What is bronchoconstriction?

Bronchoconstriction refers to the narrowing of the airways, primarily due to the contraction of the smooth muscles surrounding the bronchial passages. This physiological response can occur in reaction to various stimuli, such as allergens, irritants, or other factors that impact the bronchial tissues. When the muscles tighten, airflow becomes restricted, leading to difficulty in breathing, which is particularly evident in conditions like asthma. Understanding bronchoconstriction is vital for EMTs since the recognition of this condition can prompt urgent interventions to relieve airway obstruction and improve patient breathing.
