Bronchitis:  inflammation of one or more

Bronchus:  one of the larger passages conveying air
to and within the lungs

Chronic Bronchitis:  Excessive mucus production with productive
cough for at least 3 months a year for 2 successive years.  Only a
minority of patients with the clinical syndrome of chronic bronchitis develop
significant airway obstruction.

Cause:  Severitly of disease related to amount and duration
of smoking; respiratory infection  exacerbates symptoms;  Allergies;

Hypertrophy ( enlargement or overgrowth) and hyperplasia ( abnormal
increase in the number of normal cells in normal arrangement )of bronchial
mucous glands

Wide spread inflammation


Narrowing of airways, and mucus within the airways produce resistance
in small airways and cause severe ventilation perfusion imbalance




Shortness of breath

Dyspnea (difficulty breathing)

Chronic Bronchitis:

Insidious onset, with productive  cough and exertional dyspnea

Colds associated with increased sputum production and worsening dyspnea
that take progressively longer to resolve; copious sputum (gray, white,
or yellow in color)

Weight gain from edema ( abnormal accumulation of fluid in intercellular
spaces of the body)

Cyanosis (a bluish discoloration of skin)

Tachypnea (rapid respiration)


Prolong expiratory time

Use of accessory muscles of respiration


Antibiotic therapy – for infections

Bronchodilators – to relieve bronchospasm and facilitate mucocillary

Adequate fluid intake and chest physiotherapy to mobilize secretions

Ultrasonic or mechanical nebulizer treatments to loosen secretions and
aid in mobilization

Occasionally Corticosteroids

Diuretics for edema

Oxygen for hypoxemia (deficient oxygenation of the blood)

Avoidance of smoking and air pollutants
