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, ...

Upon implementing race-neutral equations, there was a decrease in z scores among Black children for forced expiratory volume in 1 second (FEV1; mean difference −0.814, 95% CI −0.823 to −0.806, P<0.001 ...

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 ...

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 ...
