Abstract
A system and associated method provide tissue perfusion monitoring in a patient. A laser Doppler unit is provided including a coherent laser light source and a photodetector. A processor is configured to receive a signal from the photodetector and determine a tissue perfusion measurement from a Doppler-shifted component of the photodetector signal. A wireless communication circuit transmits the tissue perfusion measurement. A power source provides power to the laser Doppler unit, the processor and the communication circuit. A wireless housing encloses the laser Doppler unit, the processor, the power source and the communication circuit.
