Discover how COPD and preserved ratio impaired spirometry (PRISm) findings accelerate frailty progression, based on a ...

Other lung volumes are normal. FER: Forced expiratory ratio; FEV 1: Forced expiratory volume in 1 s; FRC: Functional residual capacity; FVC: Forced vital capacity; KCO: Carbon monoxide diffusion ...

We modeled FEV1 and FVC as secondary outcomes to evaluate the association between pulmonary function ... It may be that monitoring dd-cfDNA over time is more sensitive than spirometry in identifying ...

A mix of contradictory data shows a reduction in the ratio of the forced expiratory volume in the first 1 second to the forced vital capacity (FEV 1 /FVC), an increase in FVC, and changes in ...
