Source: Up To Date : — Chronic obstructive pulmonary disease (COPD) is a common respiratory condition characterized by airflow limitation. It affects more than 5 percent of the population and is associated with high morbidity and mortality. It is the third-ranked cause of death in the United States, killing more than 120,000 individuals each year. As a consequence of its high prevalence and chronicity, COPD causes high resource utilization with frequent clinician office visits, frequent hospitalizations due to acute exacerbations, and the need for chronic therapy (eg, supplemental oxygen therapy, medication). Establishing a correct diagnosis of COPD is important because appropriate management can decrease symptoms (especially dyspnea), reduce the frequency and severity of exacerbations, improve health status, improve exercise capacity, and prolong survival. As current and former smokers are also at risk for a number of other medical problems for which treatment is very different, respiratory symptoms should not be attributed to COPD without appropriate evaluation and diagnosis. #copd#pulmonary#lung#breathing#breath#live#life#medschool#medschoolradio#usmle#respiratorytherapy#respiration#elderlycare#elderly#smoking#disease#pathology
