Obstructive shock

From Wikipedia, the free encyclopedia

Obstructive shock is a form of shock associated with physical obstruction of the great vessels or the heart itself.[1] Pulmonary embolism and cardiac tamponade are considered forms of obstructive shock.[2]

Obstructive shock has much in common with cardiogenic shock, and the two are frequently grouped together.[3]

Some sources do not recognize obstructive shock as a distinct category, and categorize pulmonary embolism and cardiac tamponade under cardiogenic shock.
