Which of the following indicates that CPR should be stopped?

The correct choice indicates that CPR should be stopped when either the victim starts breathing normally or when emergency personnel arrive.

When the victim begins to breathe normally, it signifies that their heart is functioning adequately, and they no longer require the artificial support of CPR. Restoring spontaneous respiration is a primary goal during resuscitation efforts, as it indicates improvement in the victim's condition.

Similarly, the arrival of emergency personnel means that trained responders are now capable of taking over the care of the victim. This is crucial because these professionals have advanced training and equipment to provide further medical assistance.

Stopping CPR in these two scenarios allows for a smooth transition to further medical assessment and treatment, ensuring that the victim receives the best possible outcome in a timely manner.
