Early identification of sepsis is a crucial responsibility for many clinicians. The capillary refill test is one strategy used; see how well you know this technique.

Capillary refill is the time it takes for blood flow to return to skin capillaries after pressure is applied that drives blood out of the capillaries. Using this technique can indicate symptoms often related to sepsis, and therefore can aid in identifying sepsis or septic shock.
