  • SYSTEMS, DEVICES AND METHODS FOR MONITORING HEMODYNAMICS
    Publication number: 20140323879
    Abstract: Systems, devices and methods for monitoring hemodynamics are described. The systems and methods generally involve directing light toward an area of the body and detecting the resulting scattered light. The scattered light is detected and an electrical signal representative of the scattered light intensity is generated from the detected light. The electrical signal is analyzed by measuring temporal fluctuations of such signals to monitor pathological states over time including hemorrhagic shock, hypoxia, and tissue graft vascularization. Such monitoring can have significant benefits to patients.
