  a. 0.75 second
  b. 1.16 second
  c. 1.65 second
  d. 2.4 seconds

Question 2

What is the flow rate necessary to deliver a tidal volume (VT) of 600 mL, with a constant wave-form, at a respiratory rate of 15 breaths/min with an I:E of 1:4?
 
  a. 36 L/min
  b. 40 L/min
  c. 45 L/min
  d. 60 L/min

Answer to Question 1

ANS: C
Total Cycle Time (TCT) = 60 sec/f; TCT  Inspiratory Time (TI) = Expiratory Time (TE)

Answer to Question 2

ANS: C
Total Cycle Time (TCT) = 60 sec/f; Inspiratory Time (TI) = TCT/Inspired (I) + Expired (E); Flow rate = Tidal Volume (VT)/Inspiratory Time (TI).
