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, ...

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.

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, ...

Pulmonary function tests are a group of noninvasive breathing tests that measure how much air your lungs can hold, how quickly you can move air in and out and how efficiently your lungs transfer ...

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 ...

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 ...

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 ...

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 ...
