Acute respiratory distress syndrome: Predictors of noninvasive ventilation failure and intensive care unit mortality in clinical practice

Noninvasive ventilation maybe useful in selected patients with mild ARDS but should be used with great caution in moderate and severe ARDS, as failure risk is high. In addition, low Pao2/Fio2 and shock are associated with NIV failure. Acute Physiology and Chronic Health Evaluation II score, shock, low Pao2/Fio2, and ARDS severity are associated with increased mortality.
