The InSpectra™ Tissue Spectrometer provides a quantified measurement of local tissue oxygen saturation (StO2). The measurement of StO2 is taken with a noninvasive, fiber optic light that illuminates tissues below the skin. The light is absorbed differently based on the amount of oxygen in the tissue. Research has shown that the thenar eminence muscle is an easily accessible and robust site for StO2 monitoring.

StO2, as measured by Hutchinson Technology’s Tissue Spectrometer, is being clinically studied as a potential measure of hemorrhagic and septic shock status.
