  • Title: Chronic Obstructive Pulmonary Disease: Diagnosis and Management.
    Author: Gentry S, Gentry B.
    Journal: Am Fam Physician; 2017 Apr 01; 95(7):433-441. PubMed ID: 28409593.
    Abstract:
    The diagnosis of chronic obstructive pulmonary disease (COPD) should be suspected in patients with risk factors (primarily a history of smoking) who report dyspnea at rest or with exertion, chronic cough with or without sputum production, or a history of wheezing. COPD may be suspected based on findings from the history and physical examination, but must be confirmed by spirometry to detect airflow obstruction. Findings that are most helpful to rule in COPD include a smoking history of more than 40 pack-years, a self-reported history of COPD, maximal laryngeal height, and age older than 45 years. The combination of three clinical variables-peak flow rate less than 350 L per minute, diminished breath sounds, and a smoking history of 30 pack-years or more-is another good clinical predictor, whereas the absence of all three of these signs essentially rules out airflow obstruction. Pharmacotherapy and smoking cessation are the mainstays of treatment, and pulmonary rehabilitation, long-term oxygen therapy, and surgery may be considered in select patients. Current guidelines recommend starting monotherapy with an inhaled bronchodilator, stepping up to combination therapy as needed, and/or adding inhaled corticosteroids as symptom severity and airflow obstruction progress.
