🎯 FAIR: Cold vs Warm Shock in Children

F — Fatal: Wrong vasopressor match worsens outcomes; up to 30% of children convert phenotypes mid-resuscitation
A — Assess: 4-point check in <60s — cap refill at sternum, pulse quality, extremity temp gradient, pulse pressure
I — Intervene: Cold shock → epinephrine; Warm shock → norepinephrine; When unsure → epinephrine first
R — Repeat: Reassess every 5-15 min; track extremity demarcation line for phenotype conversion
