Abstract
Asthma management in children aims to prevent ongoing symptoms, preserve lung function and support normal daily activities. Impulse oscillometry (IOS) represents a modern approach to evaluating lung function that is also suitable for performing in the pediatric asthma population. Further research is warranted to clarify the role of IOS in the early identification of small airway disease (SAD) as a potential treatable asthma trait and to understand its implications for personalized treatment strategies. Before the integration of IOS into routine clinical protocols, it is necessary to establish population-specific reference values. Further studies in the pediatric population are needed to evaluate the added value of IOS in combination with conventional spirometry and fractional exhaled nitric oxide (FeNO). Future pediatric asthma management guidelines may consider incorporating the assessment of SAD with IOS as a possible tool for its evaluation.
