What is the term for the return of color to the skin after pressure is applied and released?

The term for the return of color to the skin after pressure is applied and released is known as capillary refill. This phenomenon reflects the time it takes for blood to return to the capillaries after they have been momentarily occluded. When pressure is applied to the skin, blood is temporarily forced out of the small capillaries, leading to a paler appearance. Once the pressure is released, the color returns as blood flow resumes, indicating good circulation and perfusion to the tissues.

This measure is commonly used in clinical settings as part of a physical examination to assess circulation and overall vascular health. The speed of capillary refill can provide valuable information about a patient's cardiovascular status, particularly in emergency situations or when evaluating for shock.
