Clinical Trial Summary

High-frequency oscillatory ventilation (HFOV), as an ideal lung-protecting ventilation method, has been gradually used in neonatal critical care treatment, and is currently recommended as a rescue method for neonatal acute respiratory distress syndrome (ARDS) after failure of conventional mechanical ventilation. . Although its ability to improve oxygenation and enhance carbon dioxide (CO2) scavenging has been repeatedly demonstrated in laboratory studies, its impact on clinical outcomes in these patients remains uncertain. Non-invasive high-frequency oscillatory ventilation (nHFOV) combines the advantages of HFOV and non-invasive ventilation methods, and has become a current research hotspot in this field. It is recommended to be used to avoid intubation after conventional non-invasive ventilation therapy fails. For the treatment of intubation, there is still a lack of large-scale clinical trials to systematically explore its efficacy. The gradual increase in the clinical application of nHFOV has also enriched its use in the treatment of other diseases

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Partial pressure of carbon dioxide in peripheral blood	After the peripheral blood was arterialized for 10 minutes, 100 ul of the patient's finger peripheral blood was taken to measure the partial pressure of carbon dioxide in the peripheral blood.	within 50 minutes after intervention
Secondary	Asynchrony index	Asynchrony index is defined as the number of asynchrony events divided by the total respiratory rate computed as the sum of the number of ventilator cycles (triggered or not) and of wasted efforts: asynchrony Index (expressed in percentage) = number of asynchrony events/total respiratory rate (ventilator cycles +wasted efforts) × 100	within 50 minutes after intervention
