When should you start CPR on a child?

Starting CPR on a child is indicated primarily when there is an absence of a pulse. This is a critical criterion because the absence of a pulse signifies that the heart is not effectively pumping blood to the body, resulting in a lack of oxygen to vital organs. Without timely intervention through CPR, the risk of irreversible damage increases significantly.

In scenarios where breathing is erratic or signs of life are present, CPR may not be necessary. The presence of a pulse or any signs of life suggests that the cardiovascular system is somewhat functional, and immediate CPR may not be warranted. Monitoring the heart rate is also important, but a heart rate above 60 beats per minute usually indicates some level of circulation and does not require CPR in a child. Thus, beginning CPR in the event of an absent pulse is a critical lifesaving measure.
