Mid and Standard Frequency Ventilation in Infants With Respiratory Distress Syndrome

The purpose of this study is to determine, in preterm infants less than 37 weeks gestation with respiratory distress who are ventilated in the first 48 hours after birth, if mid frequency ventilation strategy using ventilator rate of ≥ 60 to ≤ 150 per minute compared with standard frequency ventilation strategy using ventilator rates of ≥ 20 to \< 60 per minute will increase the number of alive ventilator-free days after randomization and reduce the risk of ventilator induced lung injury.
