➢Emphysema
– Chronic cough – Shortness of breath – Limited activity level
Normal versus Diseased Bronchi
Emphysema
How common is COPD?
➢ About 13.9% of the U.S. adult population (25+ years) have been diagnosed with COPD*
Studies show:
➢ An increased number of cases of chronic bronchitis in coal & gold miners
➢ Long-term exposures to low levels of silica may lead to the development of chronic bronchitis & emphysema
➢What increases my risk of developing COPD? ➢How can I prevent getting COPD? ➢How is COPD treated?
What is COPD?
➢A set of lung diseases that limit air flow and is not fully reversible.
– Slow progress of the disease – Relieve symptoms – Improve an individual’s ability to stay active – Prevent and treat complications – Improve quality of life

Overview
➢What is COPD? ➢How do I know if I have COPD? ➢How common is it?
– General population – Mining population
– An estimated 15-19% of COPD cases are workrelated**
➢ 24 million other adults have evidence of troubled breathing, indicating COPD is under diagnosed by up to 60%***
– Smoking cessation is critical for all severities of COPD
➢ Avoid or protect yourself from exposures to – Second-hand smoke and – Other substances such as chemical vapors, fumes, mists, dusts, and diesel exhaust fumes that irritate your lungs
COPD Death Rates in Mining Industry 1999
➢ Coal mining was at the top of a list of industries with a significantly elevated death rate from COPD
➢ Non-metal and metal mines were also in the top 5 industries for elevated COPD death rate
How is COPD Treated?
➢ COPD can be managed, but not cured
➢ Treatment is different for each individual and is based on severity of the symptoms
➢ Early diagnosis and treatment can
➢ Top 5 occupations for elevated COPD death rate included:
– Helpers, mechanics and repairers – Mining machine operators
What can cause COPD?
➢Smoking is the primary risk factor

– COPD patients report they are “hungry” for air – Usually progressive and is associated with
inflammation of the lungs as they respond to noxious particles or gases – Potentially preventable with proper precautions and avoidance of precipitating factors – Symptomatic treatment is available
What medications are used to treat symptoms?
➢Bronchodilators –
• Relaxes muscles around airways
➢Steroids
• Reduces inflammation
➢Oxygen therapy
• Helps with shortness of breath
– Long-term smoking is responsible for 80-90 % of cases
• Smoker, compared to non-smoker, is 10 times more likely to die of COPD
➢Prolonged exposures to harmful particles and gases from:
Centers for Disease Control, DHHS, CDC Programs in Brief-Workplace Health and Safety-Work-Related Lung Disease, 2005 /programs/workpl18.htm
When should you see your doctor?
➢ If smoker, see doctor for baseline evaluation of your lungs
➢ When first experiencing shortness of breath or having other lung symptoms
What medications are used to prevent complications?
➢Annual flu vaccine
– Reduces risk of flu and its complications
➢Pneumonia vaccine
– Reduces risk of common cause of pneumonia
➢ When your symptoms get worse
➢ Seek emergency medical treatment if:
– Breathing suddenly becomes more difficult
➢ If diagnosed with chronic bronchitis, emphysema or COPD, see doctor 1-2 times yearly to review your treatment plan
– Second-hand smoke, – Industrial smoke, – Chemical gases, vapors, mists & f; other materials
Other Risk Factors for COPD
Two Major Causes of COPD
➢Chronic Bronchitis is characterized by
– Chronic inflammation and excess mucus production
– Presence of chronic productive cough
➢History of childhood respiratory infections
➢Genetic makeup ➢Increasing age
Ways to prevent or slow the progression of COPD
➢ Stop smoking, if you smoke, to prevent further damage to your body
➢ Chronic exposure to coal dust, particularly high levels, may lead to severe respiratory impairment (emphysema)
*Hnizdo & Vallyathan Chronic obstructive pulmonary disease due to occupational exposure to silica dust: a review of epidemiological and pathological evidence. Occup Environ Med 2003;60:237-243.
➢Emphysema is characterized by
– Damage to the small, sac-like units of the lung that deliver oxygen into the lung and remove the carbon dioxide
– Chronic cough
COPD-A Major Cause of Hospitalization & Death
COPD was the: ➢Leading cause of hospitalizations in the U.S.
in 2000 ➢Fourth leading cause of death
COPD in the Mining Industry

Primary Symptoms
➢Chronic Bronchitis
– Chronic cough – Shortness of breath – Increased mucus – Frequent clearing of throat
– Chronic cough – Shortness of breath – Limited activity level
