Effort 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 کاملSources of variation in forced expiratory volume in one second and forced vital capacity.
Published prediction equations for lung function differ considerably, but the components of population variation responsible for the differences are unknown. Data were analysed for 6,323 never-smoking adults who did not report wheeze or asthma, from 42 centres participating in the European Community Respiratory Health Survey. Means and components of variance were estimated for males and females...
متن کاملNormal values of forced vital capacity (FVC), forced expiratory volume (FEV 1-0), and peak flow rate (PFR) in children.
In children, the respiratory tract is probably more often affected by disease than any other system of the body. In spite of this, quantitative methods of evaluation are seldom used outside special respiratory units. No clinician would manage a patient with potential renal failure without laboratory aids, even if it were only an estimation of the blood urea, but he would seldom give children wi...
متن کاملUncertainties in the expected value for forced expiratory volume in one second after surgery.
The purpose of this study is to understand better the reasons for the frequent unreliability of the expected value for the forced expiratory volume in one second (FEV1) in predicting surgical results after pneumonectomy. Measurement of FEV1 was performed in 159 patients before and after removal of one lung. Only 41 of the postoperative values for FEV1 differed from predicted values by less than...
