Chronic obstructive pulmonary disease (COPD) is a common disease usually treated in general practice, especially in the early stages.1 The recently published British Thoracic Society guidelines encourage a systematic approach to the management of COPD as is widely used in asthma.2 Lung function ...
Conclusion: FEV1% and FEV1/FVC% have a definite role in defining various stages of COPD. Hence, it is an automatic choice for identifying and there by classifying various stages of COPD.doi:10.7439/ijbr.v3i10.776Shivanand K GManjunath M L...

FEV1/FVC ratio and indexvalues below 70%are typical for chronic obstructive pulmonary disease - COPD(see:the BODE index calculator). We can distinguish a few stages of COPD, designated by the Tiffeneau index and FEV1 values: I— Mild, with FEV1/FVC < 70% and FEV1 > 80% predicted; ...
Clinical Pearl of the Day: COPD and forced exhalation volume in 1 second (FEV1)/forced vital capacity (FVC). FEV1 and FEV1/FVC can determine the stage severity for COPD disease. Explanation The above stages can be determined based on the FEV1/FVC ratio, as well as FEV1 numbers. FEV1: vo...
The FEV1/FVC ratio is defined as a fixed ratio used to assess airflow obstruction in the lungs, particularly in the context of Chronic Obstructive Pulmonary Disease (COPD). AI generated definition based on: Kendig's Disorders of the Respiratory Tract in Children (Ninth Edition), 2019 ...
This compound prognostic index predicts mortality risk in COPD patients and was initially developed in a large cohort of patients at various stages of COPD106. In this cohort, patients who died within 1 year achieved significantly shorter 6MWT distances compared with survivors (mean ± standard...
2 Further, in advanced stages of COPD and ACO, spirometry, which requires forced expiration, places a burden on the patient. The forced oscillation technique (FOT) is a method for noninvasively measuring respiratory system resistance (Rrs) and reactance (Xrs) during tidal breathing. It provides ...

The aim of this study was to identify factors that separate healthy subjects with reduced FEV1/FVC from subjects ...
