A 45-year-old patient with congestive heart failure is receiving O2 through a 35 air-entrainment mask. With an O2 input of 6 L/min, what is the total output gas flow?
 
  a. 16 L/min
  b. 24 L/min
  c. 28 L/min

  2. Increase in the percent O2 delivered by the device

Answer to Question 1

ANS: D
Table 41-7 lists the approximate air-to-O2 ratios for several common O2 percentages.

Answer to Question 2

ANS: A
In the presence of flow resistance distal to the jet, the volume of air entrained always decreases. With less air being entrained, total flow output decreases, and the delivered O2 concentration in-creases.
