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