When two rescuers are performing CPR on an infant or child, what compression ratio should they use?

When two rescuers are performing CPR on an infant or child, the recommended compression-to-ventilation ratio is 15 compressions to 2 breaths. This ratio is designed to provide an effective balance between maintaining blood circulation and ensuring adequate oxygenation.

In the context of pediatric patients, using a 15:2 ratio allows for a higher frequency of compressions relative to breaths, which is vital because infants and children have different physiological needs compared to adults. This approach focuses on the importance of oxygen delivery while still maintaining sufficient circulation through compression.

Other ratios such as 30:2, 20:2, or 25:2 are not aligned with current guidelines for pediatric CPR in situations with two rescuers, as they may not provide optimal chest compression rates and could potentially lead to inadequate oxygenation for the patient. Therefore, the 15:2 ratio serves as the standard during two-rescuer pediatric CPR, ensuring effective life-saving measures are taken.
