kinetic energy

KE = 1/2mv^2
...
Kinetic Energy = half of mass by velocity squared

29

Glasgow Coma Scale (GCS) uses what to rate a patient's LOC?

Assessment of...
Eye-opening
Verbal response
Motor response

30

Platinum 10

Limited on-scene time for patients with multisystem trauma

31

Newton's First Law

Inertia and mass...
An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

32

Medical emergency

Illness or condition not caused by an outside force

33

Newton's Second Law

Acceleration...
The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.

34

Newton's Third Law

Action and reaction...
For every action, there is an equal and opposite reaction.

35

Trajectory

Path a projectile takes once it is propelled

36

Blunt trauma

Impact on the body without penetrating soft tissues or internal organs and cavities

37

Drag

Resistance that slows a projectile

38

Tympanic membrane

Eardrum

39

Revised Trauma Score (RTS)

Scoring system used for patients with head trauma

40

Trauma score

Score that incorporates GCS score, respiratory rate, respiratory expansion, systolic BP and capillary refill.

41

Potential energy

Product of mass (weight), force of gravity, and height, mostly associated with the energy for the falling object

42

Factors to consider when evaluating a fall

Height of fall
Surface struck
Party of body hit first, followed by path of energy displacement

43

Information gathered when determining the MOI of a motorcycle crash

Motorcycle deformity
Side of most damage
Distance of road skid
Deformity of stationary objects/other vehicles
Extent and location of deformity in helmet

44
