|
|
Aerosol |
Suspension of liquid or solid particles 0.001 - 100 micrometers in diameter in a carrier gas |
|
|
Aerosol therapy |
Delivery of aerosol particles to the lungs |
|
|

|
|
Chlorofluorocarbon |
Liquefied gas propellant used to administer medication from a metered dose |
|
|
Dead volume |
Amount of solution that remains in the reservoir of a small volume nebulizer once buttering begins causing a decrease in aerosolization |
|
|
Deposition |
Process of particles depositing out of suspension to remain in the lung |
|
|
Heterodisperse |
In reference to the size of particles in an aerosol meaning the particles are of different sizes |
|
|
Hydrofluoroalkane |
Non-toxic liquefied gas propellant you said Minister medication from an MDI |
|
|
In vitro |
Mechanically stimulating the clinical setting testing in a laboratory |
|
|

In reference to the size of particles in an aerosol meaning all particles are the same size |
|
|
Nebulizer |
Devices for making a fine spray or Mist also known as an aerosol generator |
|
|
Penetration |
Refers to the depth within the line reached by particles |
|
|
Poly disperse |
In reference to the size of particles in the aerosol meaning many different particle sizes |
|
|
Reservoir device |
Global term describing referring to extension auxiliary or add-on devices attached to mda's for administration this term can include spacer and valved holding chamber |
|
|
Spacer |
Simple to wear such a device with no one-way valves to contain the aerosol Cloud its purpose is simply to extend the MDI spray away from the mouth |
|
|
Stability |
Describing the tendency of aerosol particles to remain in suspension |
|
|
Valved holding chamber |
Space your device with the addition of a one-way valve to contain and hold the aerosol Cloud until inspiration occurs |
