The Clinical Role of Changes of Maximum Expiratory Flow at 25% and 50% of Vital Capacity before and after Bronchodilator Reversibility Test in Diagnosing Asthma.

Changes of maximum expiratory flow at 25% and 50% of vital capacity (MEF and MEF, respectively), and predominant parameters indicating small airways function in asthmatics before and after bronchodilator (BD) reversibility test have been less interpreted. Our study aimed to investigate the clinical role of changes of MEF and MEF before and after BD reversibility test in diagnosing asthma. Forced expiratory volume in the first second (FEV), MEF, and MEF were measured before and after BD reversibility test in 207 asthmatic patients using standard process.

Application of Inflammatory Markers in Induced Sputum in Stable Chronic Obstructive Pulmonary Disease Patients with Positive Bronchodilation Tests.

Positive bronchodilation (BD) tests can be noticed in some stable chronic obstructive pulmonary disease (COPD) patients. The characteristics of airway inflammation in this entity remain unclear. Our study aimed to identify the characteristics of airway inflammation in stable COPD patients with positive BD tests.
