(1) Pay attention to aftercare at ordinary times, improve physical health and resistance, which is the basis for improving lung function, and establish confidence in healing. This disease is not incurable. (2) According to patients' physical strength, they can actively participate in some appropriate sports activities. For example, jogging is the most complete coordinated exercise of the whole body, which can increase vital capacity and endurance. When jogging, keep breathing evenly and let enough oxygen enter the body. Tai Ji Chuan, soft exercises, walking and so on can improve your health. Patients who keep exercising for many years can keep healthy better than those who rest more and exercise less. (3) Patients with emphysema are most afraid of cold in winter, and they are also prone to catch a cold. After each respiratory infection, their symptoms will get worse and their lung function will be affected. Cold-resistant exercise can improve their resistance. Since beginning of spring, I have rubbed my head, face and exposed parts of upper and lower limbs with my hands for several times every day for a few minutes until my skin turns red. Soak the towel in cold water in summer and wring it out, then rub it all over your body, 1-2 times a day. Wipe your face with cold water after autumn. In this way, after cold-resistant exercise, you can reduce colds and respiratory infections. (4) When emphysema patients have lung infection, they must stay in bed, actively resist inflammation, relieve spasm and asthma, and take medicine on time. Don't rush to make up for it, in principle, it is still based on eliminating evil. After infection control, it can be gradually adjusted. If you are usually tired and weak, you can easily catch a cold. You can choose Astragalus, Ginseng, Saposhnikovia divaricata, Atractylodes macrocephala, etc. (5) Pay attention to nutrition and improve the body's resistance. Choose foods with high protein content and rich vitamins, such as dairy products, eggs and gravy. Usually, the diet should be light, not too salty, and should be quantified regularly. Eat more fruits and vegetables and less seafood, such as shrimp, yellow croaker and hairtail. Stop drinking and smoking.
