A capillary refill time of greater than 3 seconds in an infant indicates what?

A capillary refill time of greater than 3 seconds in an infant is indicative of decreased cardiac output. In infants, capillary refill time is an important assessment tool used to evaluate perfusion and overall circulatory status. A normal capillary refill time is typically less than 2 seconds. When refill time exceeds 3 seconds, it suggests that the body is not effectively circulating blood, which can be a sign of inadequate cardiac output.

Decreased cardiac output can be caused by various factors, including heart failure, shock, dehydration, or other conditions affecting the heart's ability to pump blood efficiently. In infants, rapid assessment and recognition of changes in capillary refill time is critical since they can deteriorate quickly. A prolonged capillary refill time should prompt further assessment and potential intervention to address the underlying causes affecting circulation.
