The term "chronic bronchitis" was used in previous definitions of COPD but is no longer included in the definition. [10] [32] [33] The term is still used clinically. [34] While both chronic bronchitis and emphysema are often associated with COPD, neither is needed to make the diagnosis. [34]
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.
Chronic mucus hypersecretion results in the chronic productive cough of chronic bronchitis, [19] and is generally synonymous with this. [20] Excessive mucus can narrow the airways, limit airflow, and accelerate a decline in lung function. [10]
Types of obstructive lung disease include asthma, bronchiectasis, bronchitis and chronic obstructive pulmonary disease (COPD). Although COPD shares similar characteristics with all other obstructive lung diseases, such as the signs of coughing and wheezing , they are distinct conditions in terms of disease onset, frequency of symptoms, and ...

[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 ...

Ventilator-associated tracheobronchitis is a hospital-acquired infection usually contracted in an intensive care unit when a mechanical ventilator is used. [1] The insertion of a tracheal tube can cause an infection in the trachea which then colonises and spreads to the bronchi.
