Espirometría forzada en niños escolares sanos de 9 años de edad bajo las recomendaciones de la ATS/ERS Cuenca 2013

Abstract

Introduction: The evaluation of lung function should be with forced spirometry, reference values for spirometric indices must be obtained in each region by its own characteristics, in order to make a proper diagnosis and management of respiratory disease. Objective: To determine reference values for forced spirometry in healthy children 9 years under the recommendations of the ATS / ERS of the urban area of the city of Cuenca, 2013. Materials and Methods: Descriptive study in 173 children of both sexes, healthy 9 years old, studying in urban schools of the city of Cuenca. The sample was obtained between the months of March to June 2013 through forced spirometry and spirometry values were analyzed using multivariate linear regression. Results: Of the 173 spirometry, 98 children (56.6%) and 75 girls (43.4 %) were included. Spirometric values for FVC indices were an average of 2.06 liters and a DS of 0.38, for a mean FEV1 1.94 liters and a DS of 0.34, relative to the average CVF/VEF1 94.15% and a DS of 4.91, an average of 3.74 for FEF25 and a DS of 0.82 for FEF50 an average of 2.95 and a DS of 0.67 and for FEF75 one average of 1.62 and a DS of 0.50. Conclusions: The spirometric values should be obtained in each population and age group for better assessment of pulmonary function. The size is correlated with most of spirometric indices (FVC, FEV1, FEF25, FEF50), whereas the weight influences the FVC, FEV1 and FEF75 and sex influences only in FEF25.
