Chronic obstructive pulmonary disease (COPD) is a common and frequent disease, and when it develops into obstructive emphysema, the disease enters into an irreversible stage with progressive aggravation. Treatment should be strengthened during the stabilization period to reduce the number of acute exacerbations. Exercise training: Increase the amount of exercise gradually. At the beginning, each exercise time 5 minutes, gradually increase, maintain at 20-30 minutes. The principle is not to produce fatigue and uncomfortable reaction. 2. Breathing Exercise 2.1 Abdominal Breathing Exercise Use one hand to press on the upper abdomen, and when you exhale, the abdomen sinks, and the hand presses slightly to further increase the intra-abdominal pressure and force the diaphragm to lift up. Inhalation, the upper abdomen against the pressure of the hand, the abdomen slowly rise, every 5 minutes once repeated. The same training is performed in the upright and prone positions. 2.2 Exhale with contracted lips Inhale calmly through the nose while silently counting 1-2, tighten the lips in a whistle-like manner while breathing, relax and exhale while silently counting 1-2-3-4. Keep inhale/exhale = 1:2 for one respiratory cycle, and practice at least 5 minutes in each of the three positions of recumbent, seated, and upright every day, and gradually practice as much as possible. This method can increase endobronchial pressure, avoid premature occlusion of bronchial tubes, and reduce PaCO2. Chest physiotherapy Chest patting or vibration by hand or with instruments can help discharge secretions that are difficult to cluck out. 4, home oxygen therapy Long-term home oxygen therapy indications: PaO2 ≤ 55mmHg or SaO2 ≤ 88%; PaO255 ~ 70mmHg and pulmonary hypertension, right heart failure or erythrocytosis; Oxygen therapy time: daily low-flow oxygen inhalation for at least 15 hours; Oxygen therapy goals: so that the PaO2 of at least 60mmHg. Benefits of Oxygen Therapy: Continuous home oxygen therapy prolongs the life span of hypoxemic COPD patients, which correlates with the length of daily oxygen intake. Long-term oxygen therapy can also reduce pulmonary artery pressure and improve dyspnea. 5.Nutritional support High protein, high fat, low carbohydrate is suitable for patients with ventilation dysfunction.
