Estudo piloto de valores de referência de Pletismografia para crianças de 06 a 12 anos de idade

Abstract

Introduction: The pulmonary function tests are important tools in the diagnosis and management of respiratory diseases in adults and children. The body plethysmography is a fast and accurate method to measure lung volumes and airway resistance. Recent publications have reference values for children plethysmography in populations of different races and different ages. Emerging, so the interest in generating values of healthy children to the local population. Aim: To evaluate the feasibility of generating reference values for the variables of plethysmography in children aged 06 years to 12 years of age. Methods: A survey was conducted between march and december 2011, where 32 healthy children aged between 06 and 12 years were selected from two elementary schools of Porto Alegre RS. Absolute lung volumes were measured FRC, RV and TLC as well as airway resistance (sRAW). Success was defined when the child produced at least two acceptable and reproducible curves. Results: 19 children had their tests validated. After comparing the parameters obtained with the reference and predicted values with results found by chilean study, the observed trend values of different lung volumes of both studies already published. Conclusion: The values of lung volumes found are smaller than the reference values used in comparison. These differences may be related to anthropometric characteristics of populations due to different aspects of ethnicity.
