Which of the following is an appropriate reason to stop performing CPR?

Stopping CPR is appropriate when emergency professionals arrive on the scene because they are equipped and trained to take over the care of the victim. Once they arrive, they can assess the situation, provide advanced medical care, and determine the next steps for the patient. This transition of care is essential as healthcare professionals have access to additional equipment and medications that are not available to bystanders. The presence of trained emergency responders also alleviates the burden on the bystander who is performing CPR, allowing them to step back without guilt, knowing that the victim is now in capable hands.

While other circumstances may prompt a reconsideration of whether to continue CPR, they do not represent universally appropriate reasons to stop. For instance, an unconscious victim still requires lifesaving measures, and stopping CPR simply because someone else requests it may not be justified, especially if the person's potential as an emergency responder is unknown. Similarly, while it's important to monitor the duration of CPR, there is no strict time limit like 20 minutes that automatically dictates when it should stop; providing continuous CPR until professional help takes over is the best practice.
