Asthma is a disease that causes inflammation of the airways - especially the small airways. Measurement of lung function is therefore important for diagnosing asthma and for following the course of the disease during treatment. The traditional lung function methods such as spirometry measure predominantly the large and medium-sized airways and, to a lesser extent, the small airways, where there may be disease, particularly early in the disease course or in children with mild degree of disease.
The purpose of this project is to evaluate a new lung function method called multiple-breath washout, which examines the ability of the lungs to wash out a gas.
