Chronic Obstructive Pulmonary Disease (COPD) is a common preventable and treatable disease characterized by persistent airflow limitation. Airflow limitation develops progressively and is accompanied by an increased chronic inflammatory response of the airways and lungs to harmful particles or gases. Acute exacerbations and comorbidities influence the severity of the patient’s overall disease. Clinical manifestations include cough, sputum, and dyspnea, which are common in adults over 40 years of age, and the overall prevalence of COPD in China is 8.2%. COPD is the leading cause of death and disability globally, ranking as the 4th leading cause of death globally, with 2.75 million deaths annually. In economically developed regions, COPD has the fastest growing incidence of a disease that causes death. By 2020, it will be second only to cardiovascular disease in terms of global mortality. However, COPD has not attracted much attention. Last year’s “COPD Classroom” activity was attended by more than 1,000 patients and their families, and the survey found that: 1. 69% of patients with COPD have been underdiagnosed or misdiagnosed, because the early symptoms of COPD are not specific, and many people will go to the doctor only when they have shortness of breath and wheezing symptoms. By the time a definitive diagnosis is made, lung function is usually already moderately or severely impaired. This is one of the reasons for the low cure rate and high mortality rate of chronic obstructive pulmonary disease. Correct diagnosis of chronic obstructive pulmonary disease (COPD) requires pulmonary function tests, but only 6.5% of the respondents had previously undergone pulmonary function tests, and most COPD patients failed to receive timely diagnosis and treatment. Therefore, in order to raise awareness of COPD and its proper prevention and treatment, and to improve patients’ quality of life, the Department of Respiratory Medicine of the Affiliated Hospital of the Armed Police Medical College will continue to conduct COPD rehabilitation classes. Second, 80% of patients with COPD do not adhere to standardized treatment, especially during the remission period in spring and summer. COPD is prone to acute exacerbation in winter, while summer is the best time for patients to recover nutrition and exercise. In this class, respiratory specialists will be invited to explain the treatment and rehabilitation methods of COPD, and at the same time, answer patients’ questions about this disease and provide guidance on rehabilitation and diet. C. The six sessions of COPD Rehabilitation Classes in 2011 have benefited many COPD patients, many of whom have not been hospitalized due to acute exacerbation of COPD during the season of high incidence of acute exacerbation of COPD last year by means of standardized treatment and active self-exercise such as breathing exercises, which has not only alleviated the pain of the patients, but also reduced the expenditure of medical resources.
