Rate of forced expiratory volume in one second and forced expiratory volume in one second/forced vital capacity decline among Indonesian patients with chronic obstructive pulmonary disease after a year of treatment

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.

Relationship between serum vitamin D and forced expiratory volume in patients with chronic obstructive pulmonary disease (COPD)

Background: Vitamin D deficiency seems to be associated with pulmonary function deterioration. The present study was designed to investigate the relationship between serum vitamin D and forced expiratory volume in patients with chronic obstructive pulmonary disease (COPD). Methods: From September 2011 to April 2012 eighty consecutive patients with COPD presented to an outpatient clinic of Babo...

Forced expiratory volume in one second can predict SYNTAX score in patients with chronic obstructive pulmonary disease.

BACKGROUND The SYNTAX score is an angiographic score that predicts coronary artery disease (CAD) complexity. It has been shown to be useful for decision making about percutaneous coronary intervention or coronary artery bypass grafting among patients with CAD. Higher SYNTAX scores are indicative of more complex disease. Chronic obstructive pulmonary disease (COPD) is characterised by limitation...

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...
