Exercise training is the cornerstone of comprehensive pulmonary rehabilitation for COPD patients. Exercise training is the cornerstone of comprehensive pulmonary rehabilitation, including lower extremity exercise training and upper extremity exercise training, which in turn is a key core component of pulmonary rehabilitation. Therefore, a customized exercise prescription for the patient is essential. The concept of exercise prescription is that the rehabilitation physician or physical therapist prescribes the type of exercise, exercise intensity, exercise time, exercise frequency, and exercise cycle, as well as the precautions to be taken during the exercise, based on the medical examination (including exercise tests and physical tests), according to the health, physical strength, and cardiovascular function status of the patient. The procedure for developing an exercise prescription is to collect personal medical history and information, conduct a comprehensive physical examination, obtain auxiliary information such as static pulmonary function tests, electrocardiograms, chest X-rays or CT, conduct exercise load tests, develop an individual exercise rehabilitation prescription, evaluate the patient every 3-6 months, and adjust the exercise prescription as needed. Pulmonary Rehabilitation Q&A Q: What benefits does pulmonary rehabilitation provide to patients? A: With comprehensive pulmonary rehabilitation measures, patients can experience significant improvement in symptoms, increased respiratory endurance and efficiency, increased self-confidence and self-care, improved health-related quality of life (HRQL), reduced acute exacerbation rates, hospitalization days and hospitalizations, and improved psychological impairment and social adjustment without psychological intervention. 2006, the American Thoracic Society (ATS) recommended Pulmonary rehabilitation be incorporated into the treatment of stable COPD. Q: Is pulmonary rehabilitation only appropriate for patients with chronic and stable disease? A: No. Acute exacerbations are an important cause of lung function and quality of life decline and even death in COPD patients. Without pulmonary rehabilitation, lung function and quality of life can deteriorate further in patients with acute exacerbations of COPD (AECOPD), even with optimal drug therapy. There is no clear consensus on when to start pulmonary rehabilitation in these patients, but empirically, early pulmonary rehabilitation can be started once their infection is controlled. Q: How should patients cooperate with their doctors during pulmonary rehabilitation? A: First, the patient should be aware of the disease and its resulting symptoms and functional impairment, have the desire and confidence to actively participate in rehabilitation, and have no other obstructive or unstable conditions; second, the ideal group of people to participate in pulmonary rehabilitation is those who are still able to walk longer distances, but have noticed a yearly decline in exercise tolerance, or have recently developed pulmonary symptoms and complications, and have a strong desire to participate in rehabilitation, and should not be rigidly prescribed pulmonary function index or age as criteria for participation in rehabilitation; again, patients should also complete home rehabilitation training according to the rehabilitation prescription formulated by their physicians and should enhance nutrition. Q: Does the patient’s medication need to be changed during pulmonary rehabilitation? A: Pulmonary rehabilitation is a continuation of the original treatment, and the patient’s medication does not need to be changed. Exercise training has a synergistic effect with the medications commonly used for COPD patients, which can make pulmonary rehabilitation more effective.
