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 ...

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

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.

Results Pulmonary function tests were evaluated from 311 athletes, across 20 Olympic and 13 paralympic sports (48% female, mean +/- SD age: 25 ± 5 years). Supra-normal FEV1 and FVC values were ...

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 ...

Lung function was evaluated as forced expiratory volume in 1 second (FEV1), FVC, and FEV1/FVC ratio, measured using spirometry at baseline, and postbronchodilator values of these measures were ...
