What is the normal capillary refill time?

• A. < 2 seconds
• B. > 5 seconds
• C. 2-4 seconds
• D. 4-6 seconds

Answer: (A)

Capillary refill time is a quick check of peripheral perfusion. By pressing the nail bed until it blanches, you assess how fast blood returns to the area once pressure is released. In healthy individuals, color returns promptly, typically within two seconds. This quick return indicates adequate blood flow and circulating volume. If the return is delayed beyond about two seconds, it can signal reduced peripheral perfusion from dehydration, shock, or other circulatory problems, requiring urgent attention. So the normal capillary refill time is under two seconds. Times longer than two seconds aren’t normal and suggest possible perfusion issues, though factors like temperature and finger conditions can influence the measurement, so interpret it within the overall clinical picture.
