How to do a good job in emergency self-rescue of bronchial asthma in spring

The occurrence of bronchial asthma, because of many inducing factors, such as all kinds of dust mites in the family, parasitic in people's dandruff, hair and other objects, coupled with the suitable climate after spring, a variety of pathogenic pathogens will greatly reproduce and breed, thus paying great attention to the prevention, it will inevitably make bronchial asthma relapse. Especially for those groups with weak resistance, such as infants, children and the elderly, the recurrence is significantly enhanced. Therefore, it is necessary for themselves and their families and relatives to master the necessary self-rescue methods of acute attack.

All patients who have suffered from bronchial asthma and their families and relatives will know some or comprehensive emergency methods for acute attack of bronchial asthma. In fact, the patients themselves and their families and relatives should first establish the concept of mastering this kind of first aid common sense. Because of the dense recurrence factors of bronchial asthma, the recurrence rate is very high, and the symptoms will gradually aggravate after recurrence, which requires continuous follow-up of first aid.

The premise of mastering the first aid method of bronchial asthma is to understand and identify the symptoms that need first aid. Once patients or family members find allergens such as colds or contact with pollen, there are many or one significant symptoms such as itchy nose, itchy pharynx, sneezing, dry cough, runny nose, chest contraction, and so on, they should be paid attention to, such as getting rid of allergen interference, making patients calm down, taking deep breaths, and avoiding further development.

For patients with recurrent or recurrent bronchial asthma and their relatives, they must carry short-acting β 2-receptor agonists such as salbutamol aerosol or emergency drugs such as budesonide formoterol powder inhalation. If the patient has worsened bronchial asthma, he or she must be accompanied by family and relatives for a long time, and carry first aid agents such as simple peak respiratory flow meter (PEF), salbutamol aerosol and other short-acting β 2-receptor agonists. Once patients have acute symptoms, they should use PEF self-test and record. Inhaled short-acting β 2-receptor agonists, 2-4 drops at a time.

Salbutamol aerosol

After 15 minutes, use PEF self-test, return to the usual maximum value of 50%-80%, spray or inhale every 20 minutes within an hour, 2-4 drops each time, and add a small amount of theophylline controlled-release tablets. If the PEF self-test after 15 minutes shows that the recovery rate is less than 50%, inhaling emergency agents such as short-acting β 2-receptor agonists every 20 minutes within 1 hour, plus taking a small amount of theophylline controlled-release tablets, oral prednisone tablets 20~30mg, and contact for medical treatment as soon as possible.

A simple respiratory peak flow meter (PEF)

For an acute attack of bronchial asthma, when there is no medical treatment, after self-test and spray treatment, the self-test should be carried out again at an interval of 15 minutes. When the PEF test reaches the normal expected value 15 minutes after treatment, or 80% of the usual highest value, first aid agents such as short-acting β 2-receptor agonists can be sprayed or inhaled every 3-4 hours, still 2-4 drops each time. At present, PEF (simple respiratory peak flow meter) is not yet popular. Without this kind of self-test, first aid agents such as β 2-receptor agonists should be inhaled every 20 minutes within an hour, and if theophylline controlled-release tablets and prednisone tablets are not added in the subsequent inhalation, if there is no obvious effect in self-rescue within 1 hour or 2 hours, you should see a doctor as soon as possible.
