COPD Clinical Trials & Lung Care Advances

Chronic obstructive pulmonary disease (COPD) is a main source of world-wide mortality and disability. On average ∼5– 15% of adults in industrialized nations have COPD characterized by spirometry. In 1990, COPD was determined as at the twelfth position worldwide reason for consolidated mortality and disability but it is expected to be the fifth cause by 2020COPD has an chronic long-lasting course with irreversible decrease of forced expiratory volume in one second (FEV1), increasing nearness of dyspnoea and other respiratory manifestations, and dynamic decay of wellbeing status. After analysis the 10-yr survival rate is ∼50% with more than 33% of patients dying because of respiratory inadequacy.
