The most appropriate moment to stop CPR is when emergency medical services arrive, when the victim shows signs of breathing, or when the rescuer is unable to continue due to exhaustion. Each of these situations indicates that it is no longer necessary to continue the resuscitation efforts.
When emergency medical services arrive, they are trained to take over care and will have the necessary equipment and resources to continue treatment. Similarly, if the victim begins to show signs of breathing, this indicates that the heart may have resumed its function, which is a crucial sign that CPR is no longer required. If the rescuer becomes too fatigued and is unable to effectively perform CPR, it is important to stop to ensure that any ongoing attempts are performed effectively by someone who is able.
All these scenarios highlight critical moments in the resuscitation process when it is safe and appropriate to cease CPR, ensuring that the victim receives the best possible care at all times.
