Answer to Question 1

ANS: C
In addition to the cylinder gas, a pressure-reducing valve with flowmeter is needed to deliver O2 at the prescribed flow. Standard clinical flowmeters deliver flows up to 15 L/min; flows used in alternative settings are typically in the 0.25 to 5.0 L/min range. For this reason, the respiratory therapist should select a calibrated low-flow flowmeter whenever possible. Alternatively, a preset flow restrictor can be used.

Answer to Question 2

ANS: A
The primary use of compressed O2 cylinders in alternative settings is for either ambulation (small cylinders) or as a backup to liquid or concentrator supply systems (H/K cylinders).
