If you discover a child in cardiac arrest and are alone, what should you do first?

Starting CPR immediately is crucial in a situation where a child is in cardiac arrest. This decision is rooted in the urgency of restoring circulation and oxygenation to the brain and other vital organs, as the likelihood of survival depends on prompt intervention. Performing about 2 minutes of CPR, beginning with chest compressions, helps to generate blood flow and can preserve brain function until advanced help arrives.

In the absence of immediate assistance, you must take action to maintain blood circulation. Chest compressions provide critical blood flow to the heart and brain, which can make a significant difference in the outcome.

Other options may not prioritize the child’s immediate needs effectively. For example, delivering two initial ventilations or placing the child in a recovery position do not address the immediate lack of circulation and could result in a delay that jeopardizes the child's chance of survival. Similarly, carrying the child to find help fails to provide essential life-saving measures on the spot, which are necessary while waiting for emergency assistance.
