Wheezing with the sound of pulling a bellows is actually the respiratory sound of the airways. It is often seen in wheezing bronchitis or bronchial asthma, which is caused by ventilation dysfunction of the airways and expiratory dyspnea. It is recommended to test chest radiographs, check lung function, blood tests, and allergens if necessary. Nebulized inhalation therapy can be used, and the drugs used for nebulized inhalation can be bronchodilators, glucocorticosteroids, and drugs to relieve bronchospasm, and anti-allergic drugs. Based on the results of these tests, a comprehensive assessment is made to make a definitive diagnosis and adjust the treatment program at any time.
