Key Features Of A Nebulizer

1. Median Mass Aerodynamic Diameter (MMAD µm)

Nebulizers create aerosol droplets with a range of particle size diameters, and MMAD is the diameter that divides the mass of an aerosol in half . MMAD is one of the recommended parameter from European Respiratory Society for measuring nebulizer performance.

Upper Airways:

Chronic – Allergic Rhinitis (Hay Fever)

Infections – Rhinitis (Common Cold), Sinusitis, Laryngitis

Lower Airways

Chronic – Asthma, COPD

Infections – Bronchitis, Bronchiolitis, Pneumonia


2. Speed

Higher nebulization rate = Shorter treatment time

Nebulization rate is the amount of nebulized medication in ml coming out of the nebulizer per minute.

3. Aerosol Output

Amount of medication deposited in the lungs. It is measured using a breath simulator pump connected to a filter (chemical analysis of NaF in the filter)

It is a key parameter of Nebulizer efficiency.

4. Noise Level

Babies and children may be fearful of the noise generated by compressor type nebulizers therefore a mesh or ultrasonic nebulizer may be more ideal.

5. Portability

Recommended for cases where on the go treatment is needed.
