Reversibility of lung function in pre-school children with asthma or asthma-like symptoms

摘要

Background.Diagnosing asthma in pre-school children with asthma-like symptoms is a major problem. From a clinical viewpoint, because of the specificity and variability of symptoms, it is currently almost impossible to distinguish the asthmatic from the non-asthmatic child. Since asthma is defined as a reversible airway obstruction reversibility testing could be of additional value.
