1

Trauma

Primary cause of death in ages between 1-44 years old
-occurs when external source of energy affects the body beyond its ability to sustain and dissipate it

2

Mechanical energy

Energy from motion-KINETIC ENERGY

3

Potential energy

Energy an object can have when stationary

4

Chemical Energy

Energy released as a result of a chemical reaction and can be found in an explosive or an acid

5

Electrical Energy

Form of high voltage

6

Barometric Energy

Sudden radical changes in pressure

7

Biomechanics

Study of a living organism using tools

8

Kinetics

Study of speed, mass, direction of force, and physical injury

9

Organs

Organs that have gas inside can be easily compressed

10

Types of injury

Depend on force and energy delivered

11

Blunt Trauma

When skin is not broken and the force and energy is made to dissipate

12

Duration of force application

Affects trauma because rapidly applied amounts of energy are less tolerated than an identical amount over a longer period of time

13

Impact resistance of body parts

Determined by what is inside the organs (gas, liquid, solid)

14

Index of suspicion

Suspecting an injury is present

15

Velocity

Distance an object travels per unit time

16

KE

=m/2XV2

17

Phases of MVC

First: deceleration of vehicle
Second: deceleration of occupant
Third: deceleration of organs
Fourth: secondary collision
Fifth: additional impacts

18

Head on Impact

Brain Injury
Scalp
Spinal
Chest
Pneumo
Femoral
Aortic tear
-less survivors

19

Rear end

Whiplash bleeding inside skull
-more survivors

20

Abrupt deceleration forces

Sudden stop
-shearing, avulsing, rupturing of organs
-chest vulnerable to aortic injury
-blunt abdominal injuries

21

Organs commonly affected

Kidneys, small intestine, liver, large intestine, pancreas and spleen

22

Lateral Impact

Pelvis and chest

23

Rotational or quarter panel impacts

Forward and diagonal Impact
-three angled seatbelts

24

Rollovers

May be ejected without seatbelt
-ejection increased death by 25%
- 1 in every 13 people in ejection sustain major cervical spine damage

25

Airbags

Will not deployed unless hit from the front and won't if hit lateral quarter
-abrasions to face, arms and hands
-cornstarch used in airbags to load
-pediatrics can be killed with airbag deployment

26

Motorcycle Crashes

Helmets transmit forces to the spine
4 types of crashes:
Head on- hit and continue forward until stopped by outside force yielding bilateral femur or tibia fractures
Angular Impact- direct crushing injuries to lower extremity between object and motorcycle
Ejected rider- laying down or sliding results in road rash

27

MOI's

First: auto strikes body
Second: body hits hood
Third: body hits grund

28

Waddell Triad

Bumper hits pelvis, chest and abdomen hit grille, head strikes vehicle and ground

29

Don Juan Syndrome

Jumping down to ground
Energy transferred to heel, legs, pelvis and chest
T12-L1 and L2
-children younger than 3 have fewer injuries from falls greater than three stories than children and adults

30

Stab Wounds

Low versus high velocity.
Depends on length, blade, and motion of weapon
