Delayed intubation after NIV / HFNC failure is associated with high mortality rate in acute respiratory failure patients.~There are Many factors to predict early failure but World still searching for new factors and comparing between each ;in order to eatablish best one that achieve the least mortality rate.~Little studies about effiecacy of HACOR Score as a predictor of failure in HFNC patients.~Little studies about effiecacy of ROX Index as a predictor of failure in NIV ventilating patients.
Comparison between some predictors of failure of non-invasive ventilation and high flow nasal cannula.
