An asthma attack is exactly that - the muscles around the airways and the lining of the air passages tighten. Swelling reduces the amount of air that can pass through the airways and leads to a high-pitched, wheezing sound. Asthma attacks can become life-threatening if the airflow in the lungs becomes severely blocked.
