In pediatric patients, the recommended compression-to-ventilation ratio for CPR is 15:2. This ratio applies specifically when two rescuers are present, ensuring that adequate chest compressions are delivered alongside effective ventilations. The rationale behind this specific ratio is rooted in the developmental physiology of children. Children have a higher respiratory rate and a higher demand for oxygen than adults, which makes effective ventilation critical during resuscitation efforts.

Using a 15:2 ratio allows for more frequent ventilations compared to adults, where a ratio of 30:2 is standard. This emphasis on providing more breaths is particularly important for pediatric patients, who are more prone to respiratory issues that can lead to cardiac arrest. The focus on a higher number of compressions in this configuration also helps maintain adequate blood circulation while oxygenation is prioritized.

In a practical scenario, having two rescuers allows for one to focus on delivering efficient chest compressions, while the second can ensure that ventilations are provided without prolonged interruptions. This structured approach increases the chances of successful resuscitation in pediatric emergencies.
