Chapters 15 (490-507) and 27 Flashcards
Shock
Inadequate tissue perfusion, aka hypoperfusion
Hypovolemic Shock
Shock caused by the loss of blood or fluid from the intravascular space resulting in a low blood volume
Distributive Shock
Shock associated with a decrease in intravascular volume caused by massive systemic vasodilation and an increase in capillary permeability
Cardiogenic Shock
Poor perfusion resulting from an ineffective pump function of the heart
Obstructive Shock
A poor perfusion state resulting from a condition that obstructs forward blood flow
Hemorrhagic Hypovolemic Shock
Shock from the loss of whole blood from the intravascular space, aka just hemorrhagic shock
Nonhemorrhagic Hypovolemic Shock
Shock caused by loss of fluid from the intravascular space with RBC’s and Hb’s remaining within the vessels
Burn Shock
A form of Nonhemorrhagic hypovolemic shock resulting from burn injury
Anaphylactic Shock
Distributive shock in which chemical; mediators cause massive systemic vasodilation and permeable, leaking capillaries
Septic Shock
A type of distributive shock caused by an infection that releases toxins into the blood
Neurogenic Shock
A type of distributive shock that results from massive vasodilation, aka vasogenic shock
Compensatory Shock
Stage of shock in which a cascade of organ and gland stimulation and hormones increases BP, restores arterial wall tension, and maintains a near normal BP and perfusion of vital organs
Decompensatory Shock
Stage of shock in which the bogy’s compensatory mechanisms are no longer able the maintain a BP and perfusion of vital organs
Irreversible Shock
Stage in which interventions cannot prevent a the advance of shock to death
Mechanism of Injury (MOI)
The factors and forces that cause traumatic injury
Kinetics of Trauma
The science of analyzing mechanism of injury
Kinetics
The branch of mechanics dealing with the motions of material bodies
Kinetic Energy
The energy contained by an object in motion
Trajectory
The path of a projectile during its travel, may be flat or curved
Dissipation of Energy
How energy is transferred to the human body by the forces acting on it
Drag
The forces that slow a projectile
Profile
The size and shape of a bullets point of impact
Cavitation
A cavity formed by a pressure wave resulting from kinetic energy of a bullet traveling through body tissue, aka pathway expansion
Fragmentation
The breaking up of a bullet into small pieces on impact
