Who should activate a code blue?

A code blue should be activated by any healthcare professional who identifies a patient in need of immediate resuscitation due to cardiac arrest or respiratory failure. This typically includes nurses, doctors, or other trained staff who are present and able to assess the situation. Prompt activation is crucial, and staff are encouraged to do so without hesitation if they perceive a life-threatening emergency. In many institutions, there are specific protocols in place to guide staff on when and how to activate a code blue.
