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 ...

Spirometry is a standard test doctors use to determine how well your lungs function. A score that measures airflow into and out of your lungs can help diagnose COPD and determine the best treatments.

This study evaluates the predictive power of CT-derived functional imaging (CTFI) combined with forced expiratory volume in 1 second (FEV1) for 10-year all-cause mortality in COPD patients. We ...

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, ...

A spirometry is a pulmonary function test that measures how much air a person breathes out, and how quickly. Pulmonary function tests measure how well the lungs are working. It is an office-based ...

Chronic obstructive pulmonary disease (COPD) is a chronic lung condition characterized by shortness of breath and a chronic cough. Although there’s no cure for this progressive lung disease, it can be ...

In the 2015 update of its strategy for asthma management and prevention the “Global Initiative for Asthma” (GINA) advises to consider symptoms and lung function parameters separately, with lung ...

The results of spirometry test can be interpreted to provide valuable information about the function of the lungs and respiratory system and guide diagnostic and treatment decisions. There are various ...

Please provide your email address to receive an email when new articles are posted on . Factors associated with FEV1 included baseline fractional exhaled nitric oxide, response to a characterizing ...

Better lung function, expressed as higher forced vital capacity (FVC), is associated with a reduced risk for the onset of heart disease, diabetes, and stroke over a follow-up period of approximately ...

Good technique is essential when undertaking spirometry tests, and correct interpretation of the results is important to avoid making an incorrect diagnosis. Lung function results are reported as ...
