Answer to Question 1

ANS: D
VC-CMV with PEEP causes the highest mean airway pressure; this results in the greatest reduc-tion in venous return and thus cardiac output.

Answer to Question 2

ANS: B
High tidal volumes and/or high levels of PEEP result in increased resistance to blood flow through the pulmonary circulation; this increases right ventricular afterload. In addition, the right ventricle becomes overdistended, causing a decrease in RV output. Dilation of the RV can also force the interventricular septum to move to the left. Left ventricular output may also be de-creased because of the expanding lungs. This plus the decreased venous return lowers cardiac output and decreases the amount of blood perfusing the myocardium.
