After delivering a shock, who should start CPR immediately, beginning with compressions?

The person who should start CPR immediately after delivering a shock is the trained responder who administered the shock. This responder is typically the one who is most familiar with the proper techniques and the rationale behind starting CPR. They have been trained to act quickly and effectively in this type of emergency, ensuring that compressions begin promptly, which is critical for maintaining blood flow to the brain and other vital organs.

Starting CPR immediately after delivering a shock is essential because even though the shock may restore a normal heart rhythm, the individual may still be unresponsive and not breathing normally. The trained responder is also more likely to recognize the signs of continued cardiac arrest and follow established protocols effectively.

While other team members may indeed be helpful, the individual who administered the shock is usually in the best position to continue with the life-saving steps of CPR without hesitation or confusion. The urgency of the situation necessitates rapid and proficient action, making the trained individual the optimal choice to take the lead in providing CPR.
