Measurement of Forced Expiratory Flows and Lung Volumes
NeoReviews, 2004After completing this article, readers should be able to: 1. Describe the information that measurements of forced expiratory flow can provide in spontaneously breathing and mechanically ventilated infants. 2. Delineate how lung volume can be measured.

The forced expiratory volume after hyperventilation in bronchitis and asthma
British Journal of Diseases of the Chest, 1968Summary 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.

Peripheral Airways Resistance, Static Recoil and the Forced Expiratory Volume
Clinical Science, 19721. The forced expiratory volume (FEV0·75) was measured at increasing mouth pressures in twenty-seven patients with obstructive airways disease. Attempts were made to divide the patients on clinical grounds into emphysematous, bronchitic or asthmatic categories; there was no evidence from the (FEV/mouth pressure) plots that their airways functioned ...

The forced expiratory volume–time curve estimation using the electrocardiogram
Computers in Biology and Medicine, 1998The feasibility of estimating the forced expiratory volume-time curve from the amplitude modulation of the electrocardiogram was studied using a numerical torso model and ECG signal processing. A two dimensional numerical model of the torso was solved for the maximum expiration and inspiration to study the changes in the surface potential as a result ...

Air pollution and the forced expiratory volume in chronic bronchitis
Irish Journal of Medical Science, 1965Fifteen male patients suffering from chronic bronchitis with partially reversible obstructive lung disease, had forced expiratory volume examinations at roughly two-weekly intervals from November, 1963, to May, 1964. Eight of the patients took continuous antibiotics (Methacycline) during this period.

Effect of Effort versus Volume on Forced Expiratory Flow Measurement
American Review of Respiratory Disease, 1988Recently, the validity of the American Thoracic Society (ATS) standards for selection of spirometric test results has been questioned based on the finding of inverse dependence of FEV1 on effort. I carried out a study to determine how the test results of FEV1 and FEF25-75 are affected by use of effort-based criteria (highest PEFR) as compared with the ...
