The sound of panting was usually caused by inflammation of the respiratory tract. This kind of symptom was commonly seen in diseases such as asthma and pneumoniasis. When the respiratory tract was invaded by an allergy, it would lead to a hyperresponsive state of the respiratory tract, causing spasm of the smooth muscle of the bronchi and contraction of the trachea, resulting in breathlessness. When the air was blocked in the air passage, it would produce the sound of panting and blowing the bellows. If such symptoms occur, it is recommended to go to the hospital for examination in time, including testing for allergens, lung function, lung CT, etc., to confirm the diagnosis and carry out the corresponding treatment. Treatment methods included bronchiectomy and anti-allergy medication.
