Background: Spirometric diagnosis of chronic obstructive pulmonary disease (COPD) is based on the ratio of forced expiratory volume in 1 second (FEV1)/vital capacity (VC), either as a fixed value 1/VC ratio in a general population setting. The second aim was to evaluate the characteristics of...
There are other aspects to pulmonary testing, such asfunctional residual capacity (FRC), which measures air in your lungs after exhaling. You may need other tests if your pulmonary condition has been difficult to diagnose or if you are not improving as expected. Your whole battery of tests cou...

The FVC is the forced vital capacity. It requires that the subject make a maximal inspiration to TLC, then make a maximal forced expiratory effort, leaving only the RV. In a normal subject, the FEV1/FVC is greater than 0.8; patients with obstructive lung disease, such as asthma or COPD,...

Rationale: Chronic obstructive pulmonary disease (COPD) is thought to result in rapid and progressive loss of lung function usually expressed as mean values for whole cohorts. Objectives: Longitudinal studies evaluating individual lung function loss and other domains of COPD progression are needed. Metho...
