In infant cardiopulmonary resuscitation (CPR), how many chest compressions should be delivered per cycle before giving breaths to a 4-month-old infant?

• A. 15 compressions
• B. 10 compressions
• C. 20 compressions
• D. 30 compressions

Answer: (A)

Verified step by step guidance

1. Understand the context: Infant CPR is a life-saving procedure performed on infants under 1 year of age to restore circulation and breathing during cardiac arrest. The technique differs from adult CPR due to anatomical and physiological differences in infants.
2. Review the guidelines: According to the American Heart Association (AHA), infant CPR involves cycles of chest compressions followed by rescue breaths. The number of compressions per cycle is standardized based on evidence-based practices.
3. Identify the correct compression-to-breath ratio: For infants, the recommended ratio is 15 chest compressions followed by 2 rescue breaths when performed by two rescuers. If only one rescuer is present, the ratio changes to 30 compressions followed by 2 breaths.
4. Consider the age of the infant: The problem specifies a 4-month-old infant, which falls under the category of infant CPR guidelines. Ensure the compressions are performed using two fingers or thumbs, depending on the number of rescuers.
5. Apply the correct technique: Chest compressions should be delivered at a depth of approximately 1.5 inches (4 cm) and at a rate of 100-120 compressions per minute. After completing the specified number of compressions, provide rescue breaths to ensure oxygen delivery.
