OxiplexTS200 is a noninvasive tissue oximeter for the measurement of the absolute concentrations of oxy- and deoxy-hemoglobin in tissues (muscle and brain); from these parameters, the instrument determines the total hemoglobin content and the oxygen saturation of the tissue. The determination of the hemodynamic parameters is based on real-time measurement of the optical properties of the tissue. Unlike other commercial devices that make longitudinal assumptions on the optical properties of the tissues, OxiplexTS200 measures the actual parameters in each subject, and therefore provides a measurement specific to the subject. The underlying algorithm used by the instrument (frequency-domain multi-distance) has been developed by researchers at the University of Illinois and is covered by intellectual property agreements. Applications include ones related to peripheral vascular disease, sleep apnea, brain oxygenation monitoring, and sports medicine.
