What is the pediatric triangle of assessment (PAT)?

The pediatric assessment triangle is a tool that can be used to rapidly assess the respiratory status of a pediatric client, particularly to identify critically ill or injured children. 

In emergency situations, the rapid assessment can help prioritize patients by identifying children at risk of decompensation. It is applicable across all pediatric age groups. 

Components of the pediatric assessment triangle

The assessment triangle is based on 3 key observations: appearance, work of breathing, and circulation.
