  a. 19 mL c. 53 mL
  b. 22 mL d. 88 mL

Question 2

The stable jet flow from the ARABELLA System causes which of the following?
 
  a. A decrease in the patient's work of breathing
  b. A higher continuous positive airway pres-sure level for less flow through the system

Answer to Question 1

ANS: C
Tidal volume (liters) = Inspiratory time (seconds)  Flow (L/min)  60 = 0.4  8  60 = 0.053 L, or 53 mL.

Answer to Question 2

ANS: D
A more stable jet flow seems to require a more substantial patient expiratory flow to cause the device to switch into expiration. The additional flow that is required for the ARABELLA sug-gests that a patient must work harder to breathe when this system is used.
