It is normal to hear breath sounds in the lungs when breathing, and to hear them more clearly when the ear is pressed against the chest wall or with a stethoscope. If you don’t use a stethoscope, it is not normal to hear rough sounds from a distance, mainly due to bronchitis, pneumonia, bronchial asthma and other diseases. When there is bronchial asthma, the breath sounds will be more rapid and there will be phlegm sounds, which need to be treated with bronchodilator drugs. Various respiratory tract infections can cause excessive secretions, which can be sticky and obstruct the airway, and when the airflow of breathing passes through the narrow airway, it will make abnormal sounds, which need to be actively treated with anti-inflammatory and anti-viral drugs, and also need to be treated with drugs to stop coughing and resolve phlegm, such as amoxicillin, amoxicillin granules, and snake bile and Chuanbei liquid.
