Abstract
Abstract: Background: To identify the anthropometric variables in equations/reference values of impulse oscillometry system (IOS) parameters in preschoolers, children and adolescents. Method: Systematic search on the databases MEDLINE/Ovid, SCOPUS and SciELO using the key words “preschool, child and adolescent”, “impulse oscillometry”, “reference values” and its variations. Results: This review considered a total of 13 articles. The studies presented height, weight, sex and age as the variables correlated to oscillometric parameters. Most studies do not present the correlation values of analyzed variables, and only a few presented the results considering gender differences. The coefficients of determination of the equations were low, specially for the samples including preschoolers. Height was identified as the most influent predictive variable to IOS parameters in the studied age group. Conclusion: Anthropometric variables, especially height, plays an important role determining reference values/equations for oscillometric parameters, however, the data acquisition method should be standardized.
