In medicine, an exacerbation is the worsening of a disease or an increase in its symptoms. [1] Examples includes an acute exacerbation of chronic obstructive pulmonary disease and acute exacerbation of congestive heart failure .
Airway inflammation is increased during the exacerbation resulting in increased hyperinflation, reduced expiratory air flow and decreased gas exchange. [1] [2] Exacerbations can be classified as mild, moderate, and severe. [3] As COPD progresses, exacerbations tend to become more frequent, the average being about three episodes per year. [4]
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 ...
Inflammation for example has a recognised group of cardinal signs and symptoms, [44] as does exacerbations of chronic bronchitis, [45] and Parkinson's disease. In contrast to a pathognomonic cardinal sign, the absence of a sign or symptom can often rule out a condition. This is known by the Latin term sine qua non.
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.
