exam 1 part 2 Flashcards
4 types of shock
Cardiogenic
Hypovolemic
Distributive
Obstructive
common theme between all shocks
hypoperfusion
Due to: Systolic or Diastolic dysfunction of the heart, dysrhythmias, or structural factors
Congestive HF : issue with the myocardium
cardiogenic shock
tx for cardiogenic shock
: Nitrates, inotropes (dobutamine), diuretics, Beta Blocker
External loss of whole blood or loss of other bodily fluids
d/t either hemorrhage from trauma, surgery, or a GI bleed
Other: vomiting, diarrhea, excessive diuresis, DI, DM
absolute hypovolemic shock
Pooling of blood or fluids, fluid shifts, internal bleeding, massive vasodilation
d/t: Bowel obstruction, burns, ascities, fx of long bones, ruptured spllen, hemothorax, severe pancreatitis
Massive vasodilation d/t sepsis
relative hypovolemic shock
only shock with bradycardia
neurogenic shock
loss of sympathetic tone- massive vasodilation- hypotension, bradycardia
neurogenic shock
what is neurogenic shock defined as
spinal cord injury and/or disease at or above T5
tx for neurogenic
Vasopressors, atropine for bradycardia
Hypersensitivity reaction to a sensitizing substance
ALLERGIC REACTION
anaphylactic shock
Epinephrine, antihistamines, H2-blockers (Zantac), Bronchodilators (albuterol), Steroids
given for anaphylactic shock
lab for septic shock
serum lactate level
patient with septic shock
HYPOTENSION (MASSIVE VASODILATION), TACHYCARDIA(HEART TRYING TO KEEP UP), TACHYPNEA, FEVER/HYPOTHERMIA
Physical obstruction that impedes the filling or outflow of blood from the heart.
Reduction in cardiac output.
obstructive shock
