[Airflow limitation in Brazilian Caucasians: FEV1/FEV6 vs. FEV1/FVC].
OBJECTIVE To evaluate the use of the forced expiratory volume in one second/forced expiratory volume in six seconds (FEV1/FEV6) ratio as an alternative to the FEV1/forced vital capacity (FVC) ratio in the detection of mild airway obstruction. METHODS Reference equations for the Brazilian population in 2006 were used in order to determine the lower limits of normality for the FEV1/FEV6 and FEV...
متن کاملPredicting reduced TLC in patients with low FVC and a normal or elevated FEV1/FVC ratio.
OBJECTIVE To use clinical and spirometry findings in order to distinguish between the restrictive and nonspecific patterns of pulmonary function test results in patients with low FVC and a normal or elevated FEV1/FVC ratio. METHODS We analyzed the pulmonary function test results of 211 adult patients submitted to spirometry and lung volume measurements. We used the clinical diagnosis at the t...
متن کاملReliability of FEV1/FEV6 to Diagnose Airflow Obstruction Compared with FEV1/FVC: The PLATINO Longitudinal Study
QUESTION A 6-second spirometry test is easier than full exhalations. We compared the reliability of the ratio of the Forced expiratory volume in 1 second/Forced expiratory volume in 6 seconds (FEV1/FEV6) to the ratio of the FEV1/Forced vital capacity (FEV1/FVC) for the detection of airway obstruction. METHODS The PLATINO population-based survey in individuals aged 40 years and over designed t...
متن کاملA mathematical reason for FEV1/FVC dependence on age
BACKGROUND Recent studies have showed that FEV1/FVC describing correspondence between the forced expiratory volume in one second (FEV1) and forced vital capacity (FVC) depends significantly on age. However, the nature of this dependence is uncertain. The study aim is to analyze mathematically the relationship between FEV1 and FVC to find a cause of the FEV1/FVC dependence on age in healthy subj...

Abstract Background: Workers who exposed to cotton dust are at risk of some occupational lung diseases such as byssinosis and chronic bronchitis. In general respiratory symptoms like chronic cough, sputum and dyspnea are more common in cotton dust exposed workers. With continuous exposure, progression of disease and pulmonary dysfunction will happen. In this study, we assessed the effect of co...
