Answer to Question 1

ANS: A
Automatic tube compensation is similar to the flow assist of proportional assist ventilation but only considers the resistance of the endotracheal tube.

Answer to Question 2

ANS: B
More specifically, the decrease in left ventricular output corresponded to the increase in pleural pressure that occurred with PPV.
