Answer to Question 1

ANS: C
The maximum pressure limit is a safety mechanism used during volume ventilation to avoid ex-cessive pressure in the lungs. When the pressure measured by the ventilator reaches the maximum pressure limit inspiration ends. This means that the inspiratory time will be decreased and the volume delivered will be less than the set volume. Therefore, reaching maximum pressure limit causes the delivered breath to be pressure cycled.

Answer to Question 2

ANS: B
Cycle is the term used to call the variable that is used to end inspiration. Limit is the maximum setting for a variable. Trigger is the term used to call the variable that is used to begin inspiration. Baseline is the pressure at the end of inspiration.
