What is a Secondary collision?
This is where other loose iteams impact the body in a crash
What are some factors that affect the vechile damage
Velocity of the vechile
Mass of the vehicle
Length of stopping distance
what is directly linked to the damage seen in the body
This is the amount of force. The greater the force the more damage you would see
What are the three main paths that patients follow in frontal collisions?
Up and over
Ejection
Down and under
Due to crumple zones in modern cars there is significant less mortality and morbitity however crumple zones can make the crash look worse
What are some injuries that can be seen in Up and over crashes
What are some injuries you can see in ejection crahses
these kinds of crashes need to have a very high index of suspicion.
These can have injuries from hitting the winshield and car parts themselves but it can also be from coming into contact with the iteams outside of the car e.g. road or a tree.
You also need to think about if the pt is going to be ejected far away from the crash itself
what sort of injuries does a down and under crash show
You can also get paper bag conditon (Collapsed lung) People hold their breath and then the impact causes the lungs to pop
What sort of injuries can you see in rear collision impacts
Why do lateral collisions have a higher mortality
What is the main risk of rotational collisions
These can result in more secondary collisions, causing hyperextension and hyperflexion
What differs the index of suscpiction in rollover collisions
This can be ethier minor or servere and it is based on the speed
At high speeds there is significant MOI resulting in mass internal organ damage, crush injuries and possible secondary injuries from loose objects in the car
What influences the injury patterns for a pedestrian involved in a crash
What are some possible injuries that an adult would sustain
What are some injuries that can occur with a pediatric involved in a crash
Kids usually turn towards the car and since they are smaller have a higher impact on the body.
They are also more likley to be thrown from the car or run over by the car
