 During spontaneous breathing the continuous positive airway pressure CPAP provided with the new system is more pressure stable and has low imposed work of breathing. The benefits of decreased imposed work of breathing during resuscitation have not previously been investigated. The new system has the option of using prongs as the patient interface. Prongs have shown promising results in trials and have theoretical benefits. We hypothesis that the combined use of prongs and low imposed work of breathing could reduce the number of infants that need mechanical ventilation.
