Answer to Question 1

ANS: A
He must always be combined with at least 20 O2. The higher the concentration of O2 used in a heliox mixture, the less likely it is that heliox would be beneficial. Heliox mixtures of less than 60 He are rarely used clinically.

Answer to Question 2

ANS: D
If the goal is to control gas delivery to a patient for O2 therapy or nebulized medication (see Chapters 36 and 38), a flowmeter must also be used.
