  2. Emphysema - Wikipedia

    en.wikipedia.org/wiki/Emphysema

    Panlobular emphysema, also called panacinar emphysema, affects all of the alveoli in a lobule, and can involve the whole lung or mainly the lower lobes. [ 18 ] [ 24 ] This type of emphysema is associated with alpha-1 antitrypsin deficiency (A1AD or AATD), and Ritalin lung , [ 24 ] and is not related to smoking.

  3. Combined pulmonary fibrosis and emphysema - Wikipedia

    en.wikipedia.org/wiki/Combined_pulmonary...

    Combined pulmonary fibrosis and emphysema (CPFE), describes a medical syndrome involving both pulmonary fibrosis and emphysema. [ 1 ] [ 2 ] The combination is most commonly found in male smokers. Pulmonary function tests typically show preserved lung volume with very low transfer factor.

  4. Lung compliance - Wikipedia

    en.wikipedia.org/wiki/Lung_compliance

    In a highly compliant lung, as in emphysema, the elastic tissue is damaged by enzymes. These enzymes are secreted by leukocytes (white blood cells) in response to a variety of inhaled irritants, such as cigarette smoke. Patients with emphysema have a very high lung compliance due to the poor elastic recoil. They have extreme difficulty exhaling ...

    Emphysema is a chronic lung condition that causes shortness of breath. The disease is generally caused by cigarette smoking (the 78-year-old Lynch is a lifelong smoker) or exposure to pollutants.

  6. Obstructive lung disease - Wikipedia

    en.wikipedia.org/wiki/Obstructive_lung_disease

    This can be measured with breathing devices such as a peak flow meter or by spirometry. Most people with COPD have characteristics of emphysema and chronic bronchitis to varying degrees. Asthma being a reversible obstruction of airways is often considered separately, but many COPD patients also have some degree of reversibility in their airways ...

  7. Functional residual capacity - Wikipedia

    en.wikipedia.org/wiki/Functional_residual_capacity

    For instance, in emphysema, FRC is increased, because the lungs are more compliant and the equilibrium between the inward recoil of the lungs and outward recoil of the chest wall is disturbed. As such, patients with emphysema often have noticeably broader chests due to the relatively unopposed outward recoil of the chest wall.

  8. Pneumomediastinum - Wikipedia

    en.wikipedia.org/wiki/Pneumomediastinum

    The main symptom is usually severe central chest pain. Other symptoms include laboured breathing, voice distortion (as with helium) and subcutaneous emphysema, specifically affecting the face, neck, and chest. [4] Pneumomediastinum can also be characterized by the shortness of breath that is typical of a respiratory system problem.

  9. Airway resistance - Wikipedia

    en.wikipedia.org/wiki/Airway_resistance

    Airway resistance can also change over time. During an asthma attack the airways constrict causing an increase in airway resistance. Airway resistance can also vary between inspiration and expiration: In emphysema there is destruction of the elastic tissue of the lungs which help hold the small airways open. Therefore, during expiration ...
