Spirometry: national guidelines for the testing and interpretation of results Interregional Public Organization “Russian Respiratory Society” All-Russian Public Organization “Russian Association of Specialists in Functional Diagnostics” All-Russian Public Organization “Russian Scientific Medical Soc

Spirometry is the most common method to assess respiratory function. It is widely used to obtain objective information for the diagnosis of respiratory diseases and monitoring the functional state of the respiratory system. In 2014, the Russian Respiratory Society approved the technical standards for performing spirometry. Improvements in measuring devices have necessitated updating technical standards and standardizing the result interpretation algorithm.Methods. This document on spirometry was prepared by a joint group of experts from the Russian Respiratory Society and the Russian Association of Specialists in Functional Diagnostics, who have experience in performing spirometry in accordance with quality criteria, analyzing the results of the study, and developing national standards.Results. The 2014 Spirometry Technical Standards were revised, including the addition of quality criteria for measurements and test quality assessment. Where necessary, evidence was provided to support the change. The experience and knowledge of the expert group members were used to develop these recommendations.Conclusion. Standards for spirometry and bronchodilator test and the result interpretation algorithm are presented to improve the measurement quality and consistency of data interpretation.
