I read in the WP today the word "coded".
A physician in Kentucky, used it in this way:
I had never heard the word "coded" before used in a medical situation.
At first, in my ignorance, I thought it meant "to die of covid", but of course it only means that there was an alert.
Coding means when a person is in need of immediate aid of some sort. And in this situation, refers to a person needing resuscitation.
Language is truly a living social construct. Constantly emerging and morphing.
