Answer to Question 1

ANS: B
Many adults with moderate or high ventilatory demands desire an inspiratory time between 0.6 and 0.9 sec.

Answer to Question 2

ANS: B
Across all modes of ventilation, inappropriately set sensitivity, inappropriate selection of PEEP, and the presence of auto-PEEP result in asynchrony. The one exception to this is NAVA, since NAVA is controlled by the diaphragmatic EMG signal; the presence of auto-PEEP does not af-fect the function of this mode.
