Summary
Spirometry is feasible in preschool children, offering a valuable tool for clinical practice and research. This study establishes reference values for lung function in European preschoolers.
Area of Science:
- Pediatric Pulmonology
- Respiratory Physiology
- Clinical Diagnostics
Background:
- Spirometric testing presents challenges in preschool-aged children.
- Establishing reliable lung function measurements in this age group is crucial.
Purpose of the Study:
- To assess the feasibility of dynamic spirometry in preschool children (3-6 years).
- To evaluate the utility of an animation program and European Respiratory Society guidelines for pediatric spirometry.
- To contribute reference values for European preschool children's lung function.
Main Methods:
- 652 children aged 3-6 years underwent dynamic spirometry with an animation program.
- European Respiratory Society guidelines were applied for test acceptability and reproducibility.
- Data from children achieving at least two acceptable forced expiratory maneuvers were analyzed.
Main Results:
- Spirometry was feasible in 92% of children, with 68% achieving at least three acceptable maneuvers.
- Lung function measurements (FEV1, FVC) showed increased acceptability and reproducibility with age.
- Standing height was a significant predictor of lung function, explaining 59% of FEV1 variance.
Conclusions:
- Dynamic spirometry is a feasible and useful method for assessing lung function in preschool children.
- The study provides valuable reference data for European preschool children, addressing a gap in current knowledge.
- Findings support the use of spirometry in pediatric clinical practice and research.
