Spirometry and respiratory oscillometry: Feasibility and concordance in school children with asthma

This cross-sectional study evaluated the feasibility of respiratory oscillometry in 154 school children aged 6 to 14 years with asthma. The study also examined the concordance between oscillometry and spirometry outcomes, with spirometry (FEV1, FVC, FEV1/FVC ratio, FEF25–75) undertaken using the Vitalograph Pneumotrac device with Spirotrac software.
