A well-fitted nonrebreathing mask, adjusted so that the patient's inhalation does not deflate the bag (flows approximately 10 L/min), should provide inspired O2 concentrations in what range?
 
  a. 55 to 70
  b. 45 to 60
  c. 75 to 90
  d. 70 to 85

Answer to Question 1

ANS: A
As indicated in Table 41-3, however, modern disposable nonrebreathing masks normally do not provide much more than approximately 70 O2.

Answer to Question 2

ANS: C
At a flow less than 5 L/min, the mask volume acts as dead space and causes CO2 rebreathing.
