Under the situation of epidemic prevention and control, the coming of the autumn and winter influenza season will be a severe test for COPD patients. The reduction of temperature will lead to the decline of the patient's immunity, the body is more susceptible to virus invasion, some patients will appear for two or three months of cough, asthma, causing acute exacerbation of COPD, severe respiratory failure. Once people with COPD get the flu, they are more likely to develop severe flu and have an increased risk of death.

　　Copd is a high-risk group for influenza

　　Respiratory physicians have a saying about COPD: 'COPD is a long and painful funeral.' Respiratory failure is one of the leading causes of death in patients with COPD. The main cause of respiratory failure is infection, including the influenza virus, and people with COPD are at high risk for influenza. According to the CHEST 2019 study:

　　1. Among those hospitalized with COPD, patients with influenza infection required mechanical ventilation more frequently (8.7% vs. 5.2%), had higher crude mortality (9.7% vs. 7.9%), and had higher critical care requirements (17.2% vs. 12.1%) than those without influenza.

　　2. The crude mortality rate (11.2%) and the incidence rate of critical illness (18.1%) were higher in patients with chronic obstructive pulmonary disease complicated with influenza.

　　Influenza can cause an acute exacerbation of COPD

　　Influenza is a common acute upper respiratory viral infection disease, usually caused by rhinovirus, adenovirus, respiratory syncytial virus and so on. Upper respiratory virus infection, clinical manifestations of stuffy nose, sneezing, runny nose, fever, cough, sore throat, headache and other common cold symptoms. Normal upper respiratory tract infection generally does not spread to the lower respiratory tract, but COPD patients with chronic airway inflammation, impaired airway barrier function, poor resistance to viruses, easy to spread to the lower respiratory tract, lower respiratory tract infection, resulting in acute exacerbation of COPD.

　　Respiratory tract infections caused by bacteria, viruses, etc, will improve the level of eosinophils and neutrophils, increases in patients with airway inflammation, inducing copd acute episodes, cause serious decline in lung function, increase the symptoms of shortness of breath, cough, and even can be complicated by pulmonary embolism, arrhythmia, such as serious pathological changes, endanger the patient's life.

　　New ways to protect people with COPD during flu season

　　Copd has a characteristic, is the progressive disease, every cold, fever, lung function will decline a little, so usually to do a good job of protection, beware of cold. Home recuperation, recommended use of Sinashu small rock salt aerosol therapeutic instrument. Prevention and treatment of respiratory diseases can effectively relieve the symptoms of COPD and reduce the incidence of the disease. Mainly in the following aspects:

　　1, salt aerosol therapy through the inhalation of salt particles, into the respiratory tract, terminal bronchioles, alveoli, help COPD patients with airway expansion, ensure smooth breathing.

　　2. Enhance mucociliary clearance, change the rheology of bronchial mucus, dilute sputum, enhance mucociliary swing activity, and promote sputum discharge.

　　3. Activate the innate immune antiviral signaling pathway of alveolar macrophages, enhance their phagocytosis activity, improve pulmonary immunity, effectively reduce the frequency of onset and alleviate symptoms.

　　4, Sinashu salt sol therapeutic instrument can eliminate 99.9% of the influenza virus in 30 minutes. Safe ingredients, no side effects. Prevent the spread of influenza virus and protect the health of the whole family.

　　5, non-drug treatment, high compliance, safety and health, home can also enjoy medical convalescence.

　　Warm tips: COPD is prone to attack when the climate suddenly gets cold. Keep warm, add clothes in time, and keep the indoor temperature relatively stable. Wear a mask when going out, do not contact people with colds and fevers, and do not go to crowded places with poor air circulation.
