Predictive nomograms for forced expiratory volume, forced vital capacity, and peak expiratory flow rate, in Chinese adults and children

British Journal of Diseases of the Chest, 1983
A survey of three indices of ventilatory capacity, forced expiratory volume in 1 second (FEV1), forced vital capacity (FVC) and peak expiratory flow rate (PEFR), was undertaken on 3490 Chinese inhabitants of Hong Kong. Nomograms have been constructed for the prediction of these three indices for subjects between the ages of 5 and 75 years.

Chronic Bronchitis and Decreased Forced Expiratory Flow Rates in Lifetime Nonsmoking Grain Workers

Chest, 1981
To determine whether clinical symptoms and pulmonary function abnormalities were more common in lifetime nonsmoking grain elevator workers exposed to grain dust than in lifetime nonsmoking community control subjects who were not occupationally exposed to dust, we obtained an occupational health questionnaire, spirometric variables, and flow-volume ...

The forced expiratory volume and the peak expiratory flow rate in pneumoconiosis

British Journal of Diseases of the Chest, 1966
Summary One hundred and sixty men with coal-miner's pneumoconiosis were studied in two groups to ascertain whether a good correlation existed between the F.E.V. 1 and the P.E.F.R. The first group consisted of 100 miners without chronic bronchitis and the second of 60 miners with chronic bronchitis. Correlation was good in both groups.

Evaluation of a New Ambulatory Spirometer for Measuring Forced Expiratory Volume in One Second and Peak Expiratory Flow Rate

American Review of Respiratory Disease, 1993
A new pocket-sized ambulatory spirometer (meter) that measures FEV1 and PEFR was evaluated. The meter determines flow rate (V) from the differential pressure (P1-P2) across a sharp-edged orifice (V alpha square root of[P1-P2]). Ten meters were evaluated for accuracy using a computerized syringe to deliver the 24 ATS-recommended waveforms and nine ...

Comparison of Maximal Midexpiratory Flow Rate and Forced Expiratory Flow at 50% of Vital Capacity in Childrena

Chest, 2003
The mid-portion of the maximal expiratory flow-volume (MEFV) curve is often described by values of the mean forced expired flow as lung volume decreases from 75% to 25% of vital capacity (ie, forced expiratory flow, midexpiratory phase [FEF(25-75)]).
