During the capillary refill test, what indicates proper circulation?

The correct indication of proper circulation during the capillary refill test is when the nail turns white and then returns to its normal color (red) within 2 seconds. This response demonstrates that the blood is flowing adequately back to the extremities after a temporary restriction of blood flow, which is indicated by the nail turning white.

Capillary refill time is a quick test used to assess the circulatory status of a patient. A return to a healthy color (red) within the normal timeframe of 2 seconds suggests that the capillaries are functioning properly and that there is adequate blood flow to the tissue. This is particularly important in emergency situations where quick assessment of circulation is critical.

In contrast, other outcomes such as the skin remaining white for 2 seconds or the nail turning yellow, indicate either delayed circulation or other underlying issues. A nail that remains pink throughout the test suggests normal circulation but does not provide the specific evidence of circulation returning after a brief occlusion, which is the primary objective of the capillary refill assessment.
