A physician requests that you switch from pressure-triggering a patient to flow-triggering. Which of the following new settings would be appropriate?
a. Base flow = 0 L/min; trigger at 2 L/min
b. Base flow = 10 L/min; trigger at ?2 cm H2O
c. Base flow = 10 L/min; trigger at 2 L/min
d. Base flow = 0 L/min; trigger at 10 cm H2O
ANS: C
For example, if you set the base continuous flow at 10 L/min and the trigger at 2 L/min, the ven-tilator will trigger when the output flow falls to 8 L/min or less.
