What is the CPR compression ratio for children when there is one rescuer?

The correct answer is based on the guidelines for performing CPR on children when there is one rescuer involved. The recommended compression ratio for performing CPR on children is 30 compressions to 2 breaths. This ratio is designed to maximize the effectiveness of chest compressions while ensuring that breaths are still delivered to provide adequate oxygenation.

In terms of the depth of compressions, the guidelines recommend compressing the chest to approximately one-third the depth of the chest. This typically translates to around 2 inches for a child, ensuring that the compressions are effective in promoting blood circulation during cardiac emergencies.

Choosing the right compressions and breaths ratio, as well as the correct depth, is crucial for ensuring the best possible outcome for a child in need of resuscitation. This approach aligns with the practices that prioritize high-quality chest compressions over other factors.
