The guideline-recommended FEV1:FVC value of less than 0.70 is the optimal cutoff for the diagnosis of clinically significant chronic obstructive pulmonary disease (COPD), researchers say. The study, ...

Forced expiratory volume in 1 second (FEV1) measures how much air you can forcefully exhale in one second. A low FEV1 suggests a breathing obstruction caused by conditions like chronic obstructive ...
