So we used a color system that's mostly standardized. Code blue is respiratory or cardiac arrest, code red is fire, code gray is security, etc. we're changing to plain language as that's been shown to be best practice. Everything is still a code though. We've had code trauma, code stemi, code stroke. We also have rapid response for anything that doesn't meet a code criteria but still needs assistance. My favorite was code brown for severe weather alert as that was our slang for cleaning a patient.
