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

Two distinct groups were identified, those with normal maximum voluntary ventilation (MVV) (> 80% predicted) and those with low MVV. Both inspiratory and expiratory flow rates (FVC, FEV1 ...

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.

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 ...

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 ...
