Assessment of variable obstruction by forced expiratory volume in 1 second, forced oscillometry, and interrupter technique

Allergy and Asthma Proceedings, 2007
The aim of this study was to evaluate the presence and the degree of reversible airflow obstruction as detected by forced expiratory volume in 1 second (FEV1), forced oscillometry (FOT), and interrupter technique (resistance measured by the ...

The relaxed expiratory volume and forced inspiratory volume after bronchodilators

British Journal of Diseases of the Chest, 1970
Summary To assess the value of various ventilatory tests in showing response to a bronchodilator, ninety-two patients with chronic bronchitis, some of whom had emphysema, were studied. The FEV 1·0 , REV 1·0 , VC, FEV 1·0 /VC% and the FIV 1·0 were measured before and after the administration of an isoprenaline sulphate aerosol.

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.

Shape of Forced Expiratory Flow-Volume Curves in Infants

American Review of Respiratory Disease, 1988
Abstract An inflatable cuff was used to generate partial forced expiratory flow-volume (FEFV) curves in 36 infants with and without obstructive airway disease. Curves were recorded in each infant over a range of compression pressures as high as and exceeding the pressure required for the maximal partial FEFV curve.

Characteristics associated with rapid decline in forced expiratory volume

Annals of Epidemiology, 1996
Cigarette smoking is known to accelerate decline of pulmonary function; however, the role of other factors is less clear. Characteristics of individuals who experienced rapid decline in forced expiratory volume in 1-sec (FEV1) were examined in 4451 Japanese-American men from the Honolulu Heart Program who were aged 45 to 68 years at baseline (1965-1968)

Forced expiratory flows and lung volumes in normal infants

Pediatric Pulmonology, 1993
AbstractForced expiratory flows at functional residual capacity (VmaxFRC) by the rapid compression technique and functional residual capacity (FRC) by the helium dilution technique were assessed in 112 normal infants with a mean age of 10.7 months (range, 1.0–31.0).

The forced expiratory volume after hyperventilation in bronchitis and asthma

British Journal of Diseases of the Chest, 1968
Summary Changes in F.E.V. one minute after voluntary hyperventilation and after hyperventilation induced by carbon dioxide rebreathing and by aminophylline, were studied in asthmatic, bronchitic and normal subjects. There was a small but statistically significant fall in the mean of the F.E.V.
