When performing single-provider CPR on a child, what is the compression-to-ventilation ratio?

In single-provider CPR for a child, the correct compression-to-ventilation ratio is 30:2. This ratio refers to the number of chest compressions to rescue breaths given during each cycle of CPR.

When performing CPR, the primary objective is to maintain blood flow to vital organs. Chest compressions are critical in this process, as they help circulate oxygenated blood. After every 30 compressions, two rescue breaths are provided to supply oxygen directly to the lungs. This approach aligns with guidelines that aim to optimize the efficacy of CPR in pediatric patients, balancing the need for compressions and ventilations.

Using this specific ratio ensures that the rescuer delivers adequate compressions while also providing the necessary breaths to support the child's breathing, thus increasing the chances of restoring heart function and overall survival.
