Effective removal of airway secretions requires a balance between the production and removal of airway secretions through the mucociliary transport system. Effective removal of airway secretions is the basic measure to maintain airway patency and normal alveolar ventilation and oxygenation. At present, a variety of mechanical assisted expectoration devices have been used to remove airway secretions in critically ill patients, including The MetaNeb® System(MetaNeb), High Frequency Chest Wall Oscillation(HFCWO) and (Cycloid Vibration Therapy)CVT. However, there is still a lack of sufficient evidence to evaluate the clinical efficacy of these three different mechanical assisted expectoration devices in airway management of patients with mechanical ventilation. This study aims to observe the clinical efficacy of three different mechanical assisted sputum evacuation devices in airway management of patients with mechanical ventilation atelectasis, and to provide a basis for optimizing the airway management scheme of patients with mechanical ventilation.",[44,45],"Mechanical Ventilation","Atelectasis","NOT_YET_RECRUITING","2024-10-06",{"date":49,"type":50},"2024-10-08","ACTUAL",{"date":52,"type":39},"2024-11-01",{"date":54,"type":39},"2025-12-01",{"name":5,"class":6}]
