What is the correct ratio of compressions to ventilations during two-rescuer child CPR?

1. 15:2

2. 30:2

3. 5:1

4. 10:2

The correct answer is: 15:2

In two-rescuer CPR for a child, the correct ratio of compressions to ventilations is 15:2. This particular ratio is important because it balances the need for effective chest compressions, which are crucial for maintaining circulation and oxygenation, with the need for ventilations to ensure that the child is receiving adequate oxygen. In this setting, one rescuer performs chest compressions while the other provides ventilations. The 15:2 ratio indicates that for every 15 compressions delivered, 2 breaths should be given. This is based on guidelines that emphasize the importance of maintaining blood flow while still addressing the need for oxygen delivery, especially in pediatric patients who may have different respiratory and cardiac needs compared to adults. It's significant to note that in adult CPR and in many other situations, the compression to ventilation ratio is often 30:2, which emphasizes more compressions due to larger body size and the typically higher risk of cardiac-related events. In contrast, children are often more likely to experience respiratory issues, so the increased frequency of ventilations in the 15:2 ratio is warranted. This understanding highlights the importance of adapting CPR techniques based on the age and physiological needs of a patient, ensuring the best chance of survival
