What should be done if a child's pulse becomes absent after checking?

When a child's pulse is absent, the most critical step is to start CPR immediately. This is essential because the absence of a pulse indicates that the heart is not effectively pumping blood, which can lead to organ failure and death within minutes. CPR helps maintain circulation and oxygenation of vital organs until advanced medical help arrives.

Starting CPR immediately allows for chest compressions, which can help to artificially circulate blood and provide some level of oxygenation to the brain and other organs. This is crucial in increasing the chances of a positive outcome, especially in a child where every moment counts.

While rescue breathing alone can be necessary in some situations (for example, in cases of drowning), the absence of a pulse indicates a critical and life-threatening scenario requiring immediate chest compressions alongside rescue breaths. Checking for signs of life again is not advisable after confirming an absent pulse; it takes valuable time away from potentially life-saving actions. Notifying emergency services is important, but it should be done concurrently with starting CPR if you are alone or prioritized if you have someone else to assist you.

Overall, the immediate initiation of CPR is the best course of action for a child without a detectable pulse, as it can significantly improve survival chances.
