How should a rescuer position their hands when performing CPR on a child?

When performing CPR on a child, using one or two hands to compress the chest about 1.5 inches deep is appropriate because it balances the need for effective compressions with the physical size of the child. Compressing to a depth of 1.5 inches is typically sufficient to create necessary blood flow during cardiac arrest, as children have smaller, more flexible bodies than adults.

One hand may be adequate for smaller children, while two hands might be needed for larger children to achieve the necessary depth and force of compressions effectively. This depth is crucial because compressions must be deep enough to pump blood effectively through the heart and circulate oxygen to vital organs. Additionally, maintaining a rate of at least 100 to 120 compressions per minute aligns with recommended guidelines for effective CPR.

In contrast, using one hand compressing to only about 1 inch deep does not provide adequate blood flow, and two hands compressing to 2 inches deep may be excessive, potentially causing injury to the child. Keeping hands off the chest until help arrives is not an option, as immediate action is critical in a cardiac emergency. Therefore, the proper positioning and depth for compressions is essential for a successful resuscitation outcome.
