High-frequency chest wall oscillation multiple times daily can better reduce the loss of pulmonary surfactant and improve lung compliance in mechanically ventilated patients

In intensive care unit patients, the prevalence of ventilator-associated lung injury continues to be high due to the patient's severe organ dysfunction and specific treatment measures such as analgesia sedation and external pipeline management 1.2. The causes are related to dysfunction of airway secretion clearance, edema caused by pulmonary capillary permeability changes, lung compliance, and respiratory muscle weakness caused by ICU-acquired weakness3. Airway clearance techniques (ACT) are needed to coordinate airway secretion clearance and pulmonary function rehabilitation in severe cases.
