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'.

Comparison of application of CPAP by helmet in combination to medical therapy or used as a stand-alone procedure. In 62 patients split across the two groups, CPAP significantly improved oxygenation, reduced respiratory rate and improved hemodynamics. Based on results, authors propose 'helmet CPAP as first line pre-hospital treatment of presumed severe ACPE'.
