What indicates an abnormal capillary refill time in an infant?

An abnormal capillary refill time in an infant is indicated by a time that is more than 2 seconds. Capillary refill time is a crucial assessment in determining peripheral perfusion and circulatory status, especially in pediatric patients. For infants, a normal capillary refill time typically ranges from 1 to 2 seconds. If the refill time exceeds 2 seconds, it suggests that the infant may be experiencing inadequate blood circulation or potential shock, which warrants further evaluation and possible intervention.

In contrast, a capillary refill time of less than 1 second tends to be considered normal as it reflects good perfusion. A capillary refill time equal to 2 seconds is also within the normal range, as it indicates adequate blood flow to the extremities. Finally, a refill time between 1 to 2 seconds again aligns with standard assessments for normal perfusion. Thus, the threshold for concern specifically lies at more than 2 seconds, marking it as abnormal and potentially indicative of underlying health issues.
