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

Question 2

Compared to using pressure as the trigger variable, what is the major advantage of flow-triggering?
 
  a. Decreased work of breathing
  b. Improved minute ventilation (VE)
  c. Decreased physiologic dead space
  d. Improved arterial oxygenation

Answer to Question 1

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.

Answer to Question 2

ANS: A
When compared with pressure, using flow as the trigger variable decreases a patient's work of breathing.
