What is the normal capillary refill time for a healthy adult?

The normal capillary refill time for a healthy adult is generally considered to be less than 2 seconds. This measurement is typically assessed by pressing on a nail bed or the skin to temporarily blanch (whiten) the area and then observing how quickly color returns upon release. In healthy individuals, blood flow should resume quickly, reflecting adequate peripheral circulation and cardiovascular status. A refill time of less than 2 seconds indicates good circulation, while longer times may suggest potential issues such as shock or other circulatory problems. Therefore, the 2-second marker is often used as a benchmark for healthy adults in clinical assessments.
