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, ...
