The device has four channels where the light sensors will retrieve the lectures from the splanchnic (left flank), mesenteric (infra-umbilical), muscular (either right or left thigh) and cerebral (forehead) areas. The NIRS sensors Cerebral (IS-C) and Somatic (IS-S) Infant/Neonatal Somatic OxyAlert® will be attached directly to the infant skin in order to obtain the area lecture.
