The study by Rana and colleagues in the previous issue of Critical Care identifies metabolic acidosis and a lower oxygenation index as predictors of NIV failure although it is unable to identify threshold values. It also demonstrates that treating patients with NIV for ALI ARDS and shock is an exercise in futility. Future studies need to focus on criteria that will enable selection of patients for whom NIV will have a high likelihood of success. Although noninvasive ventilation NIV has been used to treat acute respiratory failure for well over a decade our knowledge on how best to apply it continues to evolve. Relatively little debate surrounds its use for acute respiratory failure due to exacerbations of chronic obstructive pulmonary disease 1 cardiogenic pulmonary edema 2 or in immunocompromised hosts 3 . However its appropriate use to treat hypoxemic respiratory failure particularly patients with acute lung injury acute respiratory distress syndrome ALI ARDS remains unclear. In the previous issue of Critical Care Rana and colleagues 4 examine this application of NIV and identify risk factors for failure. Rana and colleagues 4 evaluated the outcomes of an .
