What is the one-responder CPR cycle for a child?

The one-responder CPR cycle for a child consists of 30 compressions followed by 2 ventilations. This ratio is designed to optimize the potential for successful resuscitation. In the case of pediatric patients, the compressions should be performed at a rate of 100 to 120 per minute, with a depth of about 2 inches (5 cm).

This balance of compressions and ventilations is critical because compressions serve to maintain blood flow and oxygen delivery to the vital organs, while ventilations provide the necessary oxygen to the lungs. While this cycle applies specifically to one-responder scenarios, the ratio might differ when more responders are involved, emphasizing the importance of following the correct protocol for the situation at hand. The other options do not adhere to the established guidelines for pediatric CPR, which emphasizes the 30:2 compression-to-ventilation ratio for single rescuers.
