Answer to Question 1

ANS: C
When the maximum safety pressure is reached, the ventilator will sound an alarm, limit the pres-sure, and cycle out of inspiration, ending inspiration early.

Answer to Question 2

ANS: C
The pressure waveform shown in column C has the characteristic flat top of a pressure limit. Be-cause the breath does not end when the pressure limit is met, the breath is time cycled.
