去痰有很多方法，看治疗支气管扩张和cystic fibrosis的去痰方法。 但不一定适合新冠

去痰有很多方法，看治疗支气管扩张和cystic fibrosis的去痰方法。 但不一定完全适合新冠，因为三者病因不同。 关键还是要根本上解决，让过量粘液不能产生。难就难在这里。  By the way, 中国孩子有CF 的很少， 谢天谢地， 老天保佑！！！当然治疗经验也少。美国儿童肺科医师主要看CF和哮喘。。。

How do you reduce mucus in bronchiectasis?

Medicines may be inhaled to help open the airways and loosen mucus. A bronchodilator such as albuterol or levalbuterol can help relieve or prevent spasm of the airway muscles. Hypertonic saline is a concentrated salt water solution that can help loosen secretions in your airways.
