Asthma is a long-term condition in which sudden attacks make breathing difficult due to inflamed and narrowed airways. The causes of asthma can be attributed to genetics, allergies, and environmental exposures. People with a family history of asthma or allergic conditions are at higher risk. 

During an attack, muscles around the airways tighten up, causing inflammation and swelling, while excess mucus blocks airflow resulting in severe oxygen deprivation. During an attack, a rescue inhaler like Ventolin is needed to reduce the congestion quickly and restore normal breathing. A rescue inhaler may only help stop an asthma attack after it has begun – it is not a preventive against further asthma attacks.
