In neonatal resuscitation, what is the preferred oxygen concentration for term infants with depressed respiration?

• A. 100% oxygen
• B. 40% oxygen
• C. 16% oxygen
• D. Room air (21%) initially; increase as needed

Answer: (D)

Start with room air and increase the oxygen concentration only if needed. Give term infants with depressed respiration just enough oxygen to support breathing without exposing them to high levels of oxygen from the start. Using 21% oxygen initially helps reduce the risk of oxygen-related injury from hyperoxia while still allowing effective resuscitation when combined with proper ventilation and airway support. You monitor the infant with pulse oximetry and adjust upward gradually—often to modest concentrations like 30–40%—until you meet targeted oxygen saturations and the heart rate improves. If those measures aren’t enough, you can escalate to higher concentrations, up to 100%, but the starting point remains room air to balance safety and effectiveness.
