Children's Hospital Early Warning Scoring (CHEWS) System
This video will discuss risk factors for pediatric cardiopulmonary arrest and an early warning-scoring tool and algorithm for arrest prevention.

Learning Objectives
Describe the purpose of pediatric early warning scoring systems and explain their role in the early recognition of clinical deterioration and prevention of cardiopulmonary arrest.
Identify risk factors, warning signs, and physiologic indicators associated with impending pediatric cardiovascular or respiratory compromise, including abnormalities in behavioral, cardiovascular, respiratory, and oxygenation status.
Apply a pediatric early warning scoring tool to assess patient condition by assigning appropriate scores across clinical domains and calculating an overall risk score.
Analyze pediatric patient scenarios using early warning score findings and clinical assessment data to determine the level of deterioration and the need for escalation of care.
Evaluate appropriate interventions and escalation pathways based on early warning scores and changing patient status to support timely treatment and prevent progression to critical events.
