What should you do if you encounter a medical emergency while alone?

In a medical emergency, it is critical to ensure that emergency medical services (EMS) are notified as quickly as possible so they can respond to the situation. This prioritizes reaching out for help, as timely intervention from trained professionals can significantly impact the patient's outcome.

When you call 911 first, you initiate the process to get help on the way while allowing you to focus on what needs to happen next. After the call is made, you can then assess the patient, check their responsiveness, conduct a quick evaluation for immediate life-threatening issues, and begin any necessary first aid or CPR if required. This approach ensures that help is on the way while also addressing the patient's immediate needs without delay.

The other options lack the urgency and efficiency required in such situations. Not calling for help first could delay critical care that the patient might need.
