There is no local predicted values for spirometry available in Bolivia. The aim of the present study is to establish moderne predicted values for healthy non-smokers recruited in a major city of Bolivia, Santa Cruz De La Sierra.
There is no local predicted values for spirometry available in Bolivia. To establish the predicted spirometric normal values in Bolivia, 500 healthy men and women, non-smokers will be recruited to perfom spirometry using following the actual ATS/ERS 2005 guidelines. The spirometer is a Bodybox 5500 (Medisoft, Belgium). The tests will be performed by a highly-trained pneumologist, Dr A. Ajata. Anthropometric variables recorded: age, sex, weight, standing and sitting height. Spirometric variables recorded: FEV1, FVC, PEF, FEV6, FEF25,50,75 and MEF Statistical anaysis will be done using R and SPSS softwares. Predicted equations will be compared with existing ones, especially the new GLI-2012 predicted equations.
