11. In pressure-regulated volume control, the peak inspiratory pressure is kept at a lowest level possible by
altering the _______ in response to changing airway or compliance characteristics.

A. peak flow and tidal volume
B. peak flow and inspiratory time
C. plateau pressure and tidal volume
D. plateau pressure and inspiratory time

12. Volume ventilation plus (VV1) provides the following options:

13. When the patient has no spontaneous breathing efforts, pressure-controlled ventilation delivers _______
-triggered breaths and a _______ is created and maintained for a preset inspiratory time.
A. pressure, PEEP
B. time, pressure plateau
C. flow, pressure plateau
