An Asthmatic attack occurs when the air passages in the sufferers' lungs (bronchi) are narrowed as a result of contraction of the bronchial muscles, the swellings of the lining membrane, and the out pouring of mucus.

An Asthma attack is triggered by sensitivity to some substance, emotional stress, or vigorous exercise. Many Asthmatics are allergic to cold.

The symptoms of an asthma attack include difficulty in breathing out, tightness in the chest and weezing.
