The value of functional research methods in the diagnosis of pre-asthma in children

Respiratory allergies are one of the most common and severe allergic pathologies in children. Our observations showed that bronchial asthma is formed in more than 80% of children through the stage of pre-asthma. However, its early diagnosis and adequate treatment in 90% of cases can prevent the transition to bronchial asthma. In this regard, the problem of studying the methods of early diagnosis of pre-asthma and ways to prevent its transformation into bronchial asthma is urgent and practically significant. Since the formation of pre-asthma and bronchial asthma is based on a violation of the function of external respiration, the purpose of our work was, firstly, to study the function of external respiration in case of pre-asthma, and secondly, to determine the diagnostic value of various methods for studying FVD in this pathology in children.
