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, ...

In a large US cohort study, pre-pandemic severe obstructive lung function, as measured by spirometry, was linked to more than a twofold increased risk for severe COVID-19. Researchers analyzed the ...
