The climate is changeable in early spring. How to prevent cor pulmonale and bronchial diseases-

In early spring, the climate is changeable, and it is warm and cold at first. For middle-aged and elderly people with chronic bronchitis or chronic cor pulmonale, if health care is neglected, respiratory infection can easily lead to the recurrence and aggravation of cor pulmonale. Therefore, early prevention should be done in early spring, and the following points should be done.

Stay away from the smog. Haze contains compounds such as nitrogen and sulfur, and harmful components such as industrial dust and particulate matter (PM2.5, PM 10) in smog can cause chemical and physical damage to respiratory tract. Small particles such as PM 2.5 will be deposited in the lungs, which will reduce alveolar elasticity and respiratory function, and bacteria will take advantage of it, causing respiratory infection and leading to acute attack of cor pulmonale. Therefore, in foggy weather, you must not go out. If you want to go out, you must wear a dust mask, you must not smoke and stay away from second-hand smoke.

Be cold-proof in early spring. In early spring, the cold wind is chilly. Once stimulated by cold, submucosal blood vessels of upper respiratory tract contract, blood flow is blocked, airway is ischemic, and immunity is reduced, which easily leads to virus and bacterial infection. Therefore, we should add clothes in time according to the weather changes and drink more hot water to avoid catching a cold. Keep exercising. Patients with chronic tracheitis and cor pulmonale should insist on moderate exercise, such as walking, jogging, doing radio gymnastics, playing Tai Ji Chuan, dancing, and riding a bike. It can enhance airway and cardiopulmonary function, improve adaptability and resistance to external climate change, and play a role in preventing infection and recurrence. Have a regular life. Regular life, combining work and rest, ensuring more than 8 hours of sleep at night, taking a nap 1 hour, and taking a good rest can reduce the burden on the heart and be good for cardiopulmonary function.

Diet should be taboo. People with cor pulmonale should be supplemented with protein, vitamins, minerals and other nutrients, such as fish, eggs, poultry, lean meat, bean products, fresh vegetables, fruits, etc., which is conducive to repairing the damaged bronchial mucosa. Eat more pears, lilies, honey, yam, fresh dates, etc. to nourish yin, nourish body fluid and moisten lungs, improve emergency response ability and resist the recurrence of infection.

In addition, we should pay attention to replenish water and drink boiled water every day to keep the respiratory tract moist, which is conducive to the smooth cough of sputum. Avoid eating cold, overheated and spicy food, so as not to stimulate the throat and tracheal mucosa and cause paroxysmal cough. Eat less food rich in crude fiber to prevent flatulence and affect breathing.

The most important thing is to eliminate phlegm. Phlegm retention in trachea will not only aggravate dyspnea, but also easily induce infection. If there is phlegm, try to cough it up. If there is sticky phlegm, it is not easy to cough it up. You can inhale steam or atomize and dilute the thick sputum to help cough up and keep the respiratory tract unobstructed.

Keep a good mood. Emotion is very important to the health and life safety of patients with cor pulmonale. Besides caring more, solving problems for patients and friends, establishing confidence in overcoming diseases, and being optimistic and cheerful are conducive to the balance of physiological functions of viscera. Smooth qi and blood, enhanced resistance, will effectively improve immunity. Timely prevention and control. When infectious diseases are prevalent in spring, avoid going to crowded public places and other people's homes. Middle-aged and elderly people with poor health can be injected with influenza vaccine, pneumococcal vaccine, immune enhancer and so on. To reduce the chance of infection. Once a respiratory infection occurs, you should go to the hospital as soon as possible, treat it in time and recover as soon as possible.
