  a. 3 L/min c. 8 L/min
  b. 5 L/min d. 11 L/min

Question 2

With a baseline pressure setting of 6 cm H2O and a sensitivity setting of 1.5 cm H2O, inspiration will begin at _____ cm H2O.
 
  a. 1.5 c. +1.5
  b. 4.5 d. +4.5

Answer to Question 1

ANS: B
The ventilator will begin inspiration when the expiratory flow is measured at 5 L/min (8 L/min  3 L/min = 5 L/min).

Answer to Question 2

ANS: D
The actual pressure at which the breath will be triggered is +4.5 cm H2O (6 cm H2O  1.5 cm H2O = 4.5 cm H2O).
