1

definition: shock

CV system cannot maintain adequate cellular perfusion

2

what is the most important indicator of overall prognosis for cardiogenic shock?

LV function

3

what is the primary cause of distributive shock?

sepsis

4

what is the classic situation for cardiogenic shock?

large amounts of contractile myocardium are lost or have severely depressed function resulting in reduced CO (decreased LVEF)

5

what are the etiologies of cardiogenic shock? which is primary?

acute MI (primary)
dilated cardiomyopathy
valvular
arrhythmia

6

what is the classic situation involving hypovolemic shock?

reduced circulating blood volume resulting in reduced cardiac filling and decreased CO

7

what are the two main etiologies of hypovolemic shock?

1. blood loss
2. fluid depletion

8

what is the effect of acidosis on heart function?

decrease

9

what are the general principles of therapy for shock?

cardiac rhythm monitoring
2 IVs fluid (NS)
ventilation
oxygen
arterial blood gasses
vasopressors
inotropics
