With a manual resuscitator bag,the use of rapid rates causes which of the following?
1)An increase in fractional delivered oxygen concentration (FDO₂)
2)A decrease in FDO₂
3)An increase in tidal volume delivered
4)A decrease in tidal volume delivered
A) 1 and 4
B) 2 and 4
C) 1 and 3
D) 2 and 3

Question

Quizplus · Accepted Answer

Rapid rates with a manual resuscitator will decrease the amount of time the bag has to refill with the appropriate amount of volume and will also decrease the amount of oxygen accumulating in the reservoir thereby decreasing the delivered oxygen concentration and decreasing the tidal volume delivered.
