What action should be taken after 2 minutes of CPR if additional help is available during a child or infant's arrest?

In the scenario of a child or infant's cardiac arrest, after 2 minutes of CPR, having additional help available means it's critical to ensure that emergency services are activated promptly. Activating EMS, or Emergency Medical Services, is essential because it brings professional medical assistance to the scene as quickly as possible. This step is vital for the ongoing treatment and management of the child or infant's condition.

While switching CPR roles can be beneficial to prevent fatigue and ensure high-quality chest compressions, it is not the first action to take when another provider is available. The priority should be to ensure that emergency assistance is on the way.

Defibrillation is only indicated for certain arrhythmias such as ventricular fibrillation or ventricular tachycardia, and it is not typically a first-line action in the case of pediatric patients without prior assessment. Securing the airway is also part of advanced care but should follow the activation of EMS as the immediate priority.

Therefore, requesting the help provider to activate EMS ensures that further professional support is being mobilized while CPR continues, leading to better overall outcomes for the child or infant.
