Approximately 50% of preterm infants less than 32 weeks require respiratory assistance at the time of transition at birth. For that stabilization during resuscitation is successful, it is essential for proper ventilation. This transition is performed with non-invasive respiratory support and administration of positive pressure ventilation to establish adequate functional residual capacity. The problem is that a peak inspiratory fixed during ventilation, and adequate tidal volume is assumed, but usually not measured, unable to correct the peak pressure to optimize ventilation and reduce lung damage. In addition, frequent adverse events may hinder or impair the effectiveness of the ventilation, with the consequent deterioration in the prognosis of the newborn.
