Energy
The product of mass (weight), force of gravity, and height
Potential Energy
The second leading cause of trauma death in the US after burn trauma
Penetrating Trauma
Injuries due to the blast wave itself (hallow organs are most susceptible to pressure changes)
Primary Blast Injury
* scene size-up
* primary assessment
*history taking
* secondary assessment
* reassessment
Patient Assessment
A phenomenon in which speed causes a bullet to generate pressure waves, which cause damage distant from the bullets path
Cavitation
For ever action, there is an equal and opposite reaction
Newtons Third Law
Refers to multiple traumatic injuries involving more than one body system, such as head and spinal trauma, chest and abdominal trauma, or chest and multiple extremity trauma
Multisystem Trauma
Due to the impact with another object
Tertiary Blast Injury
A comprehensive regional resource that is a tertiary care facility
Level 1 Trauma Center
The energy of a moving object
Kinetic energy
Its not so much the speed in itself that causes injury, but the sudden change in velocity over time.
Newtons Second Law
The car is typically struck above its center of gravity and begins to rock away from the side of impact. Causes lateral whiplash
Lateral Crash/T-Bone crash
Consequences of contaminants release by the explosion
Quinary Blast Injury
deformities, contusions, abrasions, puncture/penetration, burns, tenderness, lacerations, swelling
DCAP-BTLS
Trauma that affects more than one body system
Multisystem Trauma
Doubling the objects mass doubles the objects total kenetic energy
Velocity
The result of the brain striking the opposite side of the skull after it rebounds from the first impact
Coup-Countercoup
Due to missiles being propelled by blast forces
Secondary Blast Injury
Massive Hemorrhage, Airway, Respirations, Circulation, Head injury/hypothermia
MARCH
Pulmonary trauma resulting from short-range exposure to the detonation of explosives
Pulmonary Blast Injuries
1/2 Mass x Velocity^2
Kinetic Energy
Sudden or rapid deceleration of the heart and the aorta within the thoracic cavity, which may rupture the aorta and cause fatal bleeding
Traumatic Aortic transection or rupture
Collateral injuries such as burns, crush injuries, and toxic inhalation
Quaternary Blast Injury
* Dangerous MOI
* Decreased LOC
* Threats to ABC's
Life threatening Injury
A scoring system used for patient's with head trauma
Revised Trauma Score (RTS)
