Tissue saturation oximeter

A tissue saturation oximeter is a non-invasive device that measures the oxygen saturation (StO₂) in tissue, particularly skeletal muscle, to evaluate blood flow and oxygen delivery. Clinically, it helps assess perfusion issues, monitor circulatory function, or detect compromised circulation in conditions like vascular disease or post-surgical recovery.

These devices are typically regulated as medical instruments, often requiring compliance with safety and performance standards depending on the jurisdiction. They are usually supplied as standalone systems, including sensors, cables, and display monitors, and may be classified based on their intended use and risk level.
