For many clinicians, the use of a bronchodilator drug in COPD seemed to be contradictory as the immediate improvement in forced expiratory volume in 1 s (FEV1) and objective measure of its efficacy bear little, if any, relationship to the patient's self- reported symptoms. The reasons for ...

STUDY OF BODE INDEX AS A PREDICTOR OF HOSPITALISATION IN PATIENTS WITH COPD The following parameters of the pulmonary function test were measured: (a) forced expiratory volume in the first second (FEV1) pre- and postadministration of a bronchodilator, (b) forced vital capacity (FVC), and (c...
Spirometry was performed in a population-based study (n=2,256) covering an age range of 41–90 years. COPD was spirometrically determined either by a fixed ratio (FR) of <0.7 for forced expiratory volume in 1 second (FEV1)/forced vital capacity (FVC) or by FEV1/FVC below the lower ...
People with COPD experience a more rapid decline in what is called forced expiratory volume, or FEV. FEV is the maximum volume of air that can be exhaled within a specified time period, starting from maximal inhalation. A subscript indicates the time period in seconds. For example, FEV1is th...
TUESDAY, July 9, 2019 (HealthDay News) -- Use of a threshold of airflow obstruction of forced expiratory volume in one second:forced vital capacity (FEV1:FVC) of 0.70 discriminates chronic obstructive pulmonary disease (COPD)-related hospitalization and mortality, according to a study published ...

The annual rate of decline in forced expiratory volume for 1 second (FEV1) has been researchers' gold standard as an objective measure for progression of chronic obstructive pulmonary disease (COPD). Inhaled corticosteroids (ICS) do not consistently have a statistically significant impact on FEV1 dec...

Somepeople with COPDnearly double one measure of lung function called forced expiratory volume in one second (FEV1) by week six. While these improvements may not be as dramatic moving forward, they tend to continue gradually in people with mild to moderate COPD and remain relatively stable for ...
