What is the first step to take when treating a pediatric patient in full cardio-pulmonary arrest?

The first step to take when treating a pediatric patient in full cardio-pulmonary arrest is to perform cardiopulmonary resuscitation (CPR). This action is critical because CPR is designed to maintain circulation and oxygenation to vital organs until advanced life support can be provided. When a child experiences cardiac arrest, immediate CPR can significantly improve their chances of survival by promoting blood flow to the heart and brain.

Obtaining IV access, administering medications like epinephrine, or calling for additional help are important components of the overall management of a pediatric patient in arrest, but they should not take precedence over initiating CPR. Performing CPR right away ensures that the patient receives the necessary support while additional resources are mobilized.
