Which of the following flow-termination settings for a pressure-supported breath that has a peak inspiratory flow of 30 L/min would allow enough time for a visible plateau on the pressure-time curve?
A) 5 L/min
B) 20 L/min
C) 20% of peak flow
D) 30% of peak flow

The longest inspiratory time provides a visible plateau on the pressure-time scalar.This is caused by a flow termination that takes the longest time to reach.The flow termination that is lowest provides the most visible plateau on a pressure-time scalar.Because 20% of the peak flow of 30 L/min is 6 L/min and 30% of 30 L/min is 9 L/min,the lowest flow in this case is 5 L/min.
