  2. Bronchiectasis - Wikipedia

    en.wikipedia.org/wiki/Bronchiectasis

    Bronchiectasis is a disease in which there is permanent enlargement of parts of the airways of the lung. [5] Symptoms typically include a chronic cough with mucus production. [ 3 ] Other symptoms include shortness of breath , coughing up blood , and chest pain. [ 2 ]

  3. Respiratory disease - Wikipedia

    en.wikipedia.org/wiki/Respiratory_disease

    Asthma, chronic bronchitis, bronchiectasis and chronic obstructive pulmonary disease (COPD) are all obstructive lung diseases characterised by airway obstruction.This limits the amount of air that is able to enter alveoli because of constriction of the bronchial tree, due to inflammation.

  4. Chronic obstructive pulmonary disease - Wikipedia

    en.wikipedia.org/wiki/Chronic_obstructive...

    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 ...

  5. Obstructive lung disease - Wikipedia

    en.wikipedia.org/wiki/Obstructive_lung_disease

    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.

  6. Emphysema - Wikipedia

    en.wikipedia.org/wiki/Emphysema

    Trapped air can also develop in other tissues such as under the skin, known as subcutaneous emphysema. Orbital emphysema is the trapping of air in the orbit; a type of this is palpebral emphysema that affects just the eyelids. [62] Emphysematous gastritis is the presence of air in the stomach wall, usually caused by a bacterial infection. [63]

  7. Pulmonary edema - Wikipedia

    en.wikipedia.org/wiki/Pulmonary_edema

    Pulmonary edema (British English: oedema), also known as pulmonary congestion, is excessive fluid accumulation in the tissue or air spaces (usually alveoli) of the lungs. [1] This leads to impaired gas exchange , most often leading to shortness of breath ( dyspnea ) which can progress to hypoxemia and respiratory failure .

  8. Lung cavity - Wikipedia

    en.wikipedia.org/wiki/Lung_cavity

    Areas of emphysema are abnormal, air-filled spaces that usually do not have visible walls, [5] and bullae are very thin walled (<1 mm). [2] Cystic bronchiectasis is irreversible bronchial dilation, which is permanent widening of the bronchioles (small airways) in the lung. [2]

  9. Peribronchial cuffing - Wikipedia

    en.wikipedia.org/wiki/Peribronchial_cuffing

    Peribronchial cuffing, also referred to as peribronchial thickening or bronchial wall thickening, is a radiologic sign which occurs when excess fluid or mucus buildup in the small airway passages of the lung causes localized patches of atelectasis (lung collapse). [1]
