Abstract: High-flow nasal cannula (HFNC) is a respiratory support strategy,which delivers humidified and heated oxygen at a set oxygen concentration and speed to correct respiratory failure.The failure of HFNC ventilation involves many factors,and the failure of treatment may increase the mortality.At present,respiratory rate-oxygenation index and its related predictors or models are widely used as predictors of failure in HFNC treatment,which can help identify patients at risk of tracheal intubation,but there is no uniform critical value.When using HFNC,clinicians need dynamic evaluation,and make decisions with the help of predictive factors and the actual situation of patients to improve the prognosis.
