8. WHAT IS NEBULIZING THERAPY
What is a nebulizer?
The name of the device comes from the Latin word nebula that means fog, cloud. The nebu-
lizer system is a device that turns a liquid drug into a fine aerosol under the influence of
the compressed air. Aerosol is a drug suspension. So, nebulizing therapy is an inhalation
therapy with the help of aerosols.
Inhalation therapy has been used for treatment of lung diseases for a long time. The ancient
civilizations of Egypt, India, Chine, the Middle East, Greece are know to have used inhala-
tions of evaporations from menthol, eucalyptus, different plants.
For patients with lung diseases nebulizing therapy seems to be the most rational one since
big drug doses come very fast to the respiratory tract directly.
How does the nebulizer system work?
Nebulizer directs an aerosol containing larger and smaller particles to the respiratory tract.
The gravity makes the larger particles accumulate on the walls of the upper respiratory pas-
sages while the smaller particles have enough time to reach the lower bronchial branches.
Therefore the drug comes to all parts of the patient’s bronhial tree, including the smallest
bronchi and alveole, and gets into the blood vessels on the walls of the alveole in big thera-
peutic dozes with tiny or none side effects. Some drugs are very slow to be absorbed from
