When performing CPR on a child with a heart rate less than 60 and signs of poor perfusion, what is the appropriate compression to ventilation ratio for two rescuers?

In the context of performing CPR on a child, especially when the child presents with a heart rate of less than 60 and signs of poor perfusion, it is crucial to ensure high-quality chest compressions and appropriate ventilation. The recommended compression-to-ventilation ratio for two rescuers in pediatric CPR is 15 compressions followed by 2 breaths. This approach not only provides sufficient blood circulation to vital organs but also ensures that the child receives enough oxygen through positive pressure ventilation.

Using this ratio takes into account the physiological differences between adults and children. Children have a higher metabolic demand and therefore require more frequent breaths relative to compressions. The 15:2 ratio ensures that the child receives adequate ventilation without compromising the effectiveness of chest compressions. This is particularly important as poor perfusion indicates inadequate blood flow, and maintaining effective compressions while providing timely ventilations can significantly improve the child's chances of recovery.

The other ratios provided are inappropriate for this scenario: a 30:2 ratio is used in adult CPR and not suitable for children's needs, while a 2:15 ratio would not provide enough compressions, and a 5:1 ratio is not a recognized standard in CPR practice. By following the 15:2 ratio, rescu
