DiCART TM Device for Capillary Refill Time Measurement

To estimate peripheral perfusion in shock state, international guidelines recommend the use of capillary refill time, and practitioners currently evaluates it at bedside. However its measurement is not standardized, what should explain the large observer variability reported in different studies. Hence, a device providing a standardized evaluation seems to be helpful. The aim of the study is to evaluate diagnostic performance of such a device recently developped (DiCART TM), in healthy volunteers experiencing vascular occlusion tests to induce impaired perfusion.
