COPD one of the most common lung disorders

Chronic obstructive pulmonary disease (COPD) is one of the most common lung disorders in adults and includes chronic bronchitis and emphysema. In COPD, the airway passages (known as bronchi and bronchioles) become obstructed because of inflammation and excess sputum (phlegm) production. With emphysema, the alveoli (tiny air sacs of the lung where oxygen is absorbed and carbon dioxide is released) are partially destroyed. These problems result in difficulty breathing and decreased amounts of oxygen delivered to the body’s tissues. COPD affects between 12 million and 24 million persons and is a leading cause of death in the United States. COPD affects both men and women, and the most common cause is smoking (accounting for 80%-90% of cases).


  • Shortness of breath
  • Cough
  • Sputum (phlegm) production
  • Wheezing
  • Decreased blood oxygen levels and increased carbon dioxide levels
  • Exercise intolerance

COPD may be mild and unrecognized for several years until symptoms worsen. Your doctor may measure breathing volumes, a test called spirometry. Sometimes a bronchodilator (inhaled medication to widen the airways) is given during this test. The oxygen level can be measured indirectly using pulse oximetry, which measures the oxygen saturation of hemoglobin through the surface of the skin or fingernail, or directly by a sample of blood from the artery. A chest x-ray can help determine the amount of lung damage and can also indicate pneumonia or other lung diseases.


  • Stop smoking! This is the most important step in treating any lung disease, including COPD.
  • Medications may include bronchodilators (to widen the air passages), steroids (to reduce inflammation), and antibiotics (to treat infection if it is present). Often, many medications are used in combination.
  • Some persons need oxygen at night, with activity, or all the time.
  • Pulmonary rehabilitation, including exercise, may help improve functional status (the ability to do daily activities).
  • Vaccines can help prevent or minimize other diseases, such as influenza or pneumococcal disease.
