Answer to Question 1

ANS: D
A major advantage of ECMO is that ventilator support can be decreased once ECMO is initiated thus reducing the potential of ventilator induced lung injury. At times, the ventilator can even be discontinued reducing the potential of ventilator-associated pneumonia and allowing the patient a greater potential to more actively participate in activities of daily living. This is of particular importance in the pretransplant patient.

Answer to Question 2

ANS: B
During VV support cannulas are usually placed in the right internal jugular vein, right atrium, left or right femoral veins. In VA support, the venous cannulas are placed in the same locations as with VV support with the arterial cannula inserted into the aorta or either femoral artery.
