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.[citation needed]In obstructive shock, CO is decreased, CVP is elevated, SVR is increased, and PAOP is increased which is similar to cardiogenic shock.[1] Obstructive shock can most easily be differentiated from cardiogenic shock by considering the greater clinical picture in the context of the PA catheter data (or echocardiography)[citation needed]
