The document introduces the Pediatric Acute Care Score (PACS), an objective assessment tool used to recognize the early deterioration of pediatric patients. PACS uses a scoring system to evaluate six components: respiratory rate, oxygen saturation, AVPU level, temperature, capillary refill time, and mottling/cyanosis. Lower PACS scores indicate less severe illness, while higher scores suggest greater risk. Three scenarios describe pediatric patients and ask the reader to determine their physiological status and predicted PACS score based on their reported vital signs and symptoms. The goal of PACS is to enable early recognition and response to deterioration, prevent avoidable deaths, and improve communication about patient condition.
