What is a common symptom of asthma during an attack?

During an asthma attack, a common symptom is difficulty in breathing, particularly when exhaling. This occurs because the airways become inflamed and constricted, leading to a narrowing of the bronchial tubes. Consequently, the airflow is limited, which results in the characteristic wheezing and a feeling of tightness in the chest. Individuals often struggle to pass air out of their lungs, which can create a sensation of breathlessness.

While rapid heart rate, excessive sweating, and chest pain can sometimes accompany an asthma attack or occur in related respiratory distress, they are not hallmark signs of the attack itself. The primary issue in asthma is the obstruction of airflow, making breathing out significantly more challenging. Understanding this key symptom helps in recognizing and responding effectively to an asthma attack during first aid scenarios.
