COPD is a chronic lung disease characterized by obstructed airflow from the lungs caused by chronic inflammation and tissue destruction in the lungs. Over time, inflammation causes excessive mucus production and the enlargement of air spaces in the lungs, resulting in long-term obstruction of airflow. Treatments for severe COPD include procedures to remove damaged areas of the lungs, such as bullae or large air sacs, as well as lung volume reduction surgery or transplantation to improve breathing.

- 2. DEFINITION Chronic obstructive pulmonary disease (COPD) is a chronic inflammatory lung disease that causes obstructed airflow from the lungs. Symptoms include breathing difficulty, cough, mucus (sputum) production and wheezing.

- 11. Bullectomy is a procedure where doctors remove one or more of the very large bullae or blebs from the lungs. Bullae are large air sacs that form from hundreds of destroyed alveoli. These air spaces can become so large that they crowd out the better functioning lung and interfere with breathing. For those people, removing the destroyed air sacs improves breathing. Lung Volume Reduction Surgery (LVRS) is a procedure to help people with severe emphysema affecting the upper lung lobes Lung transplantation
