Shock

Hypovolemic

high HR, low JVP, cool skin. caused by blood/fluid loss. volume depletion.

Cardiogenic

high or low HR, high JVP, cool skin. caused by MI, valvular disease, trauma, cardiomyopathy. pump failure.

Distributive

high HR, low JVP, warm skin. caused by sepsis, anaphylaxis, neurogenic, adrenal failure. massive vasodilation.

Obstructive

high HR, high JVP, cool skin. caused by tamponade, massive PE (pulmonary embolism), tension pneumothorax. reduced filling

Compensated

tachycardia, tachypnea, pale cool clammy, B/P presents normal. body is trying to maintain perfusion; blood is shunted to vital organs.

Decompensated

altered mental status, thready pulse, mottled (marbled discoloration), cyanotic cold skin. body’s defense mechs fail; perfusion to vital organs drops drastically.

Arterial bleed

spurting bright red blood

Venous bleed

Early shock

tachycardia

Late shock

hypotension

Shock progression

narrow pulse pressure

Poor perfusion

weak/thready pulse

Inadequate perfusion

Delayed cap refill
