BabyLux – An Optical Neuro-Monitor of Cerebral Oxygen Metabolism and Blood Flow for Neonatology – is a project that aims to provide an innovative and reliable tool to monitor and assess brain blood flow and oxygenation in extremely preterm neonates. The device can be brought to the bedside, measurements can be done in a few minutes and repeatedly, if the condition is critical. The project takes up complete R&D works and extends already tested prototypes to the level of demonstrator.
