Randomised, controlled, unblinded study on 209 patients randomyl assigned to receive oxygen or oxygen plus CPAP via helmet. Primary end point was incidence of endotracheal intubation. Authors conclude that CPAP via helmet 'may decrease the incidence of endotracheal intubation' in this scenario.

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 pilot study on 11 adult patients with acute hypoxemic respiratory failure, treated with helmet CPAP, matched with 11 control patients treated with standard face mask. Primary end points were improvements of gas exchanges and clinical parameters of respiratory distress. Authors conclude the helmet is an 'efficient alternative' to face mask treatment 'even in cases of severe respiratory acidosis and hypercapnia'.
