Chronic obstructive pulmonary disease (COPD) is a type of progressive lung disease characterized by chronic respiratory symptoms and airflow limitation. [8] GOLD 2024 defined COPD as a heterogeneous lung condition characterized by chronic respiratory symptoms (dyspnea or shortness of breath, cough, sputum production or exacerbations) due to abnormalities of the airways (bronchitis ...
COPD is defined as a forced expiratory volume in 1 second divided by the forced vital capacity (FEV1/FVC) that is less than 0.7 (or 70%). [8] The residual volume, the volume of air left in the lungs following full expiration, is often increased in COPD, as is the total lung capacity, while the vital capacity remains relatively normal.
An early morning sample is preferred. [7] E-nose showed the ability to smell the cause of the exacerbation. [8] The definition of a COPD exacerbation is commonly described as "lost in translation", [9] meaning that there is no universally accepted standard with regard to defining an acute exacerbation of COPD. Many organizations consider it a ...

Respiratory diseases, or lung diseases, [1] are pathological conditions affecting the organs and tissues that make gas exchange difficult in air-breathing animals. They include conditions of the respiratory tract including the trachea, bronchi, bronchioles, alveoli, pleurae, pleural cavity, the nerves and muscles of respiration.
For example, Asbestosis. Radiation fibrosis, usually from the radiation given for cancer treatment. Certain drugs such as amiodarone, bleomycin and methotrexate. As a consequence of another disease such as rheumatoid arthritis. Hypersensitivity pneumonitis due to an allergic reaction to inhaled particles.
