A 1.05-kg female infant was born at 29 weeks' gestation by emergency cesarean section. The Apgar scores were 6 and 8 at one and five minutes, respectively. The infant was intubated and subsequently ventilated with a fraction of inspired oxygen of 0.7 (maximum, 0.8) at an initial rate of 44 breaths per minute (maximum, 68 breaths per minute) and pressure of 25/2 cm H2O (maximum, 30/3 cm H2O). Her initial chest roentgenogram was compatible with severe idiopathic respiratory distress syndrome (IRDS), with a complete "whiteout" of both lungs.
