Early detection of obstructive lung disease by analysis of maximal expiratory flow-volume curves.

Chest, 1973
The clinical application of maximum expiratory flow-volume (MEFV) curves in making an early diagnosis of emphysema and disease of small airways is reviewed. Previous analysis of the physiologic basis of the forced expiratory spirogram indicates that the MEFV curve contains the same information as the volume-time plot.

The Maximal Expiratory Flow-Volume Curve in Normal Subjects in India

Chest, 1986
Data on pulmonary function, with particular reference to flow-volumes, were obtained in 760 normal healthy Indians in Bombay, who had never smoked and who had no symptom or history of cardiorespiratory disease. Prediction equations were derived for spirometric parameters and for maximal expiratory flows. The maximal expiratory flow-volume curves showed

Assessment of Ventilatory Performance of Athletes Using the Maximal Expiratory Flow-Volume Curve

International Journal of Sports Medicine, 1986
We carried out a maximum expiratory flow-volume curve (MEFV) and a spirometric recording with 67 athletes of different ages (15-27 years) and disciplines (rowers, kayakists, cyclists, swimmers) and with 20 adult and 13 adolescent nonathletic controls of matching ages.

Quantifying the Shape of the Maximal Expiratory Flow–Volume Curve in Mild COPD

Respiratory Physiology and Neurobiology, 2015
Maximal expiratory flow-volume (MEFV) curve evaluation using absolute and percent predicted values of flow and volume are used to diagnose respiratory disease, but the shape of the curve is rarely used. Three mathematical methods were used to quantify shape of MEFV curves in subjects with mild COPD (n=19) and matched healthy controls (n=15). Those with

Are There Any Impairments of Maximal Expiratory Flow-Volume Curves by Passive Smoking?

, 1990
Impairments of lung function are generally found more often in active smokers than in non-smokers. Thus, the question arises whether the passive inhalation of tobacco smoke may also cause such an effect.

Variability of Maximal Expiratory Flow-Volume Curve in Young Volley Players

Respiration, 2009
In order to assess the variability of forced expiratory flows, 15 male players (age 16–19 years, height 182–201 cm) of the Italian National Junior Volley team were studied twice with the pneumotachygraph of the computerized Hewlett-Packard Pulmonary System.

Influence of matching volume on reproducibility of maximal expiratory flow-volume curves.

Bulletin europeen de physiopathologie respiratoire, 1984
We examined the influence of "matching volume" on intrasubject variability of the descending limb of maximal expiratory flow-volume (MEFV) curves on air and helium-oxygen (He) in 18 healthy subjects and 28 patients with airflow limitation. Duplicate forced expirations were analysed according to four methods of alignment.

Maximal expiratory flow volume curve in quarry workers.

Indian journal of physiology and pharmacology, 2002
Maximal Expiratory Flow Volume (MEFV) curves were recorded with a computerized Spirometer (Med Spiror). Forced Vital Capacity (FVC), Forced Expiratory Volumes (FEV), mean and maximal flow rates were obtained in 25 quarry workers who were free from respiratory disorders and 20 healthy control subjects.

[Relevance of the maximal expiratory flow-volume curve in an epidemiological study].

Zeitschrift fur Erkrankungen der Atmungsorgane, 1983
In an epidemiological study a random sample (1,554 males aged 35 to 54 years) of the population of a hydrogen chloride air-polluted area was investigated by means of the modified MRC questionnaire and maximal expiratory flow-volume curves. The MEF-values were dependent on age and height.

Spirometry and Maximal Expiratory Flow-Volume Curve Reference Standards for Polynesian, European, and Chinese Teenagers

Chest, 1988
Lung function was compared and reference standards were determined in 1,007 Polynesian, European, and Chinese teenagers attending school in Tahiti (517 boys, 490 girls; mean age, 14.4 years). Spirometric study results and maximal expiratory flow-volume curves were measured using techniques recommended by the American Thoracic Society.
