Increase airflow by dilating constricted airways through relaxation of the smooth muscles
that surround the bronchioles and bronchi
Bronchodilators are used to treat asthma, emphysema, chronic obstructive pulmonary disease
(COPD), and exercise-induced bronchospasm. Most bronchodilators provide metered dosages
of the medication and may employ a spacer as a reservoir for the medication. (See Fig. 4–13.)
Decrease inflammation in the airways, reducing swelling and mucus production and mak-
ing breathing easier
Corticosteroids are used to treat chronic lung conditions, such as COPD and asthma.
Produce a fine spray (nebulizer) to deliver a medication directly into the lungs (See
Fig. 4–14.)
