Manifestations of shock vary based on

stage

5

Manifestations of shock often include:

- hypotension
- tachycardia

Shock: end result leads to hypoxia of end-organ tissues, especiall these

- kidneys
- brain
- heart

8

What are the 3 classes of shock?

- cardiogenic
- hypovolemic
- reduced system vascular resistance

9

Cardiogenic shock occurs due to

decreased cardiac output

10

Etiologic factors of cardiogenic shock

- arrhythmias
- acute MI
- severe CHF
- septic
- neurogenic
- cardiac tumor
