Abstract :
Near-infrared spectroscopy (NIRS) provides a new technology to continuously and noninvasively monitor tissue oxygenation. Using a NIRS system of our design, we monitored relative cerebral oxygenation changes of patients undergoing cardiopulmonary bypass. The results of our study show that our NIRS system is a promising monitor for this and other applications
