What should you do if you are the only rescuer and an adult is unresponsive?

When an adult is unresponsive, the priority is to ensure that emergency medical services are alerted as soon as possible. In a scenario where you are the only rescuer, the recommended course of action is to quickly activate the emergency response system. By calling for emergency medical services first, you secure help that can provide additional support and resources, making it critical for the patient's chances of survival. This step ensures that even while you are performing CPR, trained professionals are on their way to assist.

Initiating CPR promptly is vital, but if you are alone, calling for help first allows you to focus on the task of resuscitation knowing help is on the way. This approach aligns with the standards of care taught in emergency medical response training protocols, emphasizing the importance of activating emergency medical services early in the resuscitation process.
