,What tools can be used to promote 1. SBAR: Situation, Background,
Assessment, communication within a team member? Recommendations-To
provide a framework for

you feel, Suggest alternatives and seek agreement,
state Consequences in terms of impact on
performance goals-Used in conflict management,
paraphrasing the other person's comments is an
important technique that should be done throughout
the DESC support
3.CUS: I am Concerned, I am Uncomfortable, This is a
Safety issue/I am Stressed-Used to "stop the line" if a
team member senses or discovers an essential safety
breach
Kinematics The study of energy transfer as it applies to
identifying actual or potential injuries
Biomechanics The general study of forces and their effects
Mechanism of Injury How external energy forces in the
environment are transferred to the body
Newton's First Law of Motion A body rest will remain at rest, and a body in
motion will stay in motion
Newton's Second Law of Motion Force = mass x acceleration
Newton's Third Law of Motion For every action, there is an equal and opposite reaction
Law of Conservation of Energy Energy can neither be created nor destroyed, but can
change
form
,Describe how Newton's Laws of Motion and -1st: weight and speed are reasonable
substitutions for mass the Law of Conservation affect energy and velocity, higher mass
and/or higher speed delivers greater transfer in traumatic injury, and give an energy
example -2nd: an object's velocity changes when it is
subjected to an external force; heavier objects
require more force to accelerate (or decelerate)
them
-3rd:
-Conservation:
Ex: pot vs. child
-1st: the force of gravity holds the pot on the flat
stovetop until energy is transferred to the pot, such
as by a toddler, grabbing the handle.Once the pot is
in motion, it will sustain its motion until interrupted
by another force. As the pot strikes the child in the
head, the strength of bone imposes a force of
resistance upon impact, thereby changing the
directional path of the pot. The stationary head stays
in a fixed position until a volume of energy adequate
to move the head is transferred to it. This concept of
movement-energy transfer- countermovement
applies to all mechanical traumas
-2nd: the pot continues to fall at a steady rate unless
it is acted on by an outside force (a hand pushing it
out of the way or catching it)
-3rd: the transfer causes a redirection of the pot
and movement of the head, as well as energy
absorption causing anatomic changes to the tissue
that received the energy transfer
-Conservation: energy is not created, nor it is
destroyed at the site where the pot impacts the head.
Instead, energy is transferred from the kinetic
(moving) object to the object being impacted
What are the five forms in which energy 1. Mechanical: energy transfer form one object to
another in exist? the form of motion
2.Thermal: energy transfer of heat in the
environment to the host
3.Chemical: heat energy transfer from active
chemical substances, chlorine, drain cleaner,
acids, or plants
4. Electrical: energy transfer from light socket, power
lines, or lightning
5.Radiant: energy transfer from blast sound
waves, radioactivity such as a nuclear facility,
or rays of the sun
, Differentiate between internal and external External forces:
forces of energy transfer in the context of -Can be exerted on the body by deceleration,
acceleration, trauma compression forces
-Deceleration forces include those applied in falls
and collisions where injuries are cause by a sudden
stop in the body's motion
-Acceleration forces are not as common as
deceleration forces and result from a sudden and
rapid onset of motion, like a parked car that is hit y
vehicle traveling at the high rate of speed
-Compression force is an external force applied at
time of impact, like stationary objects-dashboards or
steering wheels that collide with or push up into a
person. Objects in motion- bullets, stabbing, bats,
balls, fists and feet, or heavy falling objects
-Blast forces
Internal forces:
-Stress describes the internal force that resists the
applied external force
-Stress is exerted on the body as tissues and organs
change their dimensions
-Body tissues respond differently to energy impact, and
the capacity to withstand energy transfer is based on
the characteristics, combined with biomechanics and
MOIs
-The strength of bone varies and can be augmented
by adjacent muscle systems
-Solid organs tolerated pressure-wave energy better
than air- filled organs
-Air-filled organs can often resist shear forces
better than solid organs
