What are the four collisions? - Answer-1. The vehicle
2. The occupants
3. The internal organs
4. The secondary impacts
Energy transmission in a rollover depends on? - Answer-
Deceleration distance
Energy is dissipated over the distance of the roll and
whether or not the occupants are restrained
Car vs pedestrian injuries depend on? - Answer-Point of
contact with the care
Height of hood & bumper
Size & weight of vehicle
Height of patient
Direction patient was facing when struck
,2|Page
What is the most common mechanism of injury in all age
groups? - Answer-Falls
Factors predicting fall injuries are? - Answer-Fall height
(velocity)
Landing surface (deceleration distance)
Point of impact on the body
Wound ballistics- permanent cavity - Answer-Cavity is the
a function of the size, shape, and characteristic of the
missile (mass)
For every second of fall time, speed increases by? -
Answer-Speed increases by approximately 20 MPH
Define Shock? - Answer-A state in which cellular oxygen
demand exceeds supply
When the cost of tissue oxygen is higher than the body
can pay, an oxygen debt develops.
Types of shock per TCAR? - Answer-Pumps-Site of defect
heart
,3|Page
Pipes- site of defect is artery, veins or capillaries
Fluid-intravascular, interstitial or intracellular
VS in shock? - Answer-Narrow pulse pressure
Tachycardia
Low CO
How many ATP molecules are produced with oxygen &
glucose? - Answer-32 ATP molecules
How many ATP molecules are produced without oxygen? -
Answer-2 ATP molecules
Normal pH? - Answer-Refernce range is 7.35-7.45, but
actual normal range is 7.38-7.42
What is the footprint of shock? - Answer-Lactic Acidosis
What 2 things affect the amount of oxygen availalbe to the
cells? - Answer-Temperature & pH, which is the
oxyhemoglobin dissociation curve
, 4|Page
Oxyhemoglobin dissociation shift to the right? - Answer-
Acidosis, elevated temp
More oxygen available to the cells
Oxyhemoglobin dissociation curve shift to the left? -
Answer-Hypothermia, alkalosis
Less oxygen available to the cells
H & H is a measure of ? - Answer-It is a measure of
hemodilution rather than blood loss.
What are the hormonal responses to shock? - Answer-
Promote body water retentions by secretion of ADH &
activation of RAAS
