pulmonary emphysema
A doctor shows a patient a diagram of healthy lungs and lungs affected by pulmonary emphysema.
Noun: A chronic, progressive lung disease characterized by the abnormal, permanent enlargement of the air spaces (alveoli) at the end of the bronchial tubes, accompanied by the destruction of their walls. This damage reduces the lungs' elasticity and impairs the body's ability to expel air, leading to decreased respiratory function. It is strongly associated with long-term smoking, chronic bronchitis, and aging.
The term "pulmonary emphysema" is a medical noun used to name a specific disease state. It is typically used in clinical, diagnostic, and patient education contexts. - It is often discussed in relation to its causes, symptoms (like shortness of breath), and its frequent classification under the umbrella term Chronic Obstructive Pulmonary Disease (COPD).
- The patient's long history of smoking led to a diagnosis of pulmonary emphysema.
- Pulmonary emphysema and chronic bronchitis are the two main conditions that constitute COPD.
- The primary symptom of pulmonary emphysema is a progressive feeling of breathlessness during physical activity.
- Pathophysiology Context: In medical literature, "pulmonary emphysema" is described by the specific pattern of lung tissue destruction, such as (affecting the center of the lung lobules) or (affecting the entire lobule).
- Clinical Staging: The severity of pulmonary emphysema is often staged using metrics like the GOLD (Global Initiative for Chronic Obstructive Lung Disease) criteria, which assess the degree of airflow limitation.
- Emphysema: A common shortened form of "pulmonary emphysema." In a broad medical context, "emphysema" can sometimes refer to other conditions involving air in tissues (e.g., subcutaneous emphysema), but it is most frequently synonymous with the pulmonary form.
- COPD (Chronic Obstructive Pulmonary Disease): The overarching disease category that includes pulmonary emphysema and chronic bronchitis.
- Alveoli: The tiny air sacs in the lungs that are destroyed in pulmonary emphysema.
- Emphysema (when context clearly refers to the lungs)
- COPD (as a general category, though not perfectly synonymous as COPD includes other conditions)
- Alpha-1 Antitrypsin Deficiency: A genetic condition that can cause pulmonary emphysema, even in non-smokers.
- Air Trapping: A key physiological consequence of pulmonary emphysema where air becomes trapped in the damaged lungs during exhalation.
- Barrel Chest: A physical sign sometimes associated with advanced pulmonary emphysema, where the chest takes on a rounded, barrel-like appearance due to hyperinflation of the lungs.

- an abnormal condition of the lungs marked by decreased respiratory function; associated with smoking or chronic bronchitis or old age
