This single-centre, non-blinded RCT of ICU ARDS patients, found that NIV delivered by a novel helmet, as compared to a standard NIV facemask, reduced intubations (18.2% vs. 61.5%; P <0.001) and hospital mortality (27.3% vs. 48.7%; P= 0.04). Despite its few methodological flaws, this study supports the existing literature on the advantage of oxygen delivered via helmet over facemask in avoiding intubation in ARDS, and future studies should focus on its impact in heart failure or hypercapneic respiratory failure.
