Term
| Describe the relationship of mass and velocity to kinetic energy, including the relative contribution of each to the amount of kinetic energy |
|
Definition
| double mass equals double the amount of force, while velocity can square the amount of kinetic energy |
|
|
Term
| Explain the effects of acceleration and deceleration on kinetic energy and the potential for injury |
|
Definition
| acceleration can increase the kinetic energy of an object and thus cause more damage |
|
|
Term

|
Definition
| you have the vehicle crash, the body crash, and organ collision |
|
|
Term
| List situations in motor vehicle collisions in which you should have a high index of suspicion for critical injuries |
|

|
|
Term
| Explain the typical patterns of injury associated with each of the following types of motor vehicle impacts: Frontal |
|
Definition
| Frontal injuries breed abdominal injuries, chest bones and soft tissues, the heart and lungs are compressed and sheared, lungs can rupture, and the face head and neck can be injured from colliding with the windshield. |
|
|
Term
| Explain the typical patterns of injury associated with each of the following types of motor vehicle impacts: Rear |
|
Definition
| You will find whiplash injuries and anterior spinal ligaments are often stretched or torn. |
|
|
Term
| Explain the typical patterns of injury associated with each of the following types of motor vehicle impacts: Lateral |
|
Definition
| You may find lots of neck injuries because laterally the muscles arent as strong, injuries can occur from the door striking the chest and abdomen, also find fractures of the pelvis and upper femur |
|
|
Term
| Explain the typical patterns of injury associated with each of the following types of motor vehicle impacts: Rotational and rollover |
|
Definition
| multisystem trauma is common, ejection is common if not restrained, finally crushing injuries are evident |
|
|
Term
| Explain the typical patterns of injury associated with each of the following types of motor vehicle impacts: Vehicle adult pedestrian |
|
Definition
| with adults its common to find injuries to the lateral or back side because adults tend to turn from the object |
|
|
Term
| Explain the typical patterns of injury associated with each of the following types of motor vehicle impacts: Vehicle child pedestrian |
|
Definition
| very common to find frontal injuries because the child will turn toward the oncoming object |
|
|
Term
| Discuss the effects of the use of restraint systems in motor vehicle collisions |
|
Definition
| has five points of restrained and prevents the body from moving to far forward |
|
|
Term
| Explain the typical pattern of injury associated with motorcycle collisions |
|
Definition
| head on impact collision, angular impacts, or ejection injuries |
|
|
Term
| Describe factors that affect the pattern and severity of injury produced in falls |
|
Definition
| The height and whether or not the person locked out there legs on the fall |
|
|
Term
| Compare and contrast injury patterns produced by low, medium, and high velocity penetrating mechanisms of injury |
|
Definition
| low impact causes injuries to the direct area, |
|
|
Term
| Describe the mechanism by which blast injuries produce injury |
|
Definition
| the primary (blast wave), secondary (fragmentation damage), and tertiary (impact against something else) |
|
|
Term
| Describe the principles of care for multisystem trauma patients |
|
Definition
| Respond quickly, assess life threatening injuries, manage life threats, and promptly prepare for transport |
|
|
Term
| Explain the term golden period and identify indications for an on scene time of 10 minutes or less when caring for trauma patients |
|
Definition
| The amount of time a patient has to increase chance of survival. Most emts should be off scene in ten minutes and en route to the hospital |
|
|
Term
| differentiate the characteristics of different level trauma centers |
|
Definition
| Level I is the highest with 5 being the lowest |
|
|
Term
| Identify patients who meet trauma triage criteria for transportation to a trauma center |
|
Definition
| airway occlusion, respiratory rate <10 or >29, inadequate tidal volume, hypoxia, respiratory failure, suspected skull fracture, flail chest, suspected pneumo, pelvic fracture, two or more proximal long bone fractures, crushed or mangled exremity, uncontrolled hemorrhage, suspected internal hemorrhage, shock, significant external blood loss, glasgow coma of less than 14, altered mental, seizure, sensory or motor deficit, penetrating injuries to head neck or anterior, amputation of an extremity proximal to the finger, trauma in a patient with a significant medical history, multisystem trauma, open or depressed skull fracture, suspected brain injury, paralysis |
|
|
Term
|
Definition
| a cavity formed by a pressure wave resulting from the kinetic energy of a bullet traveling thorough body tissue, also called pathway expansion |
|
|
Term
|
Definition
| how energy is transferred to the human body by the forces acting on it |
|
|
Term
|
Definition
| the factors that slow a projectile |
|
|
Term
|
Definition
| the breaking up of a bullet into small pieces on impact |
|
|
Term
|
Definition
| the energy contained by an object in motion |
|
|
Term
|
Definition
| the branch of mechanics dealing with the motions of material bodies |
|
|
Term
|
Definition
| the science of analyzing mechanism of injury |
|
|
Term
|
Definition
| the factors and forces that cause traumatic injury |
|
|
Term
|
Definition
| the size and shape of a bullets point of impact |
|
|
Term
|
