          Abstract

          RESUMEN Introducción: La espirometría, también conocida como prueba funcional ventilatoria, es una de las pruebas no invasivas que con más frecuencia se realiza en todo el mundo, para el estudio del aparato respiratorio, es de gran utilidad clínica, permite establecer la existencia de alteraciones funcionales incipientes del sistema respiratorio. Objetivo: Realizar una actualización del estado del conocimiento acerca de la importancia de contar con valores de referencia, en cada país, para el estudio de la función pulmonar. Métodos: Se realizó una revisión, con información actualizada del comportamiento de los valores de referencia de las pruebas funcionales ventilatorias en el mundo y en Cuba. Conclusión: Se concluye enfatizando en la necesidad de aplicar ecuaciones de predicción y valores de referencia de la función ventilatoria a partir de la propia población que se estudie, con lo que se obtienen resultados más cercanos a lo real. Además, lograr contar con tablas de normalidad cubanas de la función pulmonar para un mejor diagnóstico y conducta posterior.

          ABSTRACT Introduction: Spirometry, also known as a ventilatory functional test, is one of the non-invasive tests that is most frequently performed worldwide, for the study of the respiratory system, it is of great clinical utility, it allows establishing the existence of functional alterations incipients of the respiratory system. Objective: To update the state of knowledge about the importance of having reference values, in each country, for the study of lung function. Methods: A review was carried out, with updated information on the behavior of the reference values of the ventilatory functional tests in the world and in Cuba. Conclusion: It is concluded by emphasizing the need to apply prediction equations and reference values of the ventilatory function from the population under study, which results closer to the real. In addition, to have Cuban normality tables of lung function for a better diagnosis and subsequent behavior.

          Multi-ethnic reference values for spirometry for the 3-95-yr age range: the global lung function 2012 equations.

          The aim of the Task Force was to derive continuous prediction equations and their lower limits of normal for spirometric indices, which are applicable globally. Over 160,000 data points from 72 centres in 33 countries were shared with the European Respiratory Society Global Lung Function Initiative. Eliminating data that could not be used (mostly missing ethnic group, some outliers) left 97,759 records of healthy nonsmokers (55.3% females) aged 2.5-95 yrs. Lung function data were collated and prediction equations derived using the LMS method, which allows simultaneous modelling of the mean (mu), the coefficient of variation (sigma) and skewness (lambda) of a distribution family. After discarding 23,572 records, mostly because they could not be combined with other ethnic or geographic groups, reference equations were derived for healthy individuals aged 3-95 yrs for Caucasians (n=57,395), African-Americans (n=3,545), and North (n=4,992) and South East Asians (n=8,255). Forced expiratory value in 1 s (FEV(1)) and forced vital capacity (FVC) between ethnic groups differed proportionally from that in Caucasians, such that FEV(1)/FVC remained virtually independent of ethnic group. For individuals not represented by these four groups, or of mixed ethnic origins, a composite equation taken as the average of the above equations is provided to facilitate interpretation until a more appropriate solution is developed. Spirometric prediction equations for the 3-95-age range are now available that include appropriate age-dependent lower limits of normal. They can be applied globally to different ethnic groups. Additional data from the Indian subcontinent and Arabic, Polynesian and Latin American countries, as well as Africa will further improve these equations in the future.

            Reference spirometric values using techniques and equipment that meet ATS recommendations.

            Forced expiratory volumes and flows were measured in 251 healthy nonsmoking men and women using techniques and equipment that meet American Thoracic Society (ATS) recommendations. Linear regression equations using height and age alone predict spirometric parameters as well as more complex equations using additional variables. Single values for 95% confidence intervals are acceptable and should replace the commonly used method of subtracting 20% to determine the lower limit of normal for a predicted value. Our study produced predicted values for forced vital capacity and forced expiratory volume in one second that were almost identical to those predicted by Morris and associates (1) when the data from their study were modified to be compatible with the back extrapolation technique recommended by the ATS. The study of Morris and colleagues was performed at sea level in rural subjects, whereas ours was performed at an altitude of 1,400 m in urban subjects. Either the present study or the study of Morris and co-workers, modified to back extrapolation, could be recommended for predicting normal values.
