What is the compression-to-breath ratio for CPR performed by a single rescuer on an infant?

The compression-to-breath ratio for CPR performed by a single rescuer on an infant is 15:2. This ratio signifies that for every 15 chest compressions delivered to the infant, the rescuer should provide 2 breaths.

This specific ratio is designed to optimize the balance between effective chest compressions, which help circulate blood during cardiac arrest, and rescue breaths, which provide essential oxygen to the lungs and subsequently to the brain and other vital organs.

In the case of infants, a greater number of compressions relative to breaths is often recommended to ensure a higher frequency of blood circulation, which is critical in this vulnerable population. The 15:2 ratio helps achieve a good compromise that prioritizes chest compressions while still addressing the need for oxygenation. This is especially important because infants have a smaller airway and are more susceptible to inadequate ventilation.
