Clinical Information

  • EMPHYSEMA-. a pathological accumulation of air in tissues or organs.
  • MEDIASTINAL EMPHYSEMA-. presence of air in the mediastinal tissues due to leakage of air from the tracheobronchial tree usually as a result of trauma.
  • PNEUMONIA ATYPICAL INTERSTITIAL OF CATTLE-. a cattle disease of uncertain cause probably an allergic reaction.
  • PULMONARY EMPHYSEMA-. enlargement of air spaces distal to the terminal bronchioles where gas exchange normally takes place. this is usually due to destruction of the alveolar wall. pulmonary emphysema can be classified by the location and distribution of the lesions.
  • SUBCUTANEOUS EMPHYSEMA-. presence of air or gas in the subcutaneous tissues of the body.
  • EMPHYSEMATOUS CHOLECYSTITIS-. a variant of acute cholecystitis with inflammation of the gallbladder that is characterized by the pockets of gas in the gallbladder wall. it is due to secondary infection caused by gas forming organisms and has a high risk of perforation.

Information for Patients


Emphysema is a type of COPD involving damage to the air sacs (alveoli) in the lungs. As a result, your body does not get the oxygen it needs. Emphysema makes it hard to catch your breath. You may also have a chronic cough and have trouble breathing during exercise.

The most common cause is cigarette smoking. If you smoke, quitting can help prevent you from getting the disease. If you already have emphysema, not smoking might keep it from getting worse. Treatment is based on whether your symptoms are mild, moderate or severe. Treatments include inhalers, oxygen, medications and sometimes surgery to relieve symptoms and prevent complications.
