An acute exacerbation of chronic obstructive pulmonary disease, or acute exacerbations of chronic bronchitis ( AECB ), is a sudden worsening of chronic obstructive pulmonary disease (COPD) symptoms including shortness of breath, quantity and color of phlegm that typically lasts for several days. It may be triggered by an infection with bacteria ...
3.2 million (2019) [ 3] Chronic obstructive pulmonary disease ( COPD) is a type of progressive lung disease characterized by long-term 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 ...
Obstructive lung disease is a category of respiratory disease characterized by airway obstruction. Many obstructive diseases of the lung result from narrowing (obstruction) of the smaller bronchi and larger bronchioles, often because of excessive contraction of the smooth muscle itself. It is generally characterized by inflamed and easily ...
Respiratory failure results from inadequate gas exchange by the respiratory system, meaning that the arterial oxygen, carbon dioxide, or both cannot be kept at normal levels. A drop in the oxygen carried in the blood is known as hypoxemia; a rise in arterial carbon dioxide levels is called hypercapnia. Respiratory failure is classified as ...

Bronchial hyperresponsiveness is a hallmark of asthma but also occurs frequently in people with chronic obstructive pulmonary disease (COPD). [2] In the Lung Health Study, bronchial hyperresponsiveness was present in approximately two-thirds of patients with non-severe COPD, and this predicted lung function decline independently of other ...
Asthma-COPD overlap. Asthma-Chronic Obstructive Pulmonary Disease (COPD) Overlap (ACO), also known as Asthma-COPD Overlap Syndrome (ACOS) is a chronic inflammatory, obstructive airway disease in which features of both asthma and COPD predominate. Asthma and COPD were once thought of as distinct entities, however in some, there are clinical ...
Pulmonary veno-occlusive disease ( PVOD) is a rare form of pulmonary hypertension caused by progressive blockage of the small veins in the lungs. [ 2] The blockage leads to high blood pressures in the arteries of the lungs, which, in turn, leads to heart failure. The disease is progressive and fatal, with median survival of about 2 years from ...
