What should I do if I have chronic obstructive pulmonary disease (COPD)? If recurrent airway infections are not well controlled and cause a decline in airway or overall respiratory function, then an assessment of lung function can determine that chronic obstructive pulmonary disease, or emphysema, is present. What should I do at this time? In fact, there is no need to be overly nervous, because emphysema should be effectively controlled with modern medical solutions, for example, we should do the following: 1. We must avoid repeated acute infections of the airway, such as colds and similar situations, and must take active precautions. Usually, we should do a good job of moisturizing and keeping the airway warm, stay away from the contaminated environment of the airway, stay away from infected people, and stay away from the contaminated environment. In high-risk seasons, such as autumn and winter, you can actively and effectively vaccinate against pneumonia to reduce the occurrence of acute airway infections.2. Actively perform chronic oxygen therapy, such as oxygen inhalation when resting at home, do airway humidification, and pay attention to the moisturization of the air at home. At the same time, daily carry out can carry out chronic aerobic training, such as shrink mouth deep breathing, swimming, tai chi, etc., conscious of regular and quantitative recovery. This can further consolidate the function of the lungs and even carry out rehabilitation. The basic drugs should be used consistently and regularly, especially the inhaled drugs should not be stopped. 3. Conduct regular monitoring and evaluation. If we can do the above four points well, COPD will not have much impact on our quality of life.
