In a team-based resuscitation attempt, especially with the arrival of additional rescuers, the following actions should occur next to ensure efficient and effective resuscitation:

1. Assign Roles:
   • Clearly assign specific roles to each rescuer. For example:
     • Rescuer 1: Continues providing high-quality chest compressions.
     • Rescuer 2: Prepares to deliver ventilations (using a bag-valve mask if available).
     • Rescuer 3: Prepares the AED and manages the defibrillation process.
2. Rotate Compressors:
   • Rotate the person performing chest compressions every 2 minutes to prevent fatigue and maintain high-quality compressions. This should be done quickly to minimize interruptions.
3. Ventilation:
   • Rescuer 2 should provide ventilations at a ratio of 15 compressions to 2 breaths if an advanced airway is not in place (for a child), or provide continuous compressions with 1 breath every 2-3 seconds (20-30 breaths per minute) if an advanced airway is in place.
4. Apply the AED:
   • Rescuer 3 should attach the AED pads to the child’s bare chest and follow the AED prompts.
   • Ensure everyone stands clear of the child while the AED analyzes the heart rhythm and delivers a shock if advised.
5. Continue CPR:
   • Resume CPR immediately after the AED shock or if no shock is advised.
   • Continue cycles of 15:2 compressions to ventilations, rotating roles every 2 minutes to ensure high-quality CPR.
6. Effective Communication:
   • Use clear and effective communication among team members to coordinate actions and ensure everyone knows their role and responsibilities.
7. Monitor and Adjust:
   • Continuously monitor the child’s response and the quality of resuscitation efforts, making adjustments as necessary.
8. Prepare for Advanced Care:
   • If additional medical equipment or personnel (such as paramedics) arrive, provide them with a clear and concise report on the child’s status and the actions taken so far.
