Answer to Question 1

ANS: C
When the frequency is lowered, the piston is allowed more travel time. This results in greater piston displacement, or more delivered volume, the amount of which is unknown.

Answer to Question 2

ANS: C
With heliox use, the CareFusion AVEA's internal inspiratory flow sensor or the VarFlex flow sensor may be used.
