How long can bronchospasm attacks last at a time?

Bronchospasm attacks can vary in duration, typically lasting from a few minutes to several hours. In some cases, they may persist longer if not treated effectively. The severity and length of an attack can depend on underlying conditions, such as Asthma or chronic obstructive pulmonary disease (COPD), and the individual's response to treatment. Prompt medical intervention can help shorten the duration of an attack.
