Is there an origin story behind IV gauge color codes — who decided 18g is green, 20g pink, 22g blue? Was that an actual standard or just vendors converging over time? I sharpie a tiny cheat on the IV tray to save a few seconds, but I’m hunting for a faster cross-brand mnemonic when the cart’s a mix.
There’s an ISO standard behind it now (ISO 10555-5/6009), so most brands stick to 18=green, 20=pink, 22=blue; quick chart here: https://www.bbraun.com/en/products/b0/vasofix-safety.html. I use the traffic-light mnemonic — green = go fast, pink = routine, blue = be gentle — and slap a tiny label. Small caveat: a few peds/specialty lines still break the palette; do you see any outliers in your mix?
