Give a stream of consciousness and then the final answer. Hospital emergency codes have often varied widely by location, even between hospitals in the same community. Confusion over these codes has led to the proposal for and sometimes adoption of standardized codes. In many American, Canadian, New Zealand and Australian hospitals, for example "code blue" indicates a patient has entered cardiac arrest, while "code red" indicates that a fire has broken out somewhere in the hospital facility.

Based on this passage, what does code red mean in the emergency room?
To answer the question, consider the following: In many American, Canadian, New Zealand and Australian hospitals, for example "code blue" indicates a patient has entered cardiac arrest, while "code red" indicates that a fire has broken out somewhere in the hospital facility.
So, the final answer is a fire has broken out somewhere in the hospital facility.
