arterial air embolism
Air bubbles in the arterial blood vessels.
blunt trauma
An impact on the body by objects that cause injury without penetrating soft tissues or internal organs and cavities.
cavitation
A phenomenon in which speed causes a bullet to generate pressure waves, which cause damage distant from the bullet's path.
coup-contrecoup injury
Dual impacting of the brain into the skull; coup injury occurs at the point of impact; contrecoup injury occurs on the opposite side of impact, as the brain rebounds.
deceleration
The slowing of an object.
Resistance that slows a projectile, such as air.
drag
An evaluation tool used to determine level of consciousness, which evaluates and assigns point values (scores) for eye opening, verbal response, and motor response, which are then totaled; effective in helping predict patient outcomes.
Glasgow Coma Scale (GCS) score
Awareness that unseen life-threatening injuries may exist when determining the mechanism of injury.
index of suspicion
The energy of a moving object.
kinetic energy
The way in which traumatic injuries occur; the forces that act on the body to cause damage.
mechanism of injury (MOI)
Emergencies that require EMS attention because of illnesses or conditions not caused by an outside force.
medical emergencies
Trauma that affects more than one body system.
multisystem trauma
Injury caused by objects, such as knives and bullets, that pierce the surface of the body and damage internal tissues and organs.
penetrating trauma
The product of mass, gravity, and height, which is converted into kinetic energy and results in injury, such as from a fall.
potential energy
Any object propelled by force, such as a bullet by a weapon.
projectile
Pulmonary trauma resulting from short-range exposure to the detonation of explosives.
pulmonary blast injuries
A scoring system used for patients with head trauma.
Revised Trauma Score (RTS)
The path a projectile takes once it is propelled.
trajectory
Emergencies that are the result of physical forces applied to a patient's body.
trauma emergencies
A score that relates to the likelihood of patient survival with the exception of a severe head injury. It calculates a number from 1 to 16, with 16 being the best possible score. It takes into account the Glasgow Coma Scale (GCS) score, respiratory rate, respiratory expansion, systolic blood pressure, and capillary refill.
trauma score
The eardrum; a thin, semitransparent membrane in the middle ear that transmits sound vibrations to the internal ear by means of auditory ossicles.
tympanic membrane
The product of force times distance.
