Which of the following describes a sign of decreased perfusion?

Decreased capillary refill is a significant indicator of reduced perfusion, especially in children and infants. Capillary refill time measures how quickly blood returns to the capillaries after they have been compressed, typically assessed by pressing on a nail bed or the skin. A normal capillary refill time is generally less than 2 seconds. When capillary refill time increases (taking longer than normal), it suggests that the blood is not circulating effectively, which can signal inadequate blood flow or perfusion to tissues, often due to conditions such as shock or cardiovascular issues.

Understanding signs of decreased perfusion is crucial for effective assessment and response during emergencies. While other signs of good perfusion include a warm and well-perfused skin color, quick capillary refill, and normal skin temperature, an increased capillary refill time indicates that the body is struggling to deliver blood and oxygen to vital organs, highlighting the potential severity of the situation.
