Primary outcomePrimary: Peak Inspiratory Pressure — 13.45; 12.45 cmH2O — p=0.043
Summary
The purpose of this study is to test the hypothesis that neurally adjusted ventilatory assist (NAVA) will allow to lower the ventilator pressure at equivalent fractions of inspiratory oxygen (FiO2) and partial pressure of CO2 of capillary blood in preterm infants in comparison with currently used standard ventilation (synchronized intermittent mandatory ventilation with pressure-support ventilation, SIMV+PSV).
