What is the compression depth required for effective CPR on a child?

The compression depth required for effective CPR on a child is well established as being about 2 inches or approximately one-third of the child's chest depth. This depth is vital because it allows for adequate blood flow to vital organs during compressions, which is essential for maintaining circulation when the heart has stopped beating effectively.

Compressing to this depth helps ensure that enough pressure is generated to overcome the resistance of the chest wall and create the necessary blood flow to the brain and other critical areas of the body. It's important for first responders to adhere to this guideline to increase the likelihood of survival and recovery.

The alternatives provided do not meet the appropriate depth needed for effective compressions in children. Compressions that are too shallow won't generate enough blood flow, while compressions deeper than the recommended depth may cause injury to the child. Thus, knowing the correct depth and applying it correctly is crucial for effective CPR in pediatric patients.
