Obstruction of airflow that is chronic in nature

It occurs when the airways become narrow

Is often the result of chronic conditions such as chronic bronchitis or emphysema.

Cigarette smoking is one of the leading causes of COPD – other pollutants can also be associated such as dust, chemicals, and pollution.

As a result of such chemicals, changes in lung function can be seen in those with COPD.

Smoking alone accounts from 70-80% of COPD cases

Typically seen in someone older than 60

Symptoms include:

   -    Cough is the most consistent symptom
   -    Dyspnea (Shortness of breath)
   -    Sputum
   -    Difficulty breathing with or without exercise, among others
   -    Fatigue
   -    Wheezing
   -    Cyanosis
   -    Chest enlargement

Cor pulmonale may be a complication of late stage COPD

X-ray imagining can be somewhat helpful

COPD can have episodes of worsening and improving – during some worsening time other additional conditions can occur
   -    Acute Bronchitis
   -    Heart failure
   -    Pulmonary hypertension or high blood pressure
   -    Pneumonia
   -    Respiratory failure
   -    And others

Treatment :

Prevention is attained through no long-term smoking
·        Transdermal patch
·        Nicotine gum
·        Chantix
·        Bupropion

Oxygen is often essential in moderate to severe COPD

Bronchodilators
·        Ipratropium bromide
·        Albuterol
·        Metaproterenol

Oral Theophylline

Corticosteroids

Antibiotics
·        Trimethoprim-sulfamethoxazole
·        Amoxicillin
·        Amoxicillin-clavulanate
·        Doxycycline
 

Surgery may be appropriate in some cases
   -   Lung transplantation
   -   Volume capacity surgery – Lung reduction
