Which type of disorder is bronchospasm classified as?

Bronchospasm is classified as an obstruction disorder because it involves the narrowing of the airways due to muscle contraction around the bronchioles, which impairs airflow. This condition can lead to difficulty breathing and is commonly associated with asthma and other respiratory conditions.

In obstructive disorders, the primary issue is the blockage or narrowing of the airways, leading to reduced airflow during expiration. This is different from restrictive disorders, where the lung volume is reduced (e.g., due to stiffness in the lungs or chest wall). Infectious disorders involve pathogens causing illness (e.g., pneumonia), while chronic disorders are those that persist over time. Bronchospasm specifically relates to the obstruction of airflow due to airway constriction, making it clear why it fits into the category of obstruction disorder.
