Atelectasis refers to the atrophy of lung tissue or the reduction of gas volume in the lung,caused by various factors,resulting in decreased lung volume.This adverse health condition affects normal respiratory function,and atelectasis caused by airway secretion blockage is a common issue in children.Drug treatments for this condition has limited effectiveness.Airway clearance therapy facilitates the drainage and vibration of airway secretions,thereby enhancing the clearance of these secretions.These techniques could enhance the airway's ability to clear secretions,improve gas exchange,and alleviate dyspnea.Therefore,they have been regarded as an effective rehabilitation method for treating atelectasis.Nowadays,airway clearance therapy is becoming increasingly mature and is widely used in the management of severe pediatric respiratory diseases.This article systematically summarizes the latest research progress in airway clearance therapies for children,based on both domestic and international research,to enhance the understanding of airway clearance therapies for children and provide ideas and references for the rehabilitation treatments of children with atelectasis.
