The most likely cause of this patients dyspnoea is chronic bronchitis due to his history of chronic smoking and the recent production of green phlegm with an increased mucus production
Therapy is generally focused on alleviation of symptoms.Toward this goal, a doctor may prescribe a combination of medications that open obstructed bronchial airways and thin obstructive mucus so that it can be coughed up more easily. Care for acute bronchitis is primarily supportive and should ensure that the patient is oxygenating adequately. Bed rest is recommended.
Acute treatment for the patient would be therapy with short-acting agonists or anticholinergic bronchodilators if there is acute exacerbation to help dilate the bronchioles and reduce inflammation. Additionally a short course of systemic corticosteroid therapy to aid with inflammation reduction and allow phlegm to be coughed up more easily
The most helpful intervention to help prevent future exacerbation is the avoidance of environmental irritants, especially cigarette smoke. and reducing the amount of smoking per day this will help control cough and sputum production in patients with chronic bronchitis
