Summary
Spirometry using incentive games is feasible in preschool children with asthma, enabling reliable respiratory function assessment. Refined quality criteria ensure accurate results in this age group.
Area of Science:
- Pediatric Pulmonology
- Respiratory Medicine
- Asthma Research
Background:
- Assessing respiratory function in preschool children (PSC) with asthma is challenging.
- Previous quality-control criteria for spirometry in children had limitations.
- A larger dataset is needed to refine spirometry acceptability and repeatability criteria for PSC.
Purpose of the Study:
- To refine spirometry quality-control criteria for 2-5-year-old preschool children with asthma.
- To evaluate the feasibility of obtaining acceptable spirometry maneuvers in this population.
- To establish optimal thresholds for spirometry acceptability and repeatability in young children with asthma.
Main Methods:
- Spirometry with incentive games was performed on 207 preschool children with asthma.
- Data from 178 children (86%) with at least two acceptable maneuvers were analyzed.
- Quality-control criteria (Vbe, Vbe/FVC, time-to-PEF, DeltaFVC, DeltaFEV(1), DeltaFEV(0.5)) were evaluated and refined.
Main Results:
- Optimal thresholds for spirometry acceptability and repeatability were determined.
- Specific criteria were defined: Vbe ≤75 ml and ≤10% FVC, time-to-PEF <120 msec, DeltaFEV(1) & DeltaFEV(0.5) ≤110 ml and ≤10%, DeltaFVC ≤100 ml and ≤12.5%.
- These criteria were met by a high percentage of children (85-94%), suggesting feasibility.
Conclusions:
- A majority of preschool children with asthma can perform acceptable spirometry maneuvers.
- The refined acceptability and repeatability criteria are applicable to preschool children.
- Spirometry, with appropriate quality control, can be a valuable tool for assessing respiratory function in preschool children with asthma.
