1- Trauma- Airway And Assessment Flashcards
Kinematics equation and what has the most effect
K = 1/2Mass x Velocity^2
Velocity/speed has the biggest effect
What are the 3 types of collisions in a car vs object crash
1- Car vs Object
2- Body vs interior of vehicle
3- Organs vs body interior
What are secondary collisions in a vehicle collision
Contents of the car striking the victim
What are the 5 types of vehicle collisions from most to least common
1- Rotational 38% 2- Frontal 32% 3- Lateral 15% 4- Rear end 9% 5- Rollover 6%
What is down and under caused by and what happens
Frontal collisions
Knee, femur, hip fractures and dislocations from sliding under the steering column and hitting the dash
What is up and over caused by and what happens
Frontal collisions
Chest injuries, head injuries or ejection
What type of collision has a high incident of deaths
Lateral collisions
Injuries resulting from Lateral collisions
- Extremity, rib fracture, on side of impact
- Cspine and aorta injury
Explain paper bag syndrome
Rapid inhale right before impact, chest hits interior and punctures inflated lung
What is a main concern of rotational impact
Multiple impacts but less injury that vehicle suggests
3 step process of a rear end collision
1- Head snaps back, neck extends
2- Head snaps forward, neck flexes
3- Brain also moves inside the skull
Injury patterns from rollover crashes are
Unpredictable
Most life threatening injury from a vehicle collision is
Ejection
Proper position for a lap belt
Across pelvic girdle
Injuries from improper lap belt placement
T-12, L-1 and L-2
Injuries from improper shoulder harness position
Chest and head injuries
At what age can kids ride in the front seat
13 y/o
How is an airbag deployed
Electrical charge of impact
What from an airbag can cause what problem
Chemicals can irritate eyes and mouth
4 types of motorcycle collisions
- Frontal
- Angular
- Sliding
- Ejection
Common injury from frontal motorcycle collision
Bilateral femur fracture
Common injury from angular motorcycle collision
Trapped lower extremity
Common injury from a sliding motorcycle collision
Abrasions and minor fractures
3 types of motorcycle ejections
- Bike v Object
- Rider v Object
- Rider v Ground
What’s the main concern with sports injuries
C-spine
When should you remove a helmet (2)
- Too big/loose
- Inaccessible airway when needed
3 impacts of pedestrian accidents
1- Vehicle hits body
2- Body hits vehicle
3- Body hits ground
What is related to injury potential of falls
Height
At what height is a fall considered significant
3x the persons heights
What things should be considered with a fall (4)
- Height
- Surface
- Body part that hit first
- Path of energy displacement
