A preterm infant (32 weeks gestation) is delivered via emergency cesarean section for fetal distress. At 1 minute, the infant has an APGAR score of 3 (heart rate 80 bpm, no respiratory effort, limp tone, no reflex irritability, pale). At 5 minutes, the score is 5 (heart rate 100 bpm, weak cry, minimal flexion, grimace, acrocyanosis). What is the most appropriate next step in management?
