  2. Bronchoscopic lung volume reduction - Wikipedia

    en.wikipedia.org/wiki/Bronchoscopic_lung_volume...

    Bronchoscopic lung volume reduction (BLVR) is a procedure to reduce the volume of air within the lungs. BLVR was initially developed in the early 2000s [ 1 ] [ 2 ] as a minimally invasive treatment for severe COPD that is primarily caused by emphysema .

  3. Endobronchial valve - Wikipedia

    en.wikipedia.org/wiki/Endobronchial_valve

    This leaves the rest of the lung to expand more normally and avoid air-trapping. Endobronchial valves are typically implanted using a flexible delivery catheter advanced through a bronchoscope in minimally invasive bronchoscopic lung volume reduction procedures in the treatment of severe emphysema. The valves are also removable if they are not ...

  4. Collateral ventilation - Wikipedia

    en.wikipedia.org/wiki/Collateral_ventilation

    The presence of interlobar collateral ventilation will affect the choice of lung volume reduction procedure that may be offered in severe cases of emphysema. Emphysema usually develops in later years from the breakdown of alveolar walls resulting in much larger airspaces and much larger pathways for a preferential route of collateral ventilation.

  5. 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 ...

    A newer treatment for emphysema could save patients from major surgery. A Milwaukee pulmonologist is hoping to spread the word.

  7. FEV1/FVC ratio - Wikipedia

    en.wikipedia.org/wiki/FEV1/FVC_ratio

    In obstructive lung disease, the FEV1 is reduced due to an obstruction of air escaping from the lungs. Thus, the FEV1/FVC ratio will be reduced. [4] More specifically, according to the National Institute for Clinical Excellence, the diagnosis of COPD is made when the FEV 1 /FVC ratio is less than 0.7 or [8] the FEV 1 is less than 75% of predicted; [9] however, other authoritative bodies have ...
