Winter is the high incidence of slow obstructive pulmonary disease, slow obstructive pulmonary disease patients should pay special attention to maintenance in winter, many patients will actively pay attention to the exercise of the lungs, but many people will ignore the exercise of respiratory muscles, but experts remind slow obstructive pulmonary disease patients of the respiratory muscle exercise is very important. Respiratory muscles are the only skeletal muscles on which life depends, and they are the driving force to complete the external respiratory function. Studies have shown that breathing difficulties in patients with chronic obstructive pulmonary disease (COPD) are closely related to the reduced function of respiratory muscles. Because the respiratory muscles of patients with chronic obstructive pulmonary disease are overloaded for a long time, they cannot produce and maintain a certain muscle force, which will produce muscle contraction weakness, called respiratory muscle fatigue, which will lead to reduced alveolar ventilation and serious respiratory failure, so patients with chronic obstructive pulmonary disease should actively prevent the problem of respiratory muscle fatigue. The respiratory muscle fatigue and respiratory muscle failure will be prevented by timely respiratory muscle exercise, which will ensure that the respiratory muscle maintains a certain intensity of muscle strength and endurance, so as to ensure that patients with chronic obstructive pulmonary disease have sufficient power to breathe. The method of daily exercise respiratory muscle for patients with chronic obstructive pulmonary disease: 1, patients with chronic obstructive pulmonary disease can do some slow exercise in appropriate amounts, such as jogging, yoga, Tai Chi, etc.. 2, can also be conscious of abdominal breathing, lip reduction breathing, which is not only conducive to the exercise of respiratory muscle, will also have a very good auxiliary treatment effect on the slow lung obstruction. You can also consciously blow up more balloons and candles.
