Chronic obstructive pulmonary disease. Reversing airflow obstruction from chronic bronchitis and emphysema
Abstract:
Chronic obstructive pulmonary disease (COPD) describes a group of disorders that cause obstruction to expiratory airflow. COPD should be suspected in a patient who has cough, sputum production, wheezing, and/or inappropriate dyspnea on exertion in the setting of prolonged exposure to cigarette smoke. With smoking cessation, avoidance of occupational and other bronchial irritants, and use of bronchodilators, antibiotics, and long-term oxygen when appropriate, the patient can minimize limitations on activity and complications.

Chronic Obstructive Pulmonary Disease
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...
