COPD
• Chronic Obstructive Pulmonary Disease
• A progressive disease that affects the
lungs, making it difficult to breathe
COPD: AN UMBRELLA TERM
• Umbrella term used to describe progressive
lung diseases which include:
•
•
•
•
Emphysema
Chronic bronchitis
Refractory (irreversible) asthma
Severe bronchiectasis
OTHER NAMES FOR COPD
• Chronic Obstructive Lung Disease
(COLD)
• Chronic Lower Respiratory Disease
(CLRD)
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.
UNDERSTANDING COPD
• Critical to first understand normal lung function

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
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 middleincome countries, where effective strategies for
prevention and control are not always implemented or
accessible.
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
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.
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
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
MANAGING COPD
• Avoid lung irritants
• Get ongoing care
• Manage the disease and its symptoms
• Prepare for emergencies
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
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
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
