Emphysema does not return to a normal state even in mild degrees. It is caused by a decrease in the elastic retraction force of the alveoli for various reasons, and the amount of residual gas inside the lungs increases. It is an irreversible chronic pathological change of the respiratory system due to excessive gas in the relative lungs that cannot be easily expelled. Through early and clear diagnosis and timely standardized treatment and care, such as the use of glucocorticoid budesonide, bronchodilators such as salbutamol, terbutaline, etc. The symptoms can be relieved by oral and nebulized inhalation administration. Prompt anti-inflammatory treatment such as cefoperazone sulbactam sodium and amoxicillin clavulanate potassium are used when accompanied by acute infection. During the course of the long remission period, continuous low-flow oxygen can be administered every day, and the usual breathing exercise training of abdominal breathing, lip contraction breathing and balloon blowing to enhance cardiopulmonary function can relieve and stop the progression of emphysema to a severe degree, prevent the appearance of pulmonary heart disease and improve the quality of life of patients.
