aerosol

 [ār´o-sol″]
a colloid system in which solid or liquid particles are suspended in a gas, especially a suspension of a drug or other substance to be dispensed in a cloud or mist. See also aerosol therapy.
aerosol clearance removal of particles that have been deposited in the respiratory tissues. Clearance may occur by ciliary transport, by phagocytosis, by encapsulation and immobilization in a deposit of fibrous tissue (in which case the particles remain in the body), and by dissolving in tissue fluid and subsequently diffusing into the general circulation where the particles are metabolized.
aerosol deposition the depositing of aerosol particles onto a nearby surface, especially deposition or retention of the particles within the respiratory system. Closely related to aerosol penetration and affected by the same factors.
aerosol penetration the maximum distance aerosol particles can be carried into the respiratory tract by inhaled air. Depth of penetration increases as particle size decreases. Factors affecting where aerosol particles will be deposited and how deeply they can penetrate are: gravity, kinetic activity of gas molecules, inertial impaction, physical nature of the particle, and the ventilatory pattern.
aerosol therapy use of an aerosol for respiratory care in the treatment of bronchopulmonary disease. The major purpose of this is the delivery of medications or humidity or both to the mucosa of the respiratory tract and pulmonary alveoli. Agents delivered by aerosol therapy may act in a number of ways: (1) to relieve spasm of the bronchial muscles and reduce edema of the mucous membranes, (2) to render bronchial secretions more liquid so that they are more easily removed, (3) to humidify the respiratory tract, and (4) to administer antibiotics locally by depositing them in the respiratory tract.

Physical and chemical substances used as medical aerosols include drugs that act as bronchodilators and decongestants, such as epinephrine, ephedrine, isoproterenol, atropine, and the steroids. Wetting agents administered as aerosols to render the bronchial secretions more liquid include tyloxapol and acetylcysteine. The choice of antibiotics to be given as aerosol therapy is determined by the patient's specific condition and the preference of the health care provider. Most standard antibiotic drugs are available in aerosol form.

In general, the respiratory therapist is concerned with factors that affect how deeply aerosol particles can penetrate into the bronchial tract and the locations at which these particles are deposited on the bronchial mucosa and alveolar tissues. Depth of penetration is affected by particle size. Particles as large as 100 μm and as small as 5 μm are trapped in the nose. Those 2 to 5 μm in size are deposited somewhere in the respiratory tract proximal to the alveoli. Deposition in the alveoli is 90 to 100 per cent for particles 1 to 2 μm in size.

Because aerosol particles are so small, they present the phenomenon of brownian movement as they are bombarded by the molecules of the gas in which they are carried. The velocity with which these particles move about directly affects their diffusion and deposition onto nearby surfaces. Thus the type of aerosol generator used in aerosol therapy is of primary importance.

Another factor affecting penetration and deposition of aerosol particles that should be of concern to respiratory therapists and other members of the health team who are teaching patients the techniques of effective aerosol therapy is that of ventilatory pattern. The ideal pattern of breathing for optimum delivery of aerosol particles is that of slow, moderate deep breathing with breath holding at the end of each inhalation.
