What Are the Best Breathing Exercises for Asthma?

Exercise-induced asthma refers to a pathological phenomenon in which airway hyperresponsiveness causes acute airway stenosis and increased airway resistance after strenuous exercise. Symptoms such as cough, chest tightness, shortness of breath, and wheezing occur more than 5 to 15 minutes after the exercise is stopped. At the same time, pulmonary function related parameters decrease, and it can relieve itself within 30 to 60 minutes.

Brief introduction

Exercise-induced asthma, also known as "exercise-induced asthma", is

1. It is related to the heat exchange of the respiratory tract, that is, during the breathing process, the thermal energy is transferred from the airway mucosa to the airflow, causing the airway to cool after exercise. When the exercise stops, the airway quickly reheats, which causes air Congestion of the canal blood flow, increased permeability and edema of the mucosa, leading to narrowing of the airway and restriction of airflow.

2. The theory of osmosis: As the liquid water on the airway surface evaporates after exercise, the liquid osmotic pressure on the surface of the airway mucosa is high, which reduces the volume of nearby cells.

Chest tightness, wheezing, shortness of breath, cough, dyspnea, chest pain, and other symptoms such as stress, stomach upset, and sore throat. Some patients may not have typical asthma symptoms such as headache, abdominal pain, muscle cramps, fatigue, and abnormalities during exercise. Feeling, etc., but lung function measurements before and after exercise can find the presence of bronchospasm.

The chest is over-inflated, and the auscultation of the lungs has extensive wheezing, mainly exhalation, and the exhalation is prolonged, which can gradually relieve for about 0.5-1 hour, and the severe case can last for 2 to 3 hours, accompanied by a rapid heart rate , Cyanosis, profuse sweating, triconcavity of respiratory muscles, abnormal consciousness, etc., and even life-threatening.

First, use prophylactic drugs before exercise. Short-acting 2-receptor agonists, such as salbutamol aerosols, are usually started a few minutes before exercise.

Exercise-induced asthma persists and recurs, which can easily cause great mental and physical pain in patients. As the disease progresses, the oxygen metabolism disorder worsens. These children often show short stature, malnutrition, and humpback, and often meet similarly. Some patients with severe illnesses have developed a pessimistic disappointment or even self-abandonment. Due to insufficient attention, patients cannot be treated in a timely and reasonable manner, and some develop into bronchiectasis, which are mostly seen in the right middle lobe. Mediastinal emphysema or pneumothorax, severe cases have varying degrees of cardiopulmonary impairment, and even occur

1. 2 agonist: It has the effect of preventing and treating asthma. Inhaled 15 to 30 minutes before exercise. Once exercise asthma occurs, it can quickly relieve asthma symptoms.

2. Sodium tryptophan can stabilize mast cells, but has no bronchodilator effect. It is mainly used to prevent asthma attacks.

3. Anti-leukotriene drugs: It has a preventive effect on exercise-induced asthma, but has no relief effect on bronchospasm during the acute attack of asthma.

4, anticholinergic drugs: the effect is weak, but the diastolic effect on airway obstruction is better.

5. Glucocorticoids: Whether oral, intravenous or aerosol inhalation has no obvious immediate preventive effect on asthma attacks. But if applied regularly for a long time, it can inhibit the airway inflammation and reduce airway responsiveness, thereby preventing the onset of exercise-induced asthma.
