Maximum expiratory flow rates like forced expiratory volume
in 1 sec ([FEV.sub.1]), [FEV.sub.1]/FVC (per cent), forced expiratory flow at 50 per cent of FVC, forced expiratory flow at 75 per cent of FVC and forced expiratory flow at 25-75 per cent of FVC were normal or near normal (Table I).
Secondary endpoints included effects on lung function parameters, as measured by residual volume, forced expiratory volume
in once second, and forced vital capacity.

After noting their gender, age, height and weight, the pulmonary function test measures, force vital capacity, forced expiratory volume
in 1 second and peak expiratory flow rate were taken.
Forced vital capacity (FVC) and Forced Expiratory Volume
Other lung parameters like tidal volume ([V.sub.T] or T.V), Inspiratory reserve volume (I.R.V), Expiratory reserve volume (E.R.V), Vital capacity (V.C), Forced expiratory volume
in first second ([FEV.sub.1]%) were recorded using the Benedict-Roth Spirometer.
In the six trials, efficacy was measured based on changes in forced expiratory volume
More specifically, the purpose of this study was to compare forced vital capacity (FVC), forced expiratory volume
in one second as a percent of forced vital capacity (FEV1/FVC%), maximum inspiratory pressure (MIP), and maximum expiratory pressure (MEP) values obtained during standing, sitting, forward sitting, supine, and prone positions.
Lung function assessment included forced vital capacity (FVC), forced expiratory volume
and peak expiratory flow (PEF).
Study participants had a mean baseline forced expiratory volume
in 1 second of 33% of predicted, indicative of very severe COPD.
