Answer to Question 1

ANS: B
When set properly, flow triggering has been shown to require less work of breathing than pres-sure triggering.

Answer to Question 2

ANS: C
A limit variable is the maximum value a variable can attain. It limits the variable during inspira-tion but does not end the inspiratory phase. The cycle setting ends inspiration. The trigger varia-ble begins inspiration, and there is no control over the minimum value.
