What is the initial recommended oxygen concentration for resuscitating a term infant with depressed respiration?

• A. 21% room air
• B. 100% oxygen
• C. 30%
• D. 15%

Answer: (A)

Initiate resuscitation with room air (about 21% oxygen) for a term infant with depressed respiration. This starting point provides sufficient oxygen while reducing the risk of oxygen toxicity that comes with high concentrations. After beginning, monitor the infant with a pulse oximeter and titrate oxygen upward only if the preductal saturations remain low or the heart rate does not improve, aiming for progressively normal ranges over the first several minutes. In many term babies, ventilation and gentle stimulation with room air are enough, and escalating to higher oxygen is reserved for situations where oxygenation stays inadequate or there is poor perfusion. The goal is to balance adequate oxygen delivery with avoiding unnecessary hyperoxia.
