High-frequency oscillatory ventilation (HFOV), as an ideal lung-protecting ventilation method, has been gradually applied to neonatal intensive care treatment, and is currently recommended as a rescue method for neonatal acute respiratory distress syndrome (ARDS) after conventional mechanical treatment fails. ventilation. Non-invasive high-frequency oscillatory ventilation (nHFOV) combines the advantages of HFOV and non-invasive ventilation methods, and has become a research hotspot in this field. Recommended to avoid intubation after failure of conventional non-invasive ventilation therapy. There is a lack of large-scale clinical trials systematically exploring its efficacy for intubation therapy. The increasing clinical application of nHFOV has also enriched its application in the treatment of other diseases. Human-machine asynchrony during non-invasive ventilation will seriously affect its efficacy, but no one has reported on the research related to nHFOV human-machine asynchrony.

Asynchrony index
Asynchrony index is defined as the number of asynchrony events divided by the total espiratory 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
