Patients diagnosed with chronic obstructive pulmonary disease, or COPD, should quit anxiety, build confidence in controlling and overcoming the disease, and not close themselves at home, in addition to active standardized drug treatment. Avoid risk factors: quit smoking, keep indoor ventilation, and improve indoor and outdoor air pollution. Improving physical resistance: perform household activities and exercise as much as you can, step by step, to enhance physical fitness, improve resistance, try to avoid the occurrence of respiratory infections such as colds, and use vaccines. Influenza vaccination can reduce the disease and death rate. Pneumococcal polysaccharide vaccination of COPD patients aged ≥65 years or, although less than 65 years, with FEV1% below 40% of the expected value, may reduce the incidence of community-acquired pneumonia. It is recommended that the seasonal vaccine be administered at the local vaccination station during stable disease. Vaccination should not be administered during acute exacerbations. Adherence to respiratory exercises: You can gradually practice adapting to some specific breathing styles, including aerobic exercises such as slow walking, qigong, and taijiquan. Adhere to breathing exercises such as lip reduction breathing, which can help prevent airway trapping, reduce respiratory power consumption, improve ventilation efficiency, and help the discharge of phlegm and improve lung function. Enhance nutrition and improve the strength of respiratory muscle groups: Patients with COPD commonly suffer from malnutrition. At the same time, long-term chronic hypoxia and cardiac insufficiency lead to reduced digestive and absorption function of gastrointestinal tract, so patients should pay attention to daily diet rich in nutrients and light and easy to digest. Long-term home oxygen therapy: For very severe patients with combined hypoxemia, home oxygen therapy can be considered if available. Several studies at home and abroad have confirmed that long-term oxygen therapy can significantly extend the life span of patients and improve the quality of life.
