Obstructive shock is a form of shock associated with physical obstruction of the great vessels or the heart itself. Pulmonary embolism and cardiac tamponade are considered forms of obstructive shock.
In obstructive shock, CO is decreased, CVP is elevated, SVR is increased, and PAOP is increased which is similar to cardiogenic shock. 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)
