It is also necessary for patients with chronic obstructive pulmonary disease to perform respiratory exercises, which can not only exercise respiratory muscles, improve patients’ fatigue, weakness and dyspnea, improve tolerance to physical activities, enhance physical fitness and enable them to establish effective respiratory form, but also prevent and reduce damage to lung function due to hypoxia and carbon dioxide retention, delay abnormal consumption and degeneration in patients with respiratory insufficiency, change patients The symptoms of weakness and dyspnea as well as the general condition of the body enable some patients with dyspnea and chronic respiratory failure to take care of their daily lives and improve the quality of survival of patients, and if the training modality is correctly selected and can be properly applied, it can shorten the course of the disease and promote the recovery of patients, so respiratory exercise is an important method for treating symptomatic chronic obstructive pulmonary disease. The simplest respiratory exercise is deep breathing, which can increase the ventilation area of alveoli, enhance the activity of lung muscles and improve respiratory function. Patients with chronic obstructive pulmonary disease can take deep breaths in the woods or parks with high oxygen content in the morning and evening. 30 is appropriate for the first time, and the amount can be increased gradually after adaptation. The abdominal breathing method is to enhance lung ventilation through diaphragmatic activity. Patients with chronic obstructive pulmonary disease place one hand on the upper abdomen, exhale as the hand sinks with the abdomen and exerts slight pressure, inhale as the upper abdomen resists this pressure, and the abdomen rises slowly. Three to five times a day for 3 minutes each time. Patients should also pay attention to relaxing the muscles of the whole body when performing abdominal breathing. When exhaling, the abdomen should be made to sink, and force should be avoided. When inhaling, the abdomen should be puffed out for slightly longer than the exhale. Do not exhale immediately after each inhalation, to pause for a moment. The flute exhalation method, also called lip constriction breathing, is effective in preventing premature occlusion of the bronchi due to inflammatory attack. The patient takes a breath in through the nose, and then narrows the lips into a flute shape so that the gas is exhaled slowly through the narrowed mouth shape, and then repeats it again. Do it 6 times and then pause for a while and repeat. It is advisable to use the nasal cavity when inhaling, and the air is filtered and moistened in the nasal cavity, which reduces the adverse irritation to the trachea.
