For a child, what is the CPR compression to breath ratio for one rescuer?

For a child, the CPR compression to breath ratio for one rescuer is 30 compressions to 2 breaths. This means that when performing CPR, you would administer 30 chest compressions followed by 2 rescue breaths. This ratio is designed to provide adequate circulation and oxygenation to the child during a cardiac arrest, as the compressions help to pump blood and keep the heart functioning, while breaths deliver oxygen to the lungs.

The ratio is influenced by the recognition that strong, consistent compressions are crucial for maintaining blood flow to vital organs. The emphasis on a higher number of compressions (30) compared to breaths (2) reflects an understanding of the importance of doing compressions effectively and efficiently to sustain circulation until emergency medical services arrive or the child shows signs of life.
