1, pay attention to the disease of bronchial asthma, understand the knowledge of bronchial asthma, and improve the level of awareness of bronchial asthma. 2.Avoid or reduce exposure to risk factors as much as possible to prevent asthma attacks and exacerbation of symptoms. ①No smoking and avoid passive smoking; ②Keep the room clean; ③Avoid contact with flowers; ④Avoid inhalation of irritating gases; ⑤Avoid food allergy or irritating food; ⑥Avoid allergy to drugs; ⑦Identify early life or occupational allergens and prevent further contact; ⑧Avoid strenuous exercise and emotional excitement; ⑨The indoor temperature and humidity should be appropriate to avoid getting cold and avoid respiratory tract infection. 3. Recognize and manage acute asthma attacks. ① Manifestation of acute bronchial asthma attack: acute bronchial asthma attack refers to shortness of breath, cough, chest tightness or a combination of these symptoms, episodic and progressive aggravation. Bronchial asthma attacks are often preceded by aura symptoms such as itchy eyes, itchy ears, itchy nose, sneezing, runny nose, frequent irritating cough, and chest tightness. ② Self-emergency treatment for acute bronchial asthma attack: first inhale short-acting β2 agonists (Ventolin, Asthmacontrol), etc., 2-4 sprays each time; if it does not relieve, repeat after 20 minutes; if it still does not relieve after 3 repetitions, go to the hospital emergency room promptly. ③Patients should seek medical help immediately when they have the following conditions: severe acute attack; delayed response to initial bronchodilator treatment that lasts at least 3h; no improvement 2-6h after the start of oral glucocorticosteroid treatment and further deterioration of the condition. 4. Standardized medication: Firstly, we should eliminate the rejection of the use of hormones, and secondly, we should master the inhalation technique. It is necessary to master the basic uses and correct usage of relevant drugs, as well as the correct use of inhalation aerosols; the use of fog cans in younger patients can reduce the difficulty of use and enhance the effectiveness of inhalers. 5.Monitoring and evaluation of asthma: the more common methods of monitoring and evaluating asthma in clinical practice are: asthma severity grading, asthma control test, peak expiratory flow rate monitoring, Asthma Control Questionnaire (ACQ), 30-second asthma control test (30-second), etc. asthma control test), etc. Among them, asthma severity grading, asthma control test and peak expiratory flow rate are easy to operate and have been widely validated. 6.Regular follow-up: Patients should have a follow-up visit within 1 week after the initial diagnosis, clear diagnosis and treatment plan is given to evaluate the treatment, and the doctor will again provide health education and guide the standardized use of drugs. The patient should return 2-4 weeks after the initial control of the disease, and every 1 month thereafter. If an asthma attack occurs, the patient should be seen in a timely manner, and a return visit should be made within 2 weeks to 1 month after the asthma attack. 7.Physical exercise: If conditions allow, bronchial asthma patients should do cold-tolerance exercise, respiratory function exercise and whole-body physical exercise; this can improve the cold-tolerance ability of the body, enhance physical fitness, prevent or reduce allergy, strengthen respiratory muscle function and whole-body physical fitness, improve immunity and prevent external sensation. Cold exercise has a cold bath, cold water washing, cold water irrigation nasal cavity and other forms; respiratory exercise to breathing exercises, including lip-snorting, abdominal breathing, etc.; physical exercise in the form of jogging, cycling and other aerobic exercise. However, all the above exercises are appropriate in moderation and should be done gradually to increase the amount of exercise; do not be too cold or too much exercise to avoid inducing external sensation or asthma attack. Of course, exercise should be restricted during acute bronchial asthma attacks.
