What is the first action to take in a medical emergency?

In a medical emergency, the first action should be to call 911 and follow instructions. This step is crucial because it ensures that professional medical help is on the way as soon as possible. The dispatcher can provide vital instructions that may be necessary while waiting for emergency responders to arrive, including guidance on how to assist the victim until help arrives.

Alerting emergency services via radio or performing CPR may come later, depending on the situation and the instructions received from the operator. Evacuating the building is typically only necessary in specific scenarios, such as when there is a danger to individuals inside the building, and may not be the first action to take in a straightforward medical emergency. Therefore, prioritizing the call for help and obtaining guidance is the most effective way to start addressing a medical crisis.
