Multi-centre, randomised controlled trial. 47 patients admitted to ED with moderate hypoxemic acute respiratory failure (ARF) due to community-acquired pneumonia (CAP) were split into helmet CPAP or standard oxygen therapy groups. Primary end point was time to reach PaO2/FiO2 ratio > 315. The proportion of patients who reached the primary end point was also recorded. Authors conclude that CPAP delivered by helmet rapidly improves oxygenation in this scenario.

Prospective multi-centre cohort study across three European intensive care units with NPPV expertise, resulted in survey of 479 patients with ARDS. Authors conclude NPPV applied as first-line intervention avoided intubation in 54% of treated patients.

Comparison study of nCPAP through helmet vs face mask on 17 patients with moderate to severe acute respiratory failure. Arterial oxygen saturation, heart rate, respiratory rate and blood pressure were measured. Authors conclude early nCPAP with helmet imrpoves oxygentation in this scenario.

Prospective clinical pilot investigation on 33 patients treated with noninvasive pressure support ventilation (NPSV) delivered by helmet. Each patient was matched with two controls with ARF treated with NPSV via a facial mask. Primary end points were improvement of gas exchange, need for endotracheal intubation and the complications related to NPSV. Both groups improved oxygenation after NPSV, less patients failed NPSV and were intubated in the helmet group and less complications occured, while longer continuous application of the tecnique was possible. Authors concluded that NPSV by helmet successfully treated hypoxemic ARF, with better tolerance and fewer complications than facial mask NPSV.
