Real‐life application of respiratory oscillometry in pediatric asthma outpatient care: Feasibility and methodological aspects
Abstract
Asthma diagnosis can be challenging in children. Spirometry is highly effort-dependent and often normal in early disease. Forced oscillation technique (FOT) is an alternative to spirometry and is performed during tidal breathing. We investigated the feasibility of FOT with fewer acquisitions than suggested by technical standards in a pediatric outpatient care setting. We also studied the influence of tidal breathing patterns on FOT indices. Finally, the clinical utility of FOT was compared with spirometry. Ninety-five children aged 3-12 years performed FOT with single-frequency mode of 8 Hz (Resmon Pro, ResTech, Italy) during initial asthma assessment or follow-up. School-aged children (n = 61) also performed spirometry. In preschool age (
