What are the 3 stages of shock? - 1. Compensatory
2. Progressive
3. Refractory/Irreversible
Compensatory stage of shock - Shock symptoms start to set in, but blood pressure is MAINTAINED
through the sympathetic nervous system response
Symptoms of compensatory shock - Tachycardia
Tachypnea

How is blood pressure maintained during the compensatory stage of shock? - The sympathetic
nervous system is stimulated, causing diffuse vasoconstriction and increasing heart rate/contractility.
This temporarily keeps blood pressure WDL.
Progressive stage of shock - Hypotension starts to set in as sympathetic stimulation and
compensatory mechanisms are not enough to maintain homeostasis.
Refractory stage of shock - Shock that is unresponsive to interventions as multisystem organ
failure starts to kick in
Symptoms of Refractory shock - Organ failure (Kidney failure r/t tubular necrosis, encephalopathy,
liver failure, etc...)
End-stage hypotension
