In this scenario, the capacity with which the FOT allows for an evaluation of the respiratory system’s mechanical particularities from a non-invasive and with tidal volume perspective is of great clinical importance. Research demonstrates the capacity of this technique to be used in children aging less than 2 years, which can anticipate the diagnosis of respiratory diseases, allowing for the elaboration of adequate strategies sooner. The FOT presents an equivalent capacity of the spirometry to characterize the pulmonary function, be it in children with asthma or without it. In peripheral airway disorders the FOT presented higher analytical power, even though the variables obtained by the spirometry, such as the VEF 1 , presents grea- ter efficiency to demonstrate information about the diagnosis and control levels (4). CONCLUSIONS The FOT has a high sensitivity for evaluating the respiratory system, making it a promising tool for assessing pulmonary function in children with asthma. Part of its suc- cess is due to the simplicity of the method, being it non-inva- sive, easily applicable and for requiring almost no cooperation from the subject. In children with asthma this technique has shown greater accuracy for evaluation of smaller gauged pe- ripheral airways, serving as a complementary method to the spirometry and to enrich the diagnosis, allowing for a better understanding of the disease and its progression. Declaration of conflict of interest: there is no conflict to declare. BIBLIOGRAPHICS REFERENCES 1. Souza GAF de, Faria ÁCD, Lopes AJ, Jansen JM, Silva EC da, Melo PL de.
