What is the immediate response required for a Code Green situation?

In a Code Green situation, the immediate response required is to respond to an active shooter. This code indicates a high-priority emergency that involves an imminent threat to the safety of individuals within the hospital. The primary focus in such a situation is to ensure the safety of patients, visitors, and staff by implementing lockdown procedures, facilitating evacuation if safe to do so, and engaging law enforcement as necessary.

Understanding the context of a Code Green emphasizes the urgency of protecting lives in a hostile scenario rather than addressing other potential emergencies. Each response is geared toward specific threats; for instance, while evacuation is a critical response in fire situations or other evacuations, it may not be the most immediate step in the face of an active shooter where situational awareness and securing safety are top priorities. Similarly, preparing for an internal disaster or attending to medical emergencies such as a stroke would be inappropriate responses in the context of an immediate threat from an active shooter.
