Lifeguarding Practice Test – Complete Exam Preparation

In two-rescuer CPR for an infant, the recommended cycle is indeed 15 chest compressions followed by 2 ventilations. This protocol is specifically designed to provide effective circulation and oxygenation for infants, who have different physiological needs compared to adults or older children.

The focus on performing 15 compressions allows for a rapid and adequate blood flow, ensuring that the heart can pump blood effectively. Following the compressions with 2 ventilations helps to reintroduce oxygen into the lungs, which is critical for the infant's survival. This sequence is set to optimize the chances of restoring a normal heart rhythm and providing sufficient oxygenation until advanced medical help can arrive.

Understanding this rhythm and sequence is vital for all rescuers, as it maximizes the effectiveness of CPR in very young patients, where both timing and technique are crucial to outcomes in a cardiac emergency.
