Shock Flashcards
inadequate tissue perfusion
Shock or Hypoperfusion
Poor tissue perfusion (shock) is typically due to one or more of the following basic etiologies:
- inadequate volume
- inadequate pump function
- inadequate vessel tone
Cause of whole blood loss
bleeding
Cause of loss of plasma volume
diarrhea., burns, excessive urination, increased capillary leakage & excessive vomiting.
If the pt. lost whole blood from hemorrhage, this pt. would benefit most from administration of
packed red blood cells and fluids
A pt. who is in shock from excessive diarrhea or burns would benefit most from administration of
fluids,
because no red blood cells were lost, only large amounts of water & some electrolytes
May result from an injury to the heart that reduces its ability to generate contractions strong enough to push the blood forward through the body (no blood volume loss) This shock is due to:
Inadequate pump function
A mechanical condition where the heart may be compromised from a collection of blood in the pericardial sac
Pericardial tamponade
The pt. has not lost any blood volume, however, there is no longer enough intravascular blood volume to fill the vascular space because of the increase in vessel size. This shock is due to:
Inadequate vessel tone
Pt. has lost blood volume due to hemorrhage, diarrhea, burns, excessive urination etc. This shock is due to:
Inadequate volume
shock that is caused from a low blood volume
hypovolemic shock
hemorrhage shock refers to
the loss of whole blood
nonhemorrhageic shock refers to
fluid loss from burns & dehydration
Shock that is associated with a decrease in intravascular volume caused by massive systemic vasodilation and an increase in capillary permeability
distributive shock
Shock that is caused by ineffective pump function of the heart (CHF, heart attack)
cardiogenic shock
