OBJECTIVE To evaluate the effectiveness and onset of action of formoterol delivered by dry-powder inhaler in reversing methacholine-induced bronchoconstriction. METHODS Patients presenting a drop in forced expiratory volume in one second > 20% after methacholine inhalation were included. A total of 84 patients were evaluated. All of the participating patients presented respiratory symptoms of...

The study was conducted on 100 pregnant women in third trimester of uncomplicated pregnancy (Test group) and 100 age-matched non-pregnant women (Control group) in the age group of 25 to 35 years. Pulmonary function test parameters FVC, FEV1, PEFR and FEF25-75% recorded using Medspiror. The FEV1/FVC ratio was calculated. All parameters except FEV1/ FVC ratio were found to decline in the Test gro...

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...

Slow spirometry and forced spirometry (flow volume loop) are often used to measure clinically relevant lung volumes and forced expiratory and inspiratory flows. Dynamic parameters, such as forced expiratory volumes in one second (FEV1) or forced vital capacity (FVC) and static lung volumes, such as expiratory reserve volume (ERV), inspiratory capacity (IC) and inspiratory vital capacity (IVC) c...

c-reactive protein (crp) is an acute-phase protein synthesized predominantly by the hepatocytes in response to tissue damage or inflammation. levels of acute-phase proteins rise rapidly, during infection and after injury. we take up the study to correlate serum crp levels with other important predictive markers of outcome in copd. patient with stable copd (no exacerbation in the last two months...
