Which statement best describes the correct technique for giving CPR cycles to an infant?

• A. Use two thumbs encircling the chest to deliver compressions at a depth of 3 inches, followed by no rescue breaths.
• B. Use two fingers to deliver chest compressions at a depth of about 1.5 inches, followed by gentle breaths covering the infant's mouth and nose.
• C. Use the heel of one hand to deliver compressions at a depth of 2 inches, followed by strong breaths into the infant's mouth.
• D. Use both hands interlocked to deliver compressions at a depth of 2.5 inches, followed by rapid breaths into the infant's nose only.

Answer: (B)

Verified step by step guidance

1. Step 1: Understand the context of the problem. This question is about the correct technique for performing CPR on an infant, which is a critical life-saving procedure. CPR for infants differs significantly from CPR for adults or children due to their smaller size and fragility.
2. Step 2: Review the anatomy and physiology of an infant. Infants have smaller and more delicate chests, so the depth of chest compressions and the method of delivering breaths must be adjusted accordingly to avoid injury.
3. Step 3: Analyze the options provided in the question. Pay attention to the techniques described, including the method of chest compressions (e.g., two fingers, two thumbs, heel of one hand, or both hands interlocked), the depth of compressions, and the method of delivering rescue breaths.
4. Step 4: Recall the guidelines for infant CPR as recommended by organizations like the American Heart Association (AHA). Infant CPR typically involves using two fingers for chest compressions at a depth of about 1.5 inches, followed by gentle rescue breaths that cover both the infant's mouth and nose.
5. Step 5: Compare the correct technique to the options provided. Identify the option that matches the recommended guidelines for infant CPR, ensuring the depth of compressions and the method of delivering breaths are appropriate for an infant's physiology.
