Serum respiratory virus antibodies: predictor of reduced one-second forced expiratory volume (FEV1) in Norwegian adults.
BACKGROUND The purpose of this cross-sectional study was to investigate whether the presence of serum complement antibodies was associated with reduced one-second forced expiratory volume (FEV1) in adults. METHODS From a stratified random sample of 18-73 year old adults, we performed measurements of serum complement fixing virus antibodies against influenza type A and B, parainfluenza type 1,...
متن کاملComparison of forced expiratory volume in one second (FEV1) among asymptomatic smokers and non-smokers.
OBJECTIVE To compare the forced expiratory volume in first second (FEV1) among asymptomatic smokers and non-smokers for evaluating the effect of cigarette smoking on healthy subjects. METHODS This was a Comparative cross-sectional study done at military hospital Rawalpindi from June 2006 till June 2007. Two hundred male subjects, 100 smokers and 100 non-smokers were included using non-probabi...
متن کاملEffort and the forced expiratory volume in one second (FEV).
1. The relationship between volumes expired and the maximum intrathoracic pressures developed within the first second of expiration was examined in a group of healthy subjects and patients with airways obstruction who exhaled with varying degrees of effort. 2. The body plethysmographic method was used to ensure that expirations started from total lung capacity. 3. Three different types of volum...
متن کاملForced expiratory volume in one second: why dichotomise?
Numerous epidemiological surveys have tried to evaluate the effects of exposures relevant to pulmonary disease.' A number of studies have analysed forced expiratory volume in one second (FEVI) using linear regression analysis, thus enabling adjustment for age, height, and sex as well as potential confounding variables. Within the last few years, studies analysing dichotomous FEV, variables with...
متن کاملThe changes in airways structure associated with reduced forced expiratory volume in one second.
We compared the structure of the membranous and respiratory bronchioles of resected lungs from 111 patients with a normal predicted forced expiratory volume in one second (FEV1) to the structure of these airways from 45 patients with an FEV1 reduced below the 95% confidence limits for height and age. Membranous and respiratory bronchioles of less than 2 mm in internal diameter were counted and ...
