Asthma has become more widespread in recent decades. As the most common chronic illness in children, childhood asthma causes more missed school and places more limits on activity than any other disease. Childhood asthma and adult asthma have the same underlying cause — continuous inflammation of the airways leading to the lungs. This inflammation makes the airways overly sensitive and prone to tightening and constricting when irritated. Fortunately, childhood asthma is treatable. With the right medications and action plan, a child with asthma can enjoy normal activities with few disruptions. The aims and objectives of this study were to establish a data base of children presenting with reversible airway narrowing and to see their response to pulse therapy and are followed for three months.
