رضيع عمره ٤ أشهر بلا نبض، وحضر منقذان مدرّبان. ما نسبة الضغطات للأنفاس وطريقة الضغط؟

A 4-month-old infant is pulseless, and two trained rescuers are present. What compression-to-breath ratio and technique are used?

1. 15:2 with the heel of one hand on the sternum
2. 15:2 with the two-thumb encircling technique
3. 30:2 with two fingers in the mid-chest
4. 5:1 with two fingers below the nipple line

Answer: B) 15:2 with the two-thumb encircling technique. For two-rescuer infant CPR the ratio is 15:2, and the preferred technique is encircling the chest with both hands and compressing with the thumbs. A single rescuer uses 30:2 with two fingers, and the heel of the hand is for older children.
