When should rescuers continue CPR until?

Rescuers should continue CPR until help arrives or the person shows signs of life because these criteria indicate that the need for continuous life-saving intervention has changed. If medical professionals arrive, they have the tools and training to take over care effectively. Alternatively, if the person begins to show signs of life—such as coughing, breathing normally, or responding appropriately—it signifies that the heart has resumed function, and CPR is no longer necessary. This approach ensures that life-saving measures are sustained until the situation is safely handed over to qualified personnel or until the individual demonstrates recovery. Continuing CPR in these scenarios maximizes the chances of survival and recovery for the victim.
