One-person rescuer infant technique?

• A. Two thumbs encircling hands
• B. Fist with one hand
• C. Chest compressions with both hands
• D. Two parallel fingers

Answer: (D)

In one-person rescuer infant CPR, chest compressions are delivered with two parallel fingers placed on the center of the infant’s chest just below the nipple line. This two-finger position provides precise, controlled compressions that reach about 1.5 inches (roughly 4 cm) or about one‑third of the chest’s depth, at a rate of 100–120 per minute with full recoil between compressions. This method is ideal for a single rescuer because it fits the small, delicate infant chest and minimizes injury while still delivering effective circulatory support. The two thumbs encircling the chest is a technique used when there are two rescuers, allowing deeper or more stable compressions. Using a fist with one hand isn’t appropriate for an infant due to the risk of injury to the soft chest and ribs.
