Randomised trial of 15 patients undergoing three 30-minutes ventilation trials using two different helmets. The ventiltion modes were randomly applied: pneumatically triggered pressure support ventilation (PSP), neurally adjusted ventilatory assist (NAVA) and neurally controlled pressure support (PSN). The latter is a new proposed setting of the NAVA mode. Authors conclude that PSN improves comfort and patient-ventilator interactions in this scenario.

Multi-centre, randomised controlled trial across four Italian centres. Patients split into helmet CPAP and Venturi mask groups. Primary end point was percentage of patients meeting criteria for ETI. Authors conclude helmet CPAP reduces the risk of meeting ETI criteria in this scenario.

Randomised trial of 50 patients allocated to receive either continuous oxygen therapy or two cycles of helmet CPAP for 120 minutes. Results suggest that by the end of the second helmet treatment, patient's had a significantly higher PaO2/FiO2 but the improvement in oxygenation was not lasting. However, helmet CPAP was 'secure and well tolerated'.

Prospective observational study investigating effect of CPAP prior to admission to emergency room, on reduction of endotracheal intubation, in-hospital mortality and length of stay. Results showed that mortality was reduced when helmet CPAP was applied both in the pre-hospital and in-hospital settings. Authors conclude that using CPAP by trained nurses is 'safe, reduces mortality and hospital length of stay'.

Study to determine effectiveness of early CPAP delivered in the ward to prevent occurrence of ALI requiring intensive care admission for mechanical ventilation. Primary outcomes measured were need of mechanical ventilation and intubation rate among patients requiring ICU admission. Authors conclude early CPAP in this scenario prevents 'evolution to acute lung injury'.
