Bronchospasm

Bronchospasm is the sudden constriction of the smooth muscles in the bronchi, leading to narrowing of the airways and difficulty in breathing. This condition is clinically significant as it can exacerbate respiratory diseases such as asthma and chronic obstructive pulmonary disease (COPD), resulting in acute respiratory distress. A key association is the role of allergens or irritants in triggering bronchospasm, which can lead to severe complications if not promptly managed.
