Which symptom indicates poor perfusion in a pediatric patient?

Cold extremities in a pediatric patient are a key indicator of poor perfusion. When the body experiences inadequate blood flow, often due to shock or other medical conditions, the extremities may become cold to the touch as blood is shunted away from peripheral areas to maintain circulation to vital organs. This is a physiological response aimed at preserving core body function, which is critical in emergencies.

In contrast, a decreased respiratory rate can indicate various issues, but it is not a direct sign of poor perfusion. High blood pressure may sometimes suggest adequate circulating volume or stress responses, and warm skin typically indicates effective perfusion, as warmth usually correlates with sufficient blood flow to the skin and extremities. By recognizing cold extremities as a sign of poor perfusion, health providers can prioritize interventions for the management of shock in pediatric patients.
