Productive cough be present on most days for a minimum of 3 months in the year in at least two consecutive years.
During relatively quiescent period, the only finding may be increased anteroposterior diameter of the chest. Other findings such as hyperresonance to percussion,prolonged expiratory phase, scattered diffuse coarse or moderate brhonchi and rales and wheezing are also present.
Chest x-ray shows evidence of pulmonary overinflation with increased anteroposterior diameter, flattened diaphragm and increased retrosternal air space. There are often prominent and increased bronchial markings at the lung base as
parallel or tapering shadows ("tram lines") which reflect the increased thickness of the bronchial wall.
Treatment
The patient should be vigorously encouraged to discontinue cigrette smoking and avoid exposure to other toxic inhalants and postural drainage exercises when possible. The preferred drug is Ampicillin or Erythromycin and Tab Amnophyllinefor five to seven days.
In traditional Chinese medicine, this disorder is divided into cold-phlegm and heat-phlegm types, the therapy of each varies. Cold-phlegm is characterized clinically by cough with copious and easily coughed up sputum and relief of cough after expectoration and accompanied by such symptoms as a feeling of suppression of the chest, poor appetite, white glossy coating of the tongue, superficial and slippery pulse, etc. But the heat type is due to the accumulation and retention of the phlegm and the pathogenic heat in the lungs with major symptoms such as cough, dyspnea,yellowish thin or bloody sputum, chest and hypochondriac pain, red tongue with yellowish glossy coating, smooth and rapid pulse.
