The respiratory therapist needs to deliver a bland aerosol to a 24-month-old child through a spin-ning disk device. The appropriate flow setting is ___ L/min to ___ L/min
a. 3; 5 c. 10; 15
b. 6; 8 d. 20; 22
ANS: D
Larger versions of these devices (with 2- to 3-L reservoirs) are used to deliver bland aerosols into mist tents. These enclosure systems can generate flow rates greater than 20 L/min, with water outputs as high as 5 mL/min (300 mL/hr). Because heat buildup in enclosures is a problem, these systems are always unheated.
