The obstruction was based on post-bronchodilator FEV1/FVC < lower limit of normal (LLN) and <0.70 (fixed ratio). A total of 2,352 subjects (54% male, post-bronchodilator FEV1 76.5% predicted) were ...

Combined treatment with bronchodilator drugs and steroids resulted in a mean increase in vital capacity and first-second volume of almost 50 per cent of the pretreatment value.

Conclusions Inhaled dual bronchodilator therapy did not decrease respiratory symptoms in symptomatic, tobacco-exposed persons with preserved lung function as assessed by spirometry.

Notably, the likelihood for bronchodilator responsiveness per the 2005 definition significantly went down with testing in autumn vs. winter (aOR = 0.67; 95% CI, 0.48-0.92), according to the study.

NEW ORLEANS — Use of spirometry with bronchodilator testing can help reduce overdiagnosis of COPD as well as help differentiate COPD from asthma and asthma-COPD overlap syndrome, researchers ...

PEF failed to consistently reflect FEV1 improvements after bronchodilation, indicating that handheld spirometry may better ...

Bronchodilators are front-line weapons against asthma and chronic obstructive pulmonary disorder. The search continues for next-generation dilators, which so far has largely produced compounds that ...

Each patient's bronchodilator responsiveness (BDR) was determined by three measures: absolute change in the volume of air exhaled during a forced breath in one second (FEV1) (BDRABS); change as ...

HealthDay News — Patients are more likely to have positive bronchodilator responsiveness in the morning and in winter months, according to a study published online March 11 in Thorax. Ben Knox ...
