Non-invasive Device for Continuous Measurement of Brain Oxygen Supply Demand Using Near-Infrared Spectroscopy

Monitoring brain oxygen supply and demand is crucial for assessing cerebral perfusion and oxygenation in various medical conditions. This study presents a non-invasive device for continuous measurement of brain oxygen supply demand using near-infrared spectroscopy (NIRS). The device incorporates NIRS sensors placed on the neck side to measure Jugular venous oxygen saturation (SJVO₂) and Carotid saturation (SaO₂) calculates key parameters related to brain oxygen supply and demand. By providing real-time and continuous monitoring, this device offers valuable information for clinical decision-making and intervention strategies. The feasibility and performance of the device were evaluated through validation studies, demonstrating its potential as a valuable tool for non-invasive monitoring of brain oxygen supply demand in critical care, surgical procedures, and other medical settings. The device represents a significant advancement in the field of cerebral oxygenation monitoring, offering a non-invasive alternative to invasive procedures and facilitating timely interventions to optimize patient outcomes.
