2) Continuous nebulizer with collection reservoir bag
3) Breath-enhanced nebulizer
4) Breath-actuated nebulizer

Question 2

Deposition

Answer 2

> 5um-Inertial Impaction (Oropharynx / Hypopharynx)
~ Suspended particles in motion collide and are deposited on a surface
1-5um-Sedimentation (Central Airways)
~ Deposited owing to gravity
1-3 (Parenchyma: Alveolar region)
<3um-Brownian Diffusion (Respiratory Region)
~ Particles <.5 have greater retention rate in lungs
