Chronic obstructive pulmonary disease (COPD) is a chronic lung disorder. COPD includes two main illnesses: chronic bronchitis and emphysema.
- Moves into the trachea (the "trunk" of the upside-down tree)
- Flows into smaller tubes called bronchi and bronchioles (the "branches" of the tree)
- Makes its way into air sacs called alveoli (the "leaves" of the tree)
Oxygen from the air passes through the alveoli and into the bloodstream. At the same time, waste gas (carbon dioxide) is passed from the blood stream to the alveoli and exhaled.
Causes of COPD
Smoking is the leading cause of COPD. Other causes include: Breathing industrial wastes for a long of time and scarred or damaged lung tissue.
Signs of COPD
- Problems breathing
- Shortness of breath
- Wheezing
- Excess mucus
- Coughing
- Weakness and exhaustion
- Weight loss
As less oxygen gets into the bloodstream, the person's lips, nails, and skin may look blue. Heart failure (a condition that results when the heart cannot pump blood effectively can also develop.)
How is COPD treated?
- Stop smoking
- Medicine, including antibiotics and steroids
- Oxygen
- Surgery
