How do you perform CPR on a child?

When performing CPR on a child, using one hand for compressions at a depth of about 2 inches is the appropriate technique. This method takes into account the smaller size and more delicate anatomy of a child's body compared to an adult. The recommended depth of compressions is about 2 inches to ensure adequate blood flow to vital organs while minimizing the risk of injury.

Using one hand allows the rescuer to have better control and precision, which is important for effective compressions. The emphasis on compressing to the appropriate depth ensures that there is sufficient pressure to circulate blood, especially in the critical situation where a child's life is at stake. It's essential to also allow for full chest recoil to enhance blood flow back to the heart between compressions.

This approach is different from the other methods, such as using two hands or compressing to different depths, which do not align with the guidelines for pediatric CPR. Keeping the compressions focused and effective is vital for maximizing the chances of survival until advanced medical help arrives.
