Aerosol
|
A suspension of solid or liquid particles within a gas.
|
|
Aerosol Therapy
|
Delivers either solid or liquid aerosol particles into the respiratory tract for therapeutic purposes.
|
|
Chlorofluorocarbons
|
Older propellant for MDI's; damage the ozone layer and are reactive in some patients so they are currently banned.
|
|
Deposition
|
aerosoled particles falling out of suspension.
|
|
Dry-powder inhaler
|
Medicated aerosol delivery device that delivers a powdered (solid) aerosol to the respiratory system.
|
|
Hydrofluoroalkanes
|
replacing chlorofluorocarbons as merered-dose inhalant propellants, because they do not damage the ozone layer and are not as reactive in patients
|
|
Inertial Impaction
|
the impacting of aerosol particles on airway walls because of inertial energy.
|
|
Medicated Aerosol
|
medicine that has been made into an aersol to be delivered into the respiratory system.
|
|
Metered-dose inhaler
|
a medicated aerosol delivery device that delivers measured doses (metered puffs) of aerosol from a small gas-owdered canister.
|
|
Micron
|
one-millionth of a meter.
|
|
Penetration
|
how deep the aerosol particles travel into the respiratory system.
|
|
small-volume nebulizer
|
a medicated aerosol delivery device that uses a gas-powdered source to form and deliver the aerosol continuously over a period of usually 8-12 minutes.
|
|
spacer
|
reservoir device used with aerosol delivery devices such as MDI's to optimize aerosol drug delivery.
|
|
stability
|
tendency of an aerosol to remain in suspension.
|
|
ultrasonic nebulizer
|
aerosol delivery device that provides increased speed and capacity while minimizing noise.
