Purpose is to compare introduction of NIPPV (Nasal Intermittent Positive-Pressure
Ventilation) and nBiPAP (Nasal Bi-level Positive Airway Pressure) in terms of mechanical
ventilation (MV) need (non-invasive respiratory support failure) and surfactant need within
the first 72 hours of life in preterm infants with Respiratory Distress Syndrome (RDS) at
26-30 weeks of gestation.
