Effects of Vojta Therapy on the Forced Vital Capacity and Forced Expiratory Volume at One Second in Young Male Smokers: A Single-Subject Design

Sources 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...

Obstructive ventilatory defect with normal forced expiratory volume in one second/vital capacity ratio.

Comparison 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...

Use of forced vital capacity and forced expiratory volume in 1 second quality criteria for determining a valid test

The 2005 American Thoracic Society (ATS)/European Respiratory Society (ERS) spirometry guidelines define valid tests as having three acceptable blows and a repeatable forced vital capacity (FVC) and forced expiratory volume in 1 s (FEV1). The aim of this study was to determine how reviewer and computer-determined ATS/ERS quality could affect population reference values for FVC and FEV1. Spirome...

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...
