  1. COPD Chronic obstructive pulmonary disease Juliana Tambellini University of Pittsburgh

  2. COPD • Chronic Obstructive Pulmonary Disease • Aprogressive disease that affects the lungs, making it difficult to breathe

  3. COPD: an umbrella term • Umbrella term used to describe progressive lung diseases which include: • Emphysema • Chronic bronchitis • Refractory (irreversible) asthma • Severe bronchiectasis

  4. Other names for COPD • Chronic Obstructive Lung Disease (COLD) • Chronic Lower Respiratory Disease (CLRD)

  5. COPD • Chronic obstructive pulmonary disease (COPD) is a lung ailment that is characterized by a persistent blockage of airflow from the lungs. • It is an under-diagnosed, life-threatening lung disease that interferes with normal breathing and is not fully reversible.

  9. Causes • Most cases of COPD occur as a result of long-term exposure to lung irritants that damage the lungs and the airways •  The most common irritant that causes COPD is cigarette smoke • In rare cases, a genetic condition called alpha-1 antitrypsin deficiency may play a role in causing COPD

  10. Who is at risk? • People who smoke or are exposed to smoke • People who have a family history of COPD are more likely to develop the disease if they smoke • Long-term exposure to other lung irritants also is a risk factor for COPD • Almost 90% of COPD deaths occur in low- and middle-income countries, where effective strategies for prevention and control are not always implemented or accessible.

  11. Symptoms • breathlessness • abnormal sputum (a mix of saliva and mucus in the airway) • a chronic cough • daily activities can become very difficult as the condition gradually worsens

  12. diagnosis • A simple diagnostic test called "spirometry“ measures how much air a person can inhale and exhale, and how fast air can move into and out of the lungs • Spirometry can detect COPD long before its Symptoms appear. 

  13. Treatment • COPD has no cure • Quitting smoking is the most important step an individual can take to treat COPD • Other treatments for COPD may include medicines, vaccines, pulmonary rehabilitation (rehab), oxygen therapy, and surgery

  14. Managing copd • COPD symptoms usually slowly worsen over time • A cold, the flu, or a lung infection may cause symptoms to intensify • Prescription antibiotics may treat infections and other medicines, such as bronchodilators and inhaled steroids, can help facilitate breathing

  15. Managing COPD • Avoid lung irritants • Get ongoing care • Manage the disease and its symptoms • Prepare for emergencies

  16. Copd: statistics • The National Heart, Lung, and Blood Institute (NHLBI) estimates that 12 million adults have COPD, and another 12 million are undiagnosed or developing COPD • Estimated that over 210 million people worldwide have COPD

  17. Copd: statistics • COPD cost the U.S. economy about $32.1 billion, in direct and indirect costs in 2002 • A person with COPD dies every four minutes in the U.S • COPD will be the third leading cause of death in the U.S. by 2020

  18. Who response • Raise awareness about the global epidemic of chronic diseases • Create more healthy environments, especially for poor and disadvantaged populations • Decrease common chronic disease risk factors, such as tobacco use, unhealthy diet and physical inactivity • Prevent premature deaths and avoidable disabilities from major chronic diseases
