Approximately 1 million patients present to emergency departments in the United States with sepsis annually and each hour delay in recognition results in an 8% increase in mortality. Unfortunately, sepsis is a challenging diagnosis to make early in its disease course due to reliance on subjective measures and laboratory studies. Capillary refill time (CRT) has been shown to be effective at both early recognition and monitoring of sepsis. Yet, CRT remains a subjective measure due to lack of instrumentation.
