Delivers fine mist
Does not use propellants
Extremely small particle size
Decreased drug deposited in mouth/oropharynx
Respimates
Dry micronized powder
Breath activated
Deliver more drug to lungs vs. MDI
Dry-Powder Inhalers (DPI)
Makes drug solution into a mist
Most seen with pediatrics

Does not require coordinated inhalation from patient
Variety of attachments including masks for less cooperative patients
Can administer oxygen and nebulizer medication simultaneously for hypoxic pateints
Some meds are only Neb solutions
What are the disadvantages of a Nebulizer?
Potentially increased risk of aerosolization of pathogens
Longer dose delivery time
Some units require an outside power source
Some units require coppered oxygen air
