The Chinese New Year is approaching, the whole country began to enter the atmosphere of the Spring Festival, but we have to face a grim fact: Although many places have begun to ban fireworks in recent years, but there are still some areas are not fully banned, thus making air pollution further aggravated than usual, air quality is seriously affected. Air pollution often triggers or aggravates respiratory diseases, especially chronic obstructive pulmonary disease. Therefore, how to spend the Spring Festival safely, has become a topic of concern for many patients with chronic obstructive pulmonary disease. 1, to actively quit smoking, to avoid inhaling harmful particles in the air Smoking is a risk factor for the occurrence and development of chronic obstructive pulmonary disease, once diagnosed, must resolutely quit smoking. At the same time, harmful particles in the air, like smoking, can also induce and aggravate chronic obstructive pulmonary disease. 2.Giving long-term home oxygen therapy and pulmonary rehabilitation training Research shows that long-term home oxygen therapy can significantly improve the hypoxic condition of patients with slow obstructive pulmonary disease, thus improving the quality of life and prolonging the survival of patients with slow obstructive pulmonary disease. At the same time, we encourage patients with chronic obstructive pulmonary disease to master some pulmonary rehabilitation training skills, such as lip retraction breathing, abdominal breathing and breath-holding breathing, etc. 3.Actively prevent upper respiratory tract diseases such as common cold and acute bronchitis Various upper respiratory tract diseases are the triggering factors for the exacerbation of chronic obstructive pulmonary disease in patients. In daily life, it is recommended that patients with chronic obstructive pulmonary disease should wash their hands regularly, avoid touching their nasal cavity and mouth and lips without washing their hands, adjust their clothing according to the temperature change and pay attention to keeping warm. 4.Enhance immunity Influenza vaccination and pneumonia vaccination in autumn and winter can prevent the occurrence of upper respiratory tract infections to a certain extent, thus reducing the probability of a slow-onset lung attack. In addition, for patients with chronic obstructive pulmonary disease, appropriate consumption of high-protein foods and fresh vegetables and fruits can also enhance immunity and reduce recurrent attacks of the disease. 5, active drug prevention, regular monitoring of lung function For patients with poor lung function classification, long-term maintenance use of bronchodilators and inhaled glucocorticoids is also required in the stabilization phase, and lung function is reviewed every six months to adjust the use of drugs according to the degree of lung function progression. In general, only with the synergistic treatment of medication and lifestyle habits can patients with chronic obstructive pulmonary disease survive the autumn and winter months when the temperature drops and haze is high, especially during the Chinese New Year.
