LISANTI, Raúl et al. Comparación de las pruebas de función pulmonar en población adulta sana de la Provincia de Mendoza, Argentina, con valores de referencia internacionales. Rev. am. med. respir. [online]. 2014, vol.14, n.1, pp.10-19. ISSN 1852-236X.

Pulmonary Function Tests (PFTs) are useful clinical tools, presenting regional, ethnic, and anthropometric differences. The aim was to perform PFTs among healthy adults in the Mendoza province, Argentina, so as to compare the values obtained in the aforesaid population with the international reference values, and determine if there is an adequate correlation. From November 2011 to June 2013, a prospective, transversal, observational and descriptive study was performed, with the participation of 103 healthy adults. The following PFTs were performed: spirometry, 6-minute walk test (6MWT), maximum static mouth pressures, and Peak Expiratory Flow. They were compared with the reference values, for spirometry with NHANES III and for T6m with Enright, using the lineal regression model; for Peak Expiratory Flow, since two measurement instruments were compared, the Bland-Altman method was also used. An adequate correlation was observed to exist between the values in Mendoza and the reference values proposed by NHANES III, particularly in the FEV1. As for FEV1/FVC, the use of the lower limit of normality was more appropriate in defining normality. The 6MWT showed that a shorter distance was covered by the tested population sample. The correlation observed for the maximum static mouth pressures between the population sample and the reference values was inadequate. An adequate correlation was observed between the automated and the portable Peak Expiratory Flow measurements. This is the first epidemiological study of normal PFT values in the Mendoza population, which contributes to the knowledge about our region.
