Question

Quizplus · Accepted Answer

The optimal range for MMAD for delivering therapeutic aerosols to the central and lower airways is 2 to 5 µm. Particles in this size range have the ability to penetrate deeper into the lungs and reach the desired target area. Larger particles (>5 µm) tend to deposit in the upper airways, while smaller particles (<2 µm) may be exhaled before reaching the lower airways. Therefore, selecting an aerosol generator with an MMAD in the 2 to 5 µm range would help ensure maximum deposition in the central and lower airways.
