Spirometry test There is significant disparity in the ratios for postbronchodilator FEV1/FEV6 and FEV1/FVC %, and this disparity is very pronounced in women. Disclosure: One study author declared ...

Abstract: Preserved ratio impaired spirometry (PRISm) is a pulmonary function pattern characterized by a forced expiratory volume in one second (FEV1) to forced vital capacity ratio greater than 0.70, ...

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, ...

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.

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 ...
