Reproducibility of forced expiratory flow and volume measurements in infants with bronchiolitis

Pediatric Pulmonology, 1999
The end-tidal rapid thoracoabdominal compression (ETRTC) technique is an established method for lung function testing in infancy. Previous work in healthy infants, however, has shown that measurements with the newly developed raised volume rapid thoracoabdominal compression (RVRTC) technique are more reproducible than those with the ETRTC technique.

Peripheral Airways Resistance, Static Recoil and the Forced Expiratory Volume

Clinical Science, 1972
1. 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, 1998
The 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 ...

Effect of Effort on Measurement of Forced Expiratory Volume in One Second

American Review of Respiratory Disease, 1987
Abstract The American Thoracic Society recommends that the largest FEV1 be reported from a set of forced expiratory vital capacity maneuvers performed with maximal expiratory effort. However, increased expiratory effort can decrease the FEV1.
