Researchers say that using the lower limit of normal (LLN) of the forced expiration volume in 1 second (FEV1)/forced vital capacity (FVC) ratio improves risk stratification in patients with chronic ...

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 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 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 ...
