In December, winter is on the right track. With the coming of cold air across the country, respiratory diseases have entered a high incidence season, especially for patients with chronic obstructive pulmonary disease (COPD), because COPD is more prone to acute exacerbation or repeated attacks in winter.

　　The three 'signals' of acute COPD attack are cough, phlegm and asthma. If the patient's cough becomes worse, the amount of sputum increases, the color of sputum turns yellow, and it is purulent or mucous. When the symptoms of shortness of breath become worse, it often indicates that the patient's condition suddenly changes from a stable period to an acute aggravating period. However, the respiratory symptoms of some elderly patients are not obvious, only manifested as decreased appetite, edema and aggravation of lower limbs.

　　Mechanism of acute exacerbation of COPD

　　Chronic obstructive pulmonary disease (COPD) is characterized by chronic respiratory symptoms, gradual decline of pulmonary function and repeated acute exacerbations. The main pathogenesis is the impairment of epithelial barrier function, the activation of neutrophil/macrophage mediated intrinsic inflammatory response, the activation of secondary inflammatory response mediated by T cells/B lymphocytes, and the release of a variety of inflammatory mediators from a variety of inflammatory cells and structural cells, leading to the pathological changes of COPD.

　　Chronic obstructive pulmonary disease (COPD) is an irreversible respiratory disease. The early symptoms are not obvious, but when the examination is performed after obvious symptoms, the pulmonary function has decreased by 40% - 50%. Each acute exacerbation will cause irreversible damage to the patient's pulmonary function. Chronic obstructive pulmonary disease (COPD) not only damages the airways, alveoli and pulmonary vessels, but also damages extrapulmonary tissues, such as bones, skeletal muscles, heart and other organs. Although irreversible, experts said that COPD is still a disease that can be prevented and treated, and we must pay attention to prevention and continuous treatment.

　　How to prevent acute exacerbation of COPD in winter?

　　1、Quit smoking

　　Smoking will lead to many pathophysiological changes such as airway mucosal ciliary dysfunction, airway structural change, airway inflammation, airway obstruction, etc. Therefore, smoking cessation is the 'first prescription' for treating COPD.

　　2、Standardized treatment

　　Patients with chronic obstructive pulmonary disease (COPD) should continue to take stable drug maintenance treatment to improve lung function and quality of life. Actively prevent infection, and go to the hospital as soon as possible if there are signs of worsening symptoms.

　　3、guard against the flu

　　Cold seems to be a trivial matter, but for patients with chronic obstructive pulmonary disease (COPD), special care should be taken to avoid aggravating the course of COPD.

　　4、Breathing exercise

　　After the age of 25, the lung function is declining every minute. You can try to do breathing exercises and shrink your lips to increase the respiratory strength and slow down the decline of lung function.

　　5、Salt therapy

　　Salt aerosol therapy is a kind of non drug therapy originated from nature, which can be used as an auxiliary treatment for COPD in the rehabilitation period. At this year's incubation meeting for the construction of characteristic departments in the respiratory field of grass-roots institutions in Jiangsu Province, experts from the Respiratory and Critical Care Medicine Department of Jiangsu Provincial People's Hospital specifically introduced the application of Sinasol Salts in COPD to medical workers.

　　The application of salt aerosol therapy in the rehabilitation treatment of chronic obstructive pulmonary disease (COPD) has passed many clinical trials at home and abroad. The test results show that: patients with moderate and severe COPD in remission can better 'improve lung function, reduce drug consumption, and reduce the number of hospitalizations due to COPD' by using salt aerosol therapy.

　　The Xinasou Salsol Therapeutic Apparatus developed by Kuancheng Science and Technology integrates the therapy originated from nature with modern science and technology. It is the first salt aerosol therapeutic equipment to obtain medical device registration certificate in China. It is an important supplement of non drug therapy in the field of modern medical respiratory rehabilitation.

　Sinashu Salsol therapeutic apparatus Since its launch, it has received feedback from many users, and patients with COPD generally reported that the symptoms of 'cough, phlegm, asthma' and lung function test indicators have been effectively improved!
