The Columbia Difference: The Columbia Difference: • Instituted CPAP at 5 cm H2O pressure with nasal  prongs after birth in all weight groups for signs and prongs after birth in all weight groups for signs and  symptoms of respiratory distress applied in delivery  room • Hyperventilation was avoided and PaCO2 value was  allowed to go as high as 60 mm Hg before endotracheal intubation • Muscle relaxants were not used. Minimal but adequate  ventilator settings with mechanical ventilation il i ih h i l il i • Jen‐ Tien Wung MD supervised ventilatory care full time
