Children are relatively young, and if there are secretions in the middle of the trachea, there may be a whirring sound, which is related to the fact that the child’s cough reflex is weak and the phlegm from the trachea is not easily expelled from the body. In this case, you can pat the back, nebulize, and aspirate the sputum. However, the mother should not suck the child’s sputum mouth to mouth, this method is undesirable and cannot suck the sputum out of the child’s organs, on the contrary, when this operation is performed, it is easy to cause the child to suffocate, which will have a certain impact on the child’s development, in addition, infection may also occur. For example, if the sputum in the trachea is not easily drained out, the mother’s mouth has bacteria, which may breed bacteria and transmit this bacteria to the child, and the probability of respiratory infection is higher. The phlegm in the trachea cannot be drained out and is deposited at the bottom of the trachea, making it easier for pneumonia to occur. It is best to go to the hospital for a detailed physical examination and a back pat to promote the elimination of sputum. If you have to aspirate, you need to use a suction machine to do so.
