Answer to Question 1

ANS: C
Respiratory rate is set by manipulation of the inspiratory and expiratory time control knobs. In-spiratory time is adjustable from 0.5 to 2 seconds. Expiratory time is adjustable from 0.6 to 6 seconds.

Answer to Question 2

ANS: B
In addition to flow triggering, there is a backup pressure-sensing trigger that pressure triggers a breath when the airway pressure drops below 3 cm H2O.
