Chronic obstructive pulmonary emphysema is a chronic disease with a long course that seriously affects health and labor force. Symptoms of chronic obstructive pulmonary emphysema: 1. Chronic cough. It is usually the first symptom. The cough is intermittent at first, heavier in the morning, and later in the morning and evening or throughout the day. 2. Coughing sputum. The cough is usually followed by a small amount of mucus sputum, which increases when combined with infection and may have purulent sputum. 3.Shortness of breath or difficulty in breathing. This is the hallmark symptom of chronic obstructive pulmonary disease, which appears only when exerting oneself in the early stage, and then gradually worsens to the extent that shortness of breath is felt even during daily activities and even at rest. 4.Shortness of breath and chest tightness. The tightness in the chest usually occurs after exertion. 5. Systemic symptoms. Such as weight loss, loss of appetite, peripheral muscle atrophy, etc. Chronic obstructive pulmonary emphysema diagnosis: pulmonary function measurement is a gold standard for the diagnosis of metastatic slow-onset lung. The main measurement is the one-second ventilation rate, which is to take a deep breath and then blow out the gas at the maximum speed to see how much of the total exhalation volume is exhaled in the first second. In patients with chronic obstructive pulmonary disease, the one-second ventilation rate is less than 70%. Treatment of emphysema: 1. Appropriate application of bronchodilator drugs; 2. Application of effective antibiotics according to the pathogenic bacteria or experience; 3. Respiratory function exercise as abdominal breathing, lip reduction and deep slow exhalation to strengthen the activity of respiratory muscles. Increase the activity of the diaphragm; 4, home oxygen therapy, 8-15 hours a day of oxygen can extend life; 5, physical therapy, such as qigong, taijiquan, breathing exercises, quantitative walking or ladder exercises; 6, prevention: first of all, quit smoking, pay attention to warmth, avoid cold, prevent colds and flu to improve environmental health, eliminate and avoid the impact of smoke, dust and irritant gases on the respiratory tract.
