What is Asthma? Why is an asthma attack so fatal?

Asthma is an allergen-induced spasm of bronchial smooth muscle, resulting in airflow restriction manifested by cough, chest tightness, stridor, audible stridor in the lungs, abnormal lung function, and obstructive ventilatory dysfunction. Bronchial provocation test and bronchiectasis test were positive, and the blood routine showed eosinophilia, dyspnea, airflow limitation, chest tightness, and difficulty expiring during nocturnal asthma attacks. Severe asthma can be life-threatening in ten minutes or even minutes, due to severe bronchospasm that causes severe narrowing of the airways.

Sudden thinning of the trachea can cause hypoxemia and hypercapnia. Patients are unable to breathe in oxygen or exhale carbon dioxide, which can lead to a series of serious diseases such as a drop in blood pressure, loss of consciousness, and respiratory and cardiac arrest. Consequence.

Asthma can cause a symptom of dyspnea, which is likely to pose a threat to the person's life if there is no timely intervention. Because there is no way to breathe on their own after an asthma attack, if they do not get oxygen in time, it will pose a threat to their lives.

It is a disease of the lungs that can sometimes lead to serious complications. It can cause you to have trouble breathing and you may eventually suffocate to death.

Probably the most important trigger for asthma is inhaled allergens. Indoor allergens House mites are the most common and most harmful indoor allergens and are important triggers for asthma worldwide. There are 4 common types:

House dust mites, dust mites, dust mites and polychaete mites. If a person with asthma has a severe acute exacerbation, it can be fatal if not treated promptly. Patients with poorly controlled asthma will have an impact on daily work and daily life, which can lead to missed work and school, limited activities and exercise, reduced quality of life, and financial burden and negative impact on the life of family members.

Severe asthma, which can be life-threatening in minutes or even minutes, is due to severe spasm of the bronchial tubes, which causes severe narrowing of the airways. The trachea becomes thinner all of a sudden, causing hypoxemia and hypercapnia, and the patient cannot breathe in oxygen or exhale carbon dioxide, which will cause a series of serious consequences such as a drop in blood pressure, loss of consciousness, and respiratory and cardiac arrest.

Asthma is actually bronchial asthma, which is a chronic inflammation of the airways. The fatal cause of the seizure is severe narrowing of the airways due to severe spasm of the bronchial tubes.

Asthma is an example of a respiratory disease. Because when you have an asthma attack, you won't be able to breathe, and you won't have blood flow, and you'll die.

Asthma is a serious respiratory disease, so asthma patients must not be too emotionally fluctuating, and should be calm, so as to reduce the occurrence of asthma. So what causes asthma attacks?

We need to know that asthma patients breathe very quickly, they are not able to do strenuous exercise, if they do strenuous exercise, it may cause breathing problems and asthma attacks. Therefore, asthma patients are not able to do some strenuous exercise, they can do some aerobic exercise, avoid asthma, and they are not able to eat foods that are easy to cause allergies. If you have asthma, be sure to go to the hospital to check the allergens and avoid these allergies in your daily life, so as to reduce the frequency of asthma attacks and make your body more comfortable.

Many foods in life can cause allergies, such as some shrimp and fish. So if you are an asthma patient, you must do an allergy test when eating salmon, and you can't eat it directly, if you eat it directly, it may cause allergies and then make your asthma attack.

As mentioned above, asthma patients should not be too excited, if they are too excited, it will cause the nerves in the cerebral cortex to overreact, and it will also cause asthma. Therefore, in daily life, asthma patients must be a little more open-minded, not too careful, if too careful, it may cause problems in your body. Patients must maintain a healthy mood and not have too drastic fluctuations, which can also trigger asthma.

Therefore, when facing asthma patients, we must not let them get too angry, we must calm them down and make their mood calm.

The first is psychological, nervousness and emotional agitation can contribute to asthma attacks, which are generally thought to be caused by cerebral cortex and vagus nerve reflexes or hyperventilation.

The second is exercise and hyperventilation, and 70%-80% of patients induce asthma attacks after strenuous exercise, which is called exercise-type asthma.

The third is the change of climate, which can induce asthma when there is a change in temperature, humidity, air pressure, and ions in the air, so it is more likely to occur during the cold season or the transition between autumn and winter.

Fourth, air pollution, which has been shown to cause acute exacerbations of asthma.

Fifth, menstruation, pregnancy and other physiological factors, many women during menstruation or pregnancy, will have aggravation.

It may be because the body can't bear it for a while when you go to a cold or overheated environment, or you have an asthma attack caused by an allergen.

1. First of all, you must be calmHave the patient sit with their forearms on a small table and their back against a pillow, keeping their shoulders warm.

2. Give the patient spiritual comfort:Gain the patient's trust in terms of language and attitude, reduce the patient's anxiety and nervousness, and reduce the body and oxygen consumption.

3. Enhance airway resistanceIf sputum obstructs the airway, it can increase airway resistance, aggravate hypoxia and dyspnea, and the patient should be actively promoted to produce sputum and keep the airway open4. Oxygen inhalationOxygen can be given with a nasal ventricle or a double-lumen nasal cannula.

Oxygen flow rate 1-3 liters. Oxygen must be humidified.

5. Correctly instruct patients to inhale anti-asthma drugs, keep warm, and properly replenish fluidsIf the patient's dyspnea persists, the emergency service should be called**.

1. Dietary care:Avoid eating things that you haven't eaten before, and eat more fresh vegetables and fruits, such as radish, pumpkin, loofah, cucumber, bitter gourd, watermelon, winter melon, tomatoes, pears, citrus, loquat fruits, etc. You can eat more lung-nourishing foods such as sesame seeds, walnut kernels, cooked almonds, honey, fungus, mushrooms, etc.

2. Physical care:Usually pay attention to cold and warmth, strengthen nutrition, enhance physical fitness, and prevent colds.

3. Nursing care in terms of daily lifeIn terms of clothing materials, patients with bronchial asthma should not wear acrylic, polyester and other chemical fiber clothing, wool underwear, duck down vests, and animal fur clothing, which are easy to cause allergies, urticaria, and bronchial asthma.

Fourth, pay attention to exercise:One of the goals of bronchial asthma** is to be able to perform daily activities and some level of physical activity. The key is to avoid triggers and monitor symptoms and lung function regularly.

Patients with bronchial asthma can swim, jog, brisk walk, ride a bike, do aerobics, etc., 4 to 5 times a week, for at least 30 minutes each time.

Fifth, home layout:The living room of patients with bronchial asthma should be sunny, well-ventilated, and simple; Do not place flowering plants in the living room; Do not keep pets such as dogs, cats, and birds at home; Do not use carpet on the floor and keep the floor clean and dry.

Asthma attack, what to do?

Asthma is a genetically predisposed disease, and patients are generally allergic, and most of them can find allergens; After the allergen is found, if there is an indication for immunity** (some people call desensitization**), if the drug** is not effective, immunity** can be considered**; Immunization** can only reduce the symptoms, not completely**, and allergies and asthma will occur in the future.

Asthma in general, most of which are caused by infections, such as respiratory syncytial virus, Mycoplasma pneumoniae, chlamydia and other infections, can present with asthma-like symptoms. (
