Asthma is an inflammation and obstruction of the bronchial tubes - the passages that allow air to enter and leave the lungs. During an asthma attack, the muscles that surround the bronchial tubes constrict, narrowing the air passages and making it extremely difficult to breathe. There is often a feeling of tightness and a wheezy or rattling sound in the chest.
Asthma attack signs and symptoms include:Severe shortness of breath, chest tightness or pain, and coughing or wheezing, Low peak expiratory flow (PEF) readings, if you use a peak flow meter, Worsening symptoms despite use of a quick-relief (rescue) inhaler. Some people with asthma may go for extended periods without having an asthma attack or other symptoms, interrupted by periodic worsening of their symptoms.

If your symptoms don't improve, seek immediate medical care.Home treatment steps to stop an asthma attack generally include taking 2.5 to 5 milligrams of albuterol every 20 minutes for an hour.
