Medical examiner: Kids can survive incredible trauma, but when they crump…they crump quick. Detective1: Crump? Detective2: All the vitals go south all at once.
It's a dialogue from TV drama. I found out what 'crump' means in medical situation. It is a slang medical term indicating that a patient's medical condition is rapidly worsening. (I found it on Urban Dictionary)
But I couldn't find what 'vitals go south' means. Maybe it means 'the pulse is dropping'?
Help me please. :(((
