When providing chest compressions to a 6-month-old infant, which of the following techniques is recommended?

• A. Use your thumbs side by side on the lower half of the sternum while encircling the chest with both hands.
• B. Use the heel of one hand in the center of the chest.
• C. Use both hands, one on top of the other, in the center of the chest.

Answer: (D)

Verified step by step guidance

1. Understand the anatomy of an infant's chest: The sternum (breastbone) is a flat bone located in the center of the chest, and the nipple line serves as a key landmark for proper hand placement during chest compressions.
2. Recognize the physiological differences in infants: Infants have smaller and more delicate chest structures compared to adults, so the force and technique used for chest compressions must be adjusted to avoid injury.
3. Identify the correct hand placement: For a 6-month-old infant, the recommended technique is to use two fingers (index and middle fingers) placed in the center of the chest, just below the nipple line. This ensures precise compression without excessive force.
4. Understand the rationale for the two-finger technique: This method allows for controlled compressions that are deep enough to circulate blood effectively (approximately 1.5 inches or 4 cm deep) while minimizing the risk of rib fractures or other injuries.
5. Apply the correct compression rate and depth: Perform compressions at a rate of 100-120 compressions per minute, ensuring that the chest fully recoils between compressions to allow proper blood flow.
