Emphysema occurs mostly in the elderly, and patients with long-term lung diseases such as chronic bronchitis or asthma are prone to develop emphysema. Emphysema can cause whistling whistling difficulty, air is easy to enter but not easy to exit, impeding gas exchange and increasing resistance to pulmonary circulation, thus it can develop into pulmonary heart disease and finally heart failure, whistling failure and pulmonary brain syndrome. Patients with emphysema in the elderly should do a good job of daily maintenance to slow down the progress of the disease. Emphysema maintenance in the elderly should do the following:. 1, elderly patients with emphysema diet should pay attention to the nutritional composition, more protein-based food supplements. Those who have heart failure should pay attention to avoid salt. If the amount of long-term diet is low, and those who use diuretics should pay attention to the supplementation of potassium ions. Food with orange, banana, fresh mushroom and other potassium ion content is high. 2.The maintenance of emphysema in the elderly should make a record of the amount of food, water and urine and stool discharged every day. 3, emphysema in the elderly should quit smoking, daily maintenance attention to avoid smoke and harmful gas inhalation. 4, the recovery period of chronic whistle failure patients, can be abdominal whistle. As the patient’s ability to use the thoracic whistle muscle for gas exchange has reached its limit, the abdominal diaphragm must be fully mobilized to assist the whistle function, to improve the amount of oxygen and effective ventilation, in order to make up for the lack of ventilation and reduce symptoms. 5, with taijiquan, qigong, long-distance walking and other physical therapy. 6, such as elderly patients with emphysema suddenly occur in severe acute whistling, heart failure and gastrointestinal bleeding symptoms, should be immediately sent to the hospital for treatment.
