Answer to Question 1

B
The minimal leak technique consists of injecting air into the cuff until no leak is heard and then withdrawing the air until a small leak is heard on inspiration. Problems with this technique include difficulty maintaining positive end-expiratory pressure and aspiration around the cuff.

Answer to Question 2

D
Contractility of the left side of the heart is measured by the left ventricular stroke work index.
