Answer to Question 1

ANS: C
For example, if you set the base continuous flow at 10 L/min and the trigger at 2 L/min, the ven-tilator will trigger when the output flow falls to 8 L/min or less.

Answer to Question 2

ANS: A
When compared with pressure, using flow as the trigger variable decreases a patient's work of breathing.
