Disease |
Pathophysiology |
| Over-inflation of the alveoli due to the breakdown of the alveolar walls and decreasing the ability to exchange O2 & CO2 (a Ventilation/Perfusion mismatch). A loss of elasticity in the lung fibers creates difficulty in exhaling therefore trapping air in the damaged alveoli. This loss of elasticity is usually related to a chemical imbalance brought about by consistent inhalation of smoke, air pollution, and irritating fumes/dusts. This condition begins and worsens gradually. | |
| A chronic obstruction of the pulmonary system due to the combination of of two obstructive diseases, the most common being chronic bronchitis and emphysema. It is rare to have pure emphysema, while pure chronic bronchitis is common. This disease is slow to develop over many years of inhaled irritants. | |
| As a reaction to an inhaled substance, stress, or cold, the cells of the airways secrete more mucus than normal that is very thick and sticky; the airways swell and the bronchial muscles begin to constrict further narrowing the airways. This can occur suddenly or gradually over a period of days. | |
| As a reaction to the chronic inhalation of smoke or industrial dust, this disease is a chronic inflammation of the lining of the bronchial tree resulting in the consistent over-production of mucus hampering air flow to the alveoli. The excessive mucus irritates the bronchial tree causing an chronic productive cough. It is generally worse in the morning and on cold, damp days. |
