Clinicians sometimes gather the evidence of hypovolemic and septic shocks by looking at patient’s central venous oxygen saturation (ScvO2) from blood samples taken from the central internal jugular vein. This procedure is invasive for patients and cumbersome for clinicians. Now researchers at the University of Electronic Science and Technology of China are reporting on a new non-invasive optical probe that can measure continuous tissue blood oxygen saturation (StO2) jst over the jugular vein area.
