Status Asthmaticus is a chronic respiratory disorder in which a person experiences difficulty in breathing, accompanied by wheezing and a “tight” chest. Additional symptoms can be a dry cough and vomiting (usually in children).

An asthma attack may start suddenly. The fear and worry that this causes can prolong the attack.

Attacks are caused by a narrowing of the small bronchial tubes in the lungs.

The most common kind of asthma (allergic bronchial asthma) is caused by an allergic reaction.

Many pollens, molds, dust (especially dust containing the house mite), and animal hair and dander can cause allergic-type asthma attacks.

Asthma is thought to be caused by a combination of genetic and environmental factors. Its diagnosis is usually based on the pattern of symptoms, response to therapy over time and spirometry.

It is clinically classified according to the frequency of symptoms, forced expiratory volume in one second (FEV1), and peak expiratory flow rate.

Treatment of acute symptoms is usually with a short-acting broncodilator and oral corticosteroids.

In very severe cases, intravenous corticosteroids, magnesium sulfate, and hospitalization may be required.

Symptoms can be prevented by avoiding triggers, such as allergens and irritants, and by the use of inhaled corticosteroids.
