This device measures lung function and records the results, which are also displayed on a graph ... (FVC). The test also measures how much you exhaled in the first second, known as FEV1.

Around 20% to 25% of individuals with rapidly declining FEV1/FVC trajectories experienced wheezing and usual ...

1 Overall, mean ± SD of FVC was 41.6 ± 31.0%, FEV1 was 42.0 ± 30.0%, and FEV1/FVC was 95.8 ± 18.3%. Spirometry parameters varied among the 3 institutions, as follows. 1 Other parameters were ...

Participants with higher forced vital capacity, indicating better lung function, were less likely to develop heart disease, diabetes, and stroke over 10 years.

Supra-normal FEV1 and FVC values were identified in 14% and 9% of the cohort respectively; there was an FEV1 and FVC positive median bias (standard residual [SR]) of 0.33 and 0.60 respectively, when ...
