Which of the following ventilator adjustments would decrease inspiratory time?
1) Increase the peak flow.
2) Increase the tidal volume.
3) Change the flow pattern from a decelerating wave to a square wave.
A)1 and 3 only
B)1 only
C)2 and 3 only
D)1, 2, and 3

1) Increasing the peak flow would decrease inspiratory time because it would deliver the set tidal volume more quickly.
2) Increasing the tidal volume would increase inspiratory time if the flow rate remains constant, but it is not a specific option for decreasing inspiratory time.
3) Changing the flow pattern from a decelerating wave to a square wave would decrease inspiratory time because all of the tidal volume would be delivered at the set peak flow rate without deceleration.
