What does Code 1000 mean?

• A. Welfare check
• B. Emergency
• C. Alert
• D. Medical emergency

Answer: (D)

Code signals are designed to tell responders exactly what kind of incident is happening and how urgently to respond. In this system, Code 1000 is reserved for a medical emergency, meaning a medical crisis requiring immediate EMS intervention. This prompts paramedics or emergency medical responders to respond with priority and brings any necessary medical equipment to the scene, often with pre-arrival guidance to the caller.

This differs from a welfare check, which is about confirming someone's safety and may not involve a medical crisis. It also differs from a general emergency, which could cover non-medical incidents like fires or violent events, and from an alert, which is too broad and not specific to a medical situation. Keep in mind that code meanings can vary by agency, but within this material, Code 1000 indicates a medical emergency.
