Answer to Question 1

ANS: D
The FIO2 levels delivered by a nasal cannula vary with the flow rate setting. Generally, the FIO2 increases by about 4 for each liter of flow increase beginning with 1 L/min delivering approxi-mately 24 oxygen.

Answer to Question 2

ANS: D
High-flow devices are also called fixed-performance devices because they provide oxygen at flow rates high enough to completely satisfy a patient's inspiratory demands. These high-flow oxy-gen-delivery devices include air-entrainment masks (Venturi masks), incubators, oxygen tents, oxygen hoods, and high-volume aerosol devices.
