Chronic Obstructive Pulmonary Disease (COPD)

What is COPD?

Chronic obstructive pulmonary disease, or COPD, refers to a group of diseases that cause airflow blockage and breathing-related problems. The two most common conditions included within COPD are chronic bronchitis and emphysema: 

  • Chronic bronchitis is inflammation of the lining of the bronchial tubes, which carry air to and from the air sacs (alveoli) of the lungs. It's characterized by daily cough and mucus (sputum) production.
  • Emphysema is a condition in which the alveoli at the end of the smallest air passages (bronchioles) of the lungs are destroyed due to damaging exposure to cigarette smoke and other irritating gases and particulate matter.

 

Risk factors

  • Tobacco smoking
  • Pollution
  • Occupational dusts and chemicals (vapors, irritants, and fumes) 

 

Diagnosis
Tests include:
 
  • Lung pulmonary function tests – measure the amount of air you can inhale and exhale, and if the lungs are delivering enough oxygen to your blood
  • Spirometry – spirometer machine measures how much air your lungs can hold and how fast you can blow the air out of your lungs
  • Chest x-ray – can show emphysema and rule out other lung problems or heart failure
  • CT scan – detects emphysema and helps determine if one benefits from surgery for COPD
  • Arterial blood gas analysis – blood test that measures how well lungs are bringing oxygen into the body and removing carbon dioxide. 

 

Treatment
COPD is not curable. However, medical and physical treatments can help relieve symptoms, improve exercise capacity and quality of life and reduce the risk of death. 


 

# COPD BY THE NUMBERS #
  • Globally, it is estimated that about 3 million deaths were caused by the disease 
  • More than 13 million Americans suffer from COPD
  • More than 90% of COPD deaths occur in low and middle-income countries.
  • 20 to 30 percent of chronic smokers may develop clinically apparent COPD

People with COPD may be restricted by their disease in terms of achieving life goals, maintaining an active social life, or caring for their family.  In addition to severely impacting a person’s quality of life, loss of activity in patients can have a serious economic impact at a societal level.  Here are 8 ways in which COPD can impact individuals, families, and the country as a whole:
