Warm Shock 
Cold Shock
  • THINK: sepsis, anaphylaxis, neuro/CNS
  • Warm, bounding & wide pulses, good cap refill, flushed
  • Due to  vasodilating effects of histamine and other anaphylatoxins
  • Tachycardia, Oliguria, Altered LoC
  • THINK: hypovolemic/cardiogenic/obstructive
  • Poor pulses, cold & clammy extremities, mottled skin, prolonged cap refill
  • vasoconstriction secondary to catecholamine surge
