What does a decrease in capillary refill time indicate?

• A. Improved circulation
• B. Potential heart failure
• C. Increased blood pressure
• D. Higher risk of dehydration

Answer: (A)

Decreased capillary refill time is an important clinical indicator of peripheral circulation. When capillary refill time is reduced, it generally signifies that blood is returning to the capillaries more quickly, reflecting improved circulation. In a healthy individual, when pressure is applied to a nail bed or skin, the blood temporarily leaves those capillaries. Upon release, the capillary refill time should be prompt, typically less than two seconds. A quicker refill indicates that blood flow is adequate and the circulatory system is functioning effectively to deliver oxygen and nutrients to tissues. In contrast, an increase in capillary refill time might suggest issues such as poor circulation, dehydration, or shock, highlighting problems with blood flow or hemoglobin levels. Therefore, recognizing a decrease in capillary refill time can provide reassurance regarding a patient’s circulatory status.
