Nomogramas de ecuaciones de referencia espirométrica SER 2009

Abstract

Spirometric nomograms for Chilean normal adults As a result of the availability of programmes to detect and treat respiratory disease in Chile there has been a greater use of spirometry in diagnosis. To be able to correctly interpret spirometry results there must be reference patterns which, ideally come from the same population in which they will be used. In order to facilitate the use and application of new spirometric reference equations recently calculated for the adult population, there follows a series of nomograms. These nomograms have been designed for each of the following parameters: gender, age, and size of subjects between 19 and 50 years old and also for subjects over 51 years old. These equations are taken from 5 national studies. These studies included a population which complied with universal criteria to determine reference va-lues (1.174 subjects, between 19 and 94 years old), spirometries were carried out on this population following international recommendations (ATS).
