| Frage | Antworten |
| Stability | Tendency of an aerosol to remain in suspension. |
| Aerosol | Suspension of liquid or solid particles in a gas. |
| Spacer | Reservoir device used with aerosol delivery devices such as MDI's to optimize aerosol drug delivery. |
| Aerosol therapy | delivery of aerosol particles into the respiratory system for therapeutic purposes. |
| Chlorofluorocarbons (CFC's) | Older propellant for MDI's that damage the ozone layer and are reactive in some patients so they are currently banned. |
| Deposition | Aerosol particles falling out or "raining out" of suspension. |
| Penetration | How deep the aerosol particles travel into the respiratory system. |
| Small Volume Nebulizer (SVN's) | A medicated aerosol delivery device that uses a gas powered source to form and deliver the aerosol continuously over a period of usually 8-12 minutes. |
| Ultrasonic Nebulizer | Aerosol delivery device that provides increased speed and capacity while minimizing noise. |
| Micron | One- millionth of a meter, the order of magnitude of how small these aerosol particles are. |
| Metered dose Inhaler (MDI's) | A medicated aerosol delivery device that delivers measured doses (metered puffs) of aerosol from a small gas powered canister. |
| Medicated aerosol | Medicine that has been made into an aerosol to be delivered into the respiratory system. |
| Inertial Impaction | The impacting of aerosol particles on airway walls because of inertial energy. |
| Hydrofluoroalkanes (HFA's) | Replacing CFC's as metered dose inhalant (MDI) propellants, because they do not damage the ozone layer and are not as reactive in patients. |
| Dry powder inhaler (DPI's) | Medicated aerosol delivery device that delivers a powdered (solid) aerosol to the respiratory system. |
| Mucolytics | Breaks down secretions to clear the lungs. Sometimes instilled directly into the lungs in liquid form via the endo-tracheal tube or bronchoscope. Common drug: acetylcysteine (mucomyst) |
| Antimicrobials | Aerosolized antibiotics and antiviral agents to fight both bacterial and viral infections. Common drugs: gentamicin, amphotericin B, ribavirin, pentamidine. |
| Nasal Decongestants | Nasal spray, OTC metered spray, produce larger particles, powerful vasoconstrictors, can increase blood pressure. Common Drugs: neo-synephrine, oxymetazoline. |
| Corticosteroids | Control asthma and prevent or decrease severity of attack, backbone med used to treat persistent asthma. Controls airway inflammation for improved lung function and a decreased need for short acting bronchodilators. Common Drugs: qvar, vanceril, flovent, azmacort. |
| Mast cell stabilizers | Desensitizes the allergic response for asthma attacks. Common Drugs: cromolyn sodium and nedocromil sodium. |
| Bronchodilators | Enlarge the diameter of the airway and relaxes the smooth muscle. Common Drugs: albuterol (proventil), ipratropium (atrovent), pirbuterol (maxair), salmeterol (serevent). |
